How does your restricted 33bhp pointy SV650 feel?

[Catflavor]

I'd appreciate it if people who have regularly ridden a restricted pointy could let me know if they've had the same experience as me.

My girlfriend just bought a 2003 pointy 650 and had it restricted by the bike shop (who ****ed it up the first time around - I rode it away and the fuel injection warning appeared within a mile). She can't ride it for a few weeks as she's recovering from a shoulder op, so I rode it home for her ...and then rode it around a bit since it reminded me of my old curvy (I'm on a zx6r at the moment, but pining for a twin again).

Anyway. The bike seems generally smooth, but occasionally seems to stutter or bog at mid-high revs (about 7k-ish perhaps) and then recovers after a second of hesitation. It doesn't seem to do it every time, but I wondered if people could tell me what their thoughts are. Do other restriction versions sometimes hesitate? The bike is unused at the mo (SORN), so if there is a problem it might not get seen immediately and we'd want to get it back to the shop ASAP.

Also, once she's allowed to ride full power, is de-restricting simply a case of removing parts which were added? Or will she need to replace the parts used in the restriction process with stock parts? If the bike shop has removed bits which she needs to put back on the bike, I'd want to keep them - so we don't have to buy them all over again.

Thanks for any feedback!

PS It was interesting riding the bike post restriction. At 33bhp its still torquey, but it's so much more sedate and civilised...more gentle. If you're riding a 33bhp and waiting to get it de-restricted, boy have you got a treat in store! You can still overtake and get away quick on 33bhp, I did. You just need to shift gears sooner to keep the speed climbing with revs

where do you live?
coz the bike shops near me?

Not ridden a restricted pointy, but I'd have hoped the fueling would still be good and smooth. The ECU is replaced for a restricted one, make sure the garrage give you the full power one back and then it's just "plug & play" to move the 2 units over and go back to full power.

Some garrages *ahem* forget to give you back this £200 box.....

[Catflavor]

Erm, generic "the bike shop", hehe ;)

It was a bike shop in Redhill, Surrey which did it. I'm in Crawley, Sussex.

[monkey]

I thought all they did was plonk a sealed chip between the main loom and the ECU? Is that what they did?

I'm fairly certain it's an entire replacement ECU

[Catflavor]

I just rang the bike shop and they said there's no change to anything electronic, nothing taken out, only parts added.

Apparently its two items: A stop inserted in the throttle (which is obvious, as it only opens about halfway) and some washers in the fuel inlets which restrict the fuelling. I checked if that's only for the curvy version, and he said that's restricted at the fuel inlet to the carbs.

I did resent the guy saying "Yeah right" when I denied I was derestricting it myself. Don't much like being called a liar :|

[jambo]

Well that'll work too I guess:rolleyes:
<derail>Oi, you've stolen a clean version of my bike! </derail>

Erm, I may be the proverbial mechanical numpty, but I could swear the pointy's restriction would be made exclusively by replacing the ECU :shock: I've never heard of that way of doing it! :shock:

[monkey]

I'd get a proper second opinion from another dealer to be honest. They sound like a***s. It's all electronically controlled so there would be no point in adding parts to restrict the fuel when an ECU would do.
:)

Let's know what happens.

[Catflavor]

But if restricting needed a replacement ECU, surely the process would cost more. Since ppl here say that an ECU costs between £200 and £400 (depending on the threads you read).

If you can do it without changing major components, surely that's better and cheaper...

Since the restriction modification (parts and labour and certificated) was less than £150, that suggests it wasn't a whole new ECU.

Does anyone know for certain? "I reckon", or "I imagine"... not so handy ;) Someone here must have installed/removed the kit themselves...?

[amuli]

I had my K6 restricted to 33hp, It is done by replacing the ECU. I put the full power one back in and it is a dream. Once you ride it on full power you wudnt want to go back to the 33hp. Sounds that the garage did a botch job. Mine was done at the main dealer when I bought it new. I would get a second opinion...

[The Basket]

The ristriction is purely electronic and no washers and such.

The bike is as smooth as ever but it does lack power...as I revved it towards the red line. it did not do much and lost power kinda...although it could be simply the rev to horsepower graph...it may be giving its power at lower revs and so no point revving it at the red line.

[amuli]

The restricted ECU costs about 100 quid from a main dealer, if I remember correctly..

[amuli]

I removed the kit myself, its a plug in ECU, took about 15 mins in total

[Catflavor]

Got her to find the paperwork and certificate. It says the items installed are an "inlet blade" and a "throttle stop". Definitely no ECU gubbins...

The bit I am really interested in is the bike performance. It seems fine 95% of the time, with the odd hiccup. Thanks for the feedback folks.

Be interesting to hear from anyone else who has their pointy restricted the mechanical way.

[Kate]

I had a SV650S K3 that was originally restricted by having a restricted ECU box that was then swopped with the normal ecu when de-restriction came about. imo it is far more normal to do it this way (for pointies) than to do it the way you are describing.

As far as how the bike felt, it was fine, the only real difference was that you couldn't really accelerate past 100.

[Catflavor]

Using info from the certificate I've found the supplier of the restrictor:

http://www.fiinternational.com/Restrictors.asp

Its the 04-WVBY-K25

Unfortunately there's no extra info on their pages at all. Still, confirms what the shop said.

[Flamin_Squirrel]

Yes, normally pointy SV's are restricted via a replacement ECU. However, I can't see why a mechanical restriction wouldn't work too, or why it might cause a problem.

I've got a restricted ECU kicking about if you want to try using that instead.

[Catflavor]

Thanks for the speedy responses, people :) It sounds like its worth me checking the performance more closely and figure out whether I was just trying to make 33hp behave like my usual 100+

I don't want to kick up a fuss over nothing. Nothing worse than being told "Nah mate, they're all like that" and having no idea whether you're being spun a yarn.

Cheers!

PS. Flamin Squirrel - We might take you up on your offer if the bike is behaving weirdly. Thanks for the reply!

[jambo]

you may find that the fueling on the standard ECU is having a little trouble with the restriction washers, somewhere with a yoshi box or similar should be able to re-map the stock ECU if this is the case.

You know what, I've noticed that sometimes on a whiff of throttle my restricted curvy has a little hesitation, then carries on fine. I dont worry about it though, I think its just gasping for air.

[dmracing]

I had my bike restricted from new. Its off now though so here is what I know.
A restricted pointy shouldnt feel "unsmooth". The only problem is that from about 7,000rpm onwards there is no grunt. I think full injection warning is coming up due to them messing about with the fuel inlets.

As for the throttle stop and washers, that sounds a bit weird!
Ive got the 33bhp ECU sitting at home. Its a plug and play jobbie and should take 5 minutes to derestrict the bike. I hope you didnt pay anymore than £70 to restrict the bike, if you did, they have ripped you off!

[jamesobrady]

However, I can't see why a mechanical restriction wouldn't work too, or why it might cause a problem.

I've got a restricted ECU kicking about if you want to try using that instead.

FS if you can sell him your ecu that'd be the best idea....
The reason inlet washers work on carbed bikes is, they restrict airflow..which restricts the amount your slider lifts...which restricts the amount of fuel vapour drawn out of the bowl. A hole drilled in the slider as per factory restricted bandits etc does a similar thing.

On the FI sv, you have a double butterfly valve arrangement...the first set is controlled by the throttle.
The fuel and secondary butterflys are controlled by the (restricted) ecu, limiting fuel and air intake.

On a full power ecu with inlet washers all your doing is restricting airflow...afaik the sv doesnt have a MAP/MAF(manifold air pressure/flow) sensor so the ecu cant adjust that much for fuelling.

Maybe the throttle stop helps here......maybe not.
The only thing the FIM route does is it gives you a recognised certificate of restriction.
However if you were to get a restricted ecu(part no: mgt 061 for 33bhp/mgt 060 for full power)
I would wager any suzuki dealership would give you a cert saying its restricted.

It might be an idea to bang the bike on a dyno and it'll tell you exactly what its doing.... f/a mix and hp. If everything is fine then good...you have a cert, a restricted bike, and a full power ecu for later. If not you can then go back to the shop with your dyno printout and say...its crap, take it off...I want an ecu.
Whats a quick dyno run cost with no extra tuning..20/30 bob?
That'd be my first move.......

[Rich]

I don't see how a dealer would go to the trouble of adding parts when all you need is to plug in the ECU. :-s

Take the ECU out from under the seat and check those numbers that jamesobrady gave you, they're on the side of the ECU. If its the full power one then you know its restricted in some other way!

mgt 061 for 33bhp

mgt 060 for full power

[SVeeedy Gonzales]

My restricted K4 didn't feel any different to the unrestricted one. Only whenm you get to about 7000rpm and higher speeds does it get noticeable. The restricted bike wasn't noticeably slower to accelerate up to legal speeds, but struggles to get past an indicated 100, which an unrestricted bike will easily shoot past that.

[jamesobrady]

I don't see how a dealer would go to the trouble of adding parts when all you need is to plug in the ECU. :-s



You see it with folks who dont know much about the "newer" Fi models and how to restrict them.

FIM(FMI?) are the most known/reputable(only?) people making 33bhp restriction kits for sale to trade. If you're gonna restrict a carbed bike, chances are they have a kit for it. As i posted earlier....putting washers in the inlet of an fi bike to my mind will tend to make it run rich, but i could be wrong, perhaps the throttle stop helps avoid it getting too rich.

Its def far easier/quicker/easier on the engine to just change the ecu, but if the guy who did the job didn't know that...well.......

As i said, my advice would be to call the dealer and explain what you've learned and see what he says, and if he thinks its the same thing then bring it to the dyno to check if he's right. He might be..he might not....

Makes sense :smt115

[kcowgergmm]

i am glad in the Us you can have full power from day 1 but it might be why all the idiots kill them selfs within the first year

[Stu]

Check Carbontek for a free dyno run on Saturday morning. It's near you.

[Uberloinvongenchler]

the bike only goes as fast as you make it...restricted or otherwise :rolleyes:

the restricted bike feels dull. two stroke 125's for ftw!:D

[wknight]

Well I can't answer your question completely as I am running in my Restricted SV650 so I can't do more than 5500 revs, but compared to my Bandit 650 it has a lot more get up and go.

What the dealer explained to me is that the restrictor only kicks in at the higher revs, so at the bottom end it behaves just like a normal bike.

[Uberloinvongenchler]

taht's probably right, but i bet the bandit is a lot faster bike -certainly consdierably more powerful in standard form, no? and waht r u on about 'get up and go' - the sv is slow below 6k, standard form as it is! ( i really do have perverse sense of speed - i was bored with the sv before i ahd it restricted - too easy to ride probably :-p) anyhow, you dont get much more grunt up top anyway so you arent missing out (while it's restricted).

my advise would be live a bit and ******** to the restriction. but rememeber if you're having fun, you're probably doign something illegal -hell if it wasn't necessary to reproduce i reckon the gov't wud tax us every time we had sex!

where was i --->

equivalently sized in-line 4's tend to win in the power stakes. the ducati 749 was put down by What Bike? magazine on account of the fact that jap 600's wud kick it's ****. :pale:

[northwind]

taht's probably right, but i bet the bandit is a lot faster bike -certainly consdierably more powerful in standard form, no?

It's a fair bit more powerful, but it's also a fair bit heavier...SV's faster 0-60 and over a quarter mile. Absolute max speed, the new Bandit has the edge I think but they both take all day to get there :)

[wknight]

You don't have to remove the restrictor to have fun, I want to live to see my next paycheck as there is a lot more I want to get out of life

I am not one of the idiots who thinks its fun to do a quick overtake and almost get themselves wiped out in the process

Somebody I rode with got killed recently on his bike, not because he was doing anything wrong, but it looks like some idiot, this time in a car, was probably going too fast and came around the bend to find someone in the road waiting to turn. He couldn't stop, hit the cars which threw them into the path of the bike

Remember, its not just your life its other peoples as well. We can all have fun but its important to be responsible for your actions and remember the consequences for everyone of what you do, which means family, friends and other innocent people who were there at the time

[oldjack]

Wise words wknight.

Uberloin, the reason for the restriction is to prevent you killing yourself or somebody else while you still know everything, which you clearly think you do. You have "a perverse sense" of you own ability and immortality,:reaper: good job I'm not your dad, sonny boy[-X

I'm only glad I and my family don't live too near to a little village east of Cambridge !

[fullstop102]

Uberloin.

As already stated it is there to stop you killing yourself. I am not a power head but I am glad I didnt have more than a 125 to learn on and have after my test was over. 2 Wheels will always be dangerous and you need to treat it with the respect it is due.

The law is a fantastic way to let you get on a bigger bike without killing yourself at the first throttle pull. There has been suggestions of keeping people on 125's for a few years but I think the way it is, is just fine.

Please take care because we dont want to see you under a car.

i don't see how im any less likely to kill myself on a restricted bike. i thrash it a lot more than i thrashed the more powerful biek because i respected it more. :S

also, i'm not that brilliant at riding a bike. and i always find my self irritated by finding out there is always so much more to know than one already does...

also, i don't think i'm immortal. i think i will probably die very soon. i don't think anyone should ride a bike if they are not prepared to accept the consequences of making yourself so vulnerable, which is fortuantely not possible if you die...

i don't fear death either. i fear more being made paralysed so that i coudn't kill myself afterwards to put myself out of the misery.

yes i agree that is somewhat perverse -hardly the "typical" attitude. one could fairly argue that you shouldn't be on the road if you don't fear death because you would ride wrecklessly.

i don't ride wrecklessly though...i just don't like my bike spluttering at 7k and feeling stiffled...

i have ridden worse and taken more risks on the bike since it was restricted. i know not of how to respect the power of the bike when i am bored with it already :S

perhaps i'll learn the hardway, as i probably deserve.:smt009

i think that arguemnt is more perverse. no law will stop someone from killing themselves. do you think a speedfreak 19 year old or 21 year oldf having passed DAS would be up to riding a gsxr1000? no... do you think someone who respected it's power but wasn't the most experienced person in the world could, probably...

m sv is still restricted. im bored, so ill use the school bus instead of being illegal. (no really).

would be nice to hear davido's opinion here. his sv restrictor came out one week after he got it due to being bored too, and he got bored with a full power sv after 3 months so he bought a gsxr600. he's still alive and hasn't caused an accident. it can't be purely fluke or drivers compensating, because I believe that you make your own luck. hope he enjoys living life a bit, as long as he isn't doing top speed runs.

[fizzwheel]

because I believe that you make your own luck

I agree with this.

But I also have the opinion that the law is there for a reason, even if you dont agree with that reason you should still respect the law. Or expect to get shafted if you break it and get caught.

I certainly wouldnt be crowing about what you might or might not do on an internet forum, Especially one where this kind of argument has been done to death ( no pun intended ) so many times.

Your bikes resticted, TBH your not doing yourself alot of favours by pursuing your line of argument, you've had one thread locked already, give it a rest eyh.

For the record, your just as likely to crash a 33bhp bike as a 70bhp bike, or even more. My 12bhp 125 was to fast for me when I first passed my DAS, my SV was and my GSXR still is. But if I had passed my test and got my GSXR for a first bike I'd be dead now. BHP has got nothing to do with it, its about your "road attitude" at 17 I thought I was bl**dy invicable and I drove accordingly, I wasnt in a position to judge what was best for me, I wouldnt listen to advice or reason from anybody I thought I knew best. A few close shaves, a minor prang or two and I learnt my lesson eventually. I still drive / ride fast, but I'm much much more aware now of how easy it is to get myself into trouble. The point I'm badly trying to make is that at 16 or 17 I dont believe your able to to do that, hence why the government put the 33bhp restriction into place, to protect you from yourself. Yes you might be a riding god, the next Rossi or whatever, but if you wanna go fast, take it on the track.

I've lost 1 good friend in a bike accident, another forum member who I had ridden with died last year in a bike accident. One of my best friends was knocked over by a car driver who was 3 times over the drink drive limit last year. YOU might not care if you die or not, but goddamit man the people you leave behind will. Spare them a thought.

[Rich]

Uberloin i think its time you started to look at the good points of a restricted SV and not the bad. I'm getting tired of hearing you tell us that how boring and slow the SV is compared to your RS50. If thats all you have got to compare it to then its not much of a comparison. I'm sorry to sound cruel but being 18 myself, i think myself lucky to have a chance to own such a great bike at a young age restricted or otherwise. Alot or kids our age interested motorcycles simple can't afford bikes. Instead of moaning about its lack of puff past 7000rpm change down a gear and just get on with learning how to master the art of riding!!! Amen!!

[Uberloinvongenchler]

yeha i agree to some extent - i am consciously aware that riding a bike screws my mum up, but then you doin't overcome a fear if you don't face up to it. but i guess if im not having fun on my bike, i can't justify riding it. except it can be kinda practical.

if you make your own luck which is working very hard to buy your bike and insurance all by yourself then i guess i am "lucky". - ergo it isn't coincidence or 'good fortune' that got me the bike. it was hard work. the point im making is that the law is not saving me from anything - i wouldn't be so irresponsible as to relinquish such personal responsibility. anyhow, each to their own. keep your bike restricted if you think you'll ride irresponsbly with full power. i know i canr ide responsibly with full power because my first 100 miles on my sv were with it like that and i rode pretty gently really,e xcelpt i enjoyed the upper range of overtaking grunt. i would trust no other 17 year old i know with that capability, i don't know many people as boring as me when it comes to not taking advantage of the opportunity to indulge in danger simply because it's there. i don't consider it self-discipline, it just feels uncomfy going super fast - i just LLOVEEEEEEEEEEEEEE acceleration up to say 65mph :-p

You can have fun with what you've got now, learn to ride it better, be faster in a corner, brake a little later, concentrate on finding the perfect line through your favourite set of corners. I regularly hop back onto an SV from my GSXR, the SV still leaves me grining. Its a big step down from 144bhp back to 70bhp, yet I still find it satisfying to ride, for the reasons above.

You can have fun on any bike. I used to love my 125, its all about your mindset and your approach.

you're absolutely right, being depressed sucks.

but corners are the most dangerous aspect. if you put a knee down on just about any of the corners i know round here (and for the most part even close) you'd be going about 3 times too fast. indulging in cornering where i am is more of a discipline -you have to try not to lean too much and brake too late. :-(

But corners, lead to the most fun and also the most satisfaction, nothing beats braking, changing down, tipping in, hitting the apex on the pefect line, winding on the throttle ( or pining it wide open ) and firing out of the turn, only to do it all again at the next corner, You dont need a full power bike to get enjoyment from that. You can do that on any bike. Corning is a discipline and one that you'll over time master. You dont need to get your knee down to go fast round a corner, corner entry speed, road position, correct gear and throttle control all make you fast waving your knee around in the air and hanging off like a monkey just distract you. Yes its a skill but not one you need for road riding IMHO. Watch the riders at the TT, their sliders skim the tarmac, if at all, yet they are some of the best road riders in the world.

I've been riding for 3 years I've done nearly 30,000 miles I still. cant get my knee down, I'd love to, but theres more to riding than being able to do it.

If your talking about going into corners 3 times to fast then your riding state of mind is all wrong IMHO. Again if you wanna push like that go and work hard, save your money and go and do a track day where you can really have some fun. People get their kicks from different aspects of riding. Theres loads of stuff you can do. Its not all about riding flat out all the time.

[Uberloinvongenchler]

what i meant was, i do go round corners pretty fast, and im no where near geting a knee down on tight bends and i woudnt want to. sometimes u ahve to swing out of the way for big coaches taking up half the other side of the road :-o

Yep you do. Again brings me back to road positioning, get it right and you'll still be able to have fun even with leaving yourself room for traffic coming the other way knicking your space.

[Catflavor]

Getting back to my original post ;) Interesting to see where this has wandered to... I rode my gf's bike again yesterday and found that the hesitation at 7k revs happens more when the bike isn't warmed up - which makes sense. Its still just noticable in 4th-6th when you've been thrashing the bike *ahem* for a few miles, but nothing to be alarmed at.

All in all the bike seems pretty fun restricted. It never scares you and if you change gear often and keep the revs between about 3.5-6.5k you have all the power you need to overtake and accelerate. Albeit gracefully rather than purposefully. Hehe.

The SV rocks. The forks are a bit poop compared the ZX-6R, but there's something about vee-twins which makes me forgive so much. I'd happily trade the ZX6R in for a SV1000. Hehe. That's actually saying a lot, because the ZX6 is the first bike I've had in 11 years which I can't fault on anything at all (apart from the flaky paint on the wheels, grr).

Thanks for the input again folks! Thought it would be good to give some feedback of my own, having ridden the bike again. ;)

Its still just noticable in 4th-6th when you've been thrashing the bike *ahem* for a few miles, but nothing to be alarmed at.

All in all the bike seems pretty fun restricted. It never scares you and if you change gear often and keep the revs between about 3.5-6.5k you have all the power you need to overtake and accelerate. Albeit gracefully rather than purposefully. Hehe.

The SV rocks. The forks are a bit poop compared the ZX-6R, but there's something about vee-twins which makes me forgive so much. I'd happily trade the ZX6R in for a SV1000. Hehe. That's actually saying a lot, because the ZX6 is the first bike I've had in 11 years which I can't fault on anything at all (apart from the flaky paint on the wheels, grr).

Thanks for the input again folks! Thought it would be good to give some feedback of my own, having ridden the bike again. ;)

well you're right about keeping the revs below 7k, but i find this very restrictive and you have to change gear a lot more to make adequate progress.

with regards to the overtaking, i am shocked at how inadequate a 33bhp bike is at facilitating this. It's all very well pulling off clever overtaking maneuvres in an endeavor to compensate, but this is not trouble-free biking.

I know it was comparatively a lot slower, but when riding a two stroke bike that you could obviously rev out, at least given the lack of outright acceleration, your reward was a nice dollop of oomph. with the restricted bike it's like building up to something and then nothnig happens -flat. (not really a surprise).

So, no it isn't really *that* much fun in my opinion, but maybe im not being daring enough. - i really find the suspension "soppy" too.

Still a solid workhorse. :-p

Also, I went to overtake a renault clio 1.4 and i only just managed to pass it somehow, and that was coming out of a 30 mph bend. - most embarassing and nearly resulted in an accident (i think it was being driven by some chav and loaded with his mates) who thought it would be funny to see what happened if i didn't get passed before the oncoming white van hit me. :s

Still restricted though so all you legal minds may rest at ease :-)

[monkey]

Uberloin stop being an idiot. I was just reading your old thread where the restricting sliders were going to "fall out". 100 miles at full power is exactly that-100 miles.That's not a lot. I'd stop whingeing and get on with it. I had to when I ran my new bike in.

I might have to have a go on an RS50 if they're so great, but then again I'd probably snap the little thing in half! ;)

[Uberloinvongenchler]

crikey how old is this thread!? :p i've done so many miles since then it feels like an age ago. i said 1000 miles, not 100 :S

also, if it's a new machine, then assuming you're running it in correctly, u wouldn't notice the restrictor for the first 1000 miles - 8k rev limit i believe...

speaking of mileage i do around 22000 miles a year. - that shocked everyone at hideout on their open day - a lot do around 3-4k a year -( that's lame) :-p

i was also assessed by an IAM police class 1 instructor who said my riding was exceptionally good - straight in for the IAM's test - i wish i believed that - im so critical of my riding all the time maybe that's why i get better quickly, still, not much fun being pernickety all the time! :-p

oh well!


rode down to chichester recently to burry my gran's ashes, went to portsmourth - i reckon the cops are a lil tougher down there somehow! :-p

regarding the weather, it was perfect pathetic fallacy - **** weather, sad event, gatso infested roads - quite an undesirable triad!
i kept out of trouble fortunately (i hope anyway)

im not happy with my front suspension. now there's a topic we cud all talk 4 hours on - suspension setups! :-)

oh speaking of the rs50 - it was really great when it was setup right - i went round some tight corners a lot quicker on that than on my sv, i miss its chuckability a lot :-( a bend i used to mange 52mph exactly round on a chicane now has to be taken at a mere 41mph on the sv :-(

hehe!

ride safe people :-)

[ThEGr33k]

33 on mine felt o upto around 75-80 from then on it took a while and it really couldnt crack 100 unless the wind was in favour or i had a tow (slip stream...).

Mine is a pointy model and when it was restricted it was just the ECU which had been changed as soon as 2 years was up it took me 5 mins to change the ECU back to the full power and off i went.

To those who think 33bhp is inadequate then you would be ringht if you was considering overtaking i agree with what has been said, it make overtaking a dangerous business! But tbh if you are wanting to have fun, take it to the bendy bits! Its great fun on the bends even without the 72(ish) BHP, so concentrate on that and when you get the extra BHP youll be a Daemon on the breaks and the corners.

Well thats my rant :p Have fun and take care!

[Uberloinvongenchler]

My local mechanic who im quite matey with complained when i said the sv was quick when you gave it some (when full power). He also refused to help me maintain it and use his rather amazing set of Snap-On tools unless he de-restricted the bike. He has a problem with this law and he's big so i didn't feel like arguing, and seeing as ive saved myself £200 in maintenance costs and learnt how to save £200 every 5000 miles i don't think i'll tell him that i put the restrictors straight back in afterwards... lol!!!

I reckon as long as i pretend to sound enthusiastic he'll believe it's still in its 'fun' state :-p

Anyhow, this discussion was already locked once so it's probably time to end it.

Oops i had the last word...:safe:

[barmy.biker]

it should state somewhere on the paperwork u get when u have the bike restricted how it was done. my brother has a 2001cbr600f restricted to 33bhp and it states that the bike is restricted by a throttle stop and washers in the throttle bodies to restict the fuel flow.

so id say check ur paperwork

[Rich]

This whole thread has kids saying that overtaking on a 33bhp SV is dangerous :smt102. This annoys me because i manage to overtake quiet easily on the 33bhp. It's all about preperation and knowing your limits, it's not all about opening the throttle and blasting off past someone on a blind bend.

I've been on rideouts and even been out with a few of the orgers and they didn't notice a difference of the power of my SV until i told them (unless they were pulling the wool over my eyes) Unless your overtaking cars past the speed limit your not going to struggle.

So abit of advice which will i think help you when you do get a full licence, learn how to overtake using 33bhp and learn how to ride using the 33bhp. I know alot of people think this laws cr@p but im making the best of a bad job and having a hoot at the same time. Theres no better feeling than seeing someone on a 1000cc sports bike struggling to keep up with a 33bhp SV because they havent mastered cornering.

I think what they really mean is "You can't overtake in totally the wrong gear, like you can on a full power" :) I must have overtaken thousands of cars with my 9bhp on the 125, course, it couldn't go above 60mph...

Yeh you understand, its what you do with it just because its bigger doesn't mean it's as well ridden or as fast on the road!!! ;)

[Uberloinvongenchler]

I'm getting tired of people quoting "kids" when this is also the belief of someone who has done a damn site more miles over a much greater length of time than you. And no i am not simply regurgitating what he is saying "33bhp is dangerous". no it isnt in it's own right. I know how to ride the bike using only about 15 of it's horses because i can't afford to run it over about 5k revs for the most part. for the other 5-10% f the time, the extra accelration of the more potent bike will make a phenominal difference.

Also, I don't think it's much of an achievement beating a useless rider on a gsxr1000. there is reason why this bike is most popular - money + born agains...
i think it's incredibly vain to suggest that you've mastered cornering especially almost as a result of having the bike restricted and undermines a lot fo the credit i gave you for simply being responsible in the eyes of the law.

Another thing is, that i have compared my corner speed using the bike full power, and not. My cornering was a lot better and this is quite logical: a bike with greater flexibility at higher revs affords much better control and allows you to fire out of the corner faster too. The extra power also helps to pick the bike up if you are really leant over.

So, if as you say "you are making the best of a bad job", then please don't contradict yourself by making it out as if actually your cornering skills have become comparably better, than they would ahve been if youd otherwise had 70bhp. The factors influencing good cornering skills are multi-faceted and power delivery has a lot to do with it.

This is also a reason why a capped power plateau across half the top of the rev range is also destroying your abiltiy to learn to feed in power at an acceptable rate. it's no good simply pinning the throttle and knowing it won't bring much harm on a large sweeping bend.

If i consider the personal point that my area has corners which are divided unfavourably for such low power corning skill refinement then my "truth" informs me very differently: the really tight bends where 33bhp would be adequate for racing round is unacceptable due to surface conditions and visiblity.Thus if you use the corners here which are safe enough to rehearse and hone fast cornering skills, the you're well over the national speed limit anyway...which as we all know is also illegal...

When all is said and done, most legal eagles will say that the "low power = more danger" argument is falatious, and a red herring failing miserably to disguise the fact that kids want to go faster and faster...

Those commenting on this issue from the point of view that "the law is gods word" are missing the point too. Not obeying it makes us criminals - not simply thoughtful and responsible individuals.

So id say the liability of akid is down to your temperament. If you hack it round a corner too fast on any bike, you're going to come to harm - or others are...Having ridden several bikes, some restricted, some not, id say i was always the more responsible rider on a full power machine -less inclined to thrash the machine and constantly push the cornering limits to compensate for straight lines. and two stroke 125 racers - faster at cornering than any big bike in the tighter twisties, but most people of 17 use them to do just what they were intended for: thrash and crash.

I'm willing to accept that a discussion of the merits of taking the law into one's own hands are of course likely to generate varying degrees of controversy! ;)

I wasn't specifically talking about you uber, you seem to get easily wound up and then talk alot of mumbo jumbo when you feel things are aimed at you. I was only stating why do people or "kids" :lol: feel the need to break the law by unrestricting a bike when it's plenty enough power. Anyway i think everyones getting abit pi55ed now with this so i'd call upon a mod to lock this thread!!! :smt014 too much of this!!!!

[Uberloinvongenchler]

if you do say so yourself...:thumright:

[Giffer2]

Mine quite happily pulls well up to about 85 but then it's just a slow creep (Not that I'd exceed 70mph of course!) - So far I'm doing well, I've not changed the ecu for the standard one!

[dowdy01]

Got my 05' sv restricted in feb of this year from local bike shop!didnt no much about how they did it until came across this site!apparently they restricted it on the fuel inlet and the throttle!aas these are fuel injected thought it would have been far easier to restrict it by changing the ecu... which would make the bike run far smoother!!!I think! F I INTERNATIONAL is the company the restrictor kit is from........bogs down if u try and give it to her to hard up threw the gears, but yes gets to around 85 no probs then climbs SLOWLY and SLOWLY!yes u get the pic...

[Alpinestarhero]

I love my restricted SV :D :D

I just wanted to add something about saftey, and why the restriction is good...

When I first rode the SV, i realised that I lacked upper body strength to handle the bike properly. If i had full power, I know i wouldnt have stayed on the road for too long before getting lost in the nearest hedge. I've ridden about 1500 miles now on the SV, and I've built up alot of body strength. Its still not enough to really haul the bike about, but at least I dont feel like the bike is riding me anymore!

I'm sure now that I could ride a full power SV, although with just 1500 miles riding I'd still be a liability. This time next year, I should be good enough to ride even a GSXR competently!

i got the same restriction, gay really cos u can t get it off as easy when u want to change back to full power, my sv flys tho, gets up to 85-90 ( with only me on it ) really well and ive got it to 104 ( on private road of course ;) )

I didn't - I mean - don't.

if you're man-handling the machine and talking about lack of body strength then you obviously are barking up the wrong tree. I've seen kids of under 5 ft with no muscle adequately whack a golf ball 500yds at our local course and 250lb strong men struggle to get it over 300. Skill, control and subtle input are key. im not saying it isnt more healthy than riding car, but i doubt your bench press max will be significantly higher lol!

Secondly, (or perhaps more relevantly), why does full power mean youll get lost in a hedge? that tells me you know you wouldnt be responsible enough not to abuse it. so rightly, you are still riding a restricted bike.

I'm sure now that I could ride a full power SV, although with just 1500 miles riding I'd still be a liability. This time next year, I should be good enough to ride even a GSXR competently!


since how long have you been riding? at max id say a month or so with only 1500 miles on in order to actually be regularly honing your riding skills. i'm averaging 22k a year.

i have yet to meet someone who rides a gsxr comepetently at all, let alone after a year of riding. if a law is needed, its one to make riding a gsxr illegal until youve passed certain advanced tests. i saw an advanced instructor on one who id been talking to at a bike show who nearly fell off exiting the event junction as he failed to spot the gravel. hmm...

how reassuring - actually he was on a 'busa!

the ratio of people with bikes of such ilk out on the roads, to people actually skillful enough to utilise them is far from balanced.

yet its the same with cars - the marginal utility of a product is usually not down to its performance, but its image...

[northwind]

Yep, I've got no upper body strength at all, muscling an SV around isn't IMO the way to go.

[scoobdoo]

I hate to drag up old posts, but for the sake of completeness, i gotta add this! I just bought a 2nd hand 06 Pointy, it had exactly the same restricter on as catflavours, because I have a full licence and am old enuff I can legally take it off. It is the same model number and code as catflavours.
I`m pretty sensitive as to what the engine is doing as I`m riding and this particular restricting method just felt wrong. It would bog down slightly on open throttle and just didnt feel right. As mentioned in a previous post on this thread the throttle restricter is there just to stop the engine completely flooding and bogging down if you were to open the throttle fully. It seems a pretty agricultural way of restricting.
Anyway removal is fairly straightforward, but you need a bit of mechanical knowledge, take the airbox cover off and remove the air filter, you will then see two metal washers, thats your airbox restricters, take them out. Next is the throttle stop, you have to undo one screw that holds the throttle restricter in place, its by the throttle linkage under the airbox, you can get to it from the left hand side of the bike, i had to loosen the whole of the inlet (manifold/pleneum?) and lift it up about 3cm to be able to get a screwdriver in from the side of the bike and correctly alligned with the screw head, once you done that, unscrew the one screw the little metal restricter comes off.
I have read the thread and am not encouraging people to illegally derestrict their bike, but if you are like me, new to a bike model and want information on how to derestrict this particular form of restriction then there were no other threads on here that deal with it, so i hope i help someone!

[yorkie_chris]

This is a blast from the past.
but heres my 2p on it after about 6000miles on a 33bhp curvy;

I don't like the 33bhp law, for the purely selfish reason that more power is fun and the fact that I can whack the throttle wide open on many bends with no fear of anything untoward happening, this bit of the learning curve is something I'll have to do when the restriction ends. I also don't like the fact that it restricts what I can modify, as I like tinkering.
Overall I think its done me good as its good practice to overtake with less power, means you have to plan better, the same with cornering.
However I do think that 2 years is excessive, I'm doing about 250 miles at the moment and have ridden much faster tackle than the SV without ending up in a hedge. 6 months or a year on 33bhp would be more appropriate IMO
I would like the extra power, even if there is more risk of an off, but am not prepared to accept the legal risk. Fairly simple logic.

[plowsie]

Okay right havent read onwards from the post about where you say how they are restricting it. From reading a post about Girths thou he has just bought been restricted, that has some sort of throttle stop to restrict the bike. AFAIK the pointy is a ECU chip? On the Curvey it's washers somewhere in the carbs.

[yorkie_chris]

On the Curvey it's washers somewhere in the carbs.

One of 2 options:

Suzuki kit: Carb slides with holes in, dumps the vaccuum above a certain amount, stopping the slides from raising so far

FI kit: Washers on the inlet rubbers just after the carbs. £70 for 7p worth of washer.

Thats correct! And you're gonna see it soon enough!

Get about a 5th of the throttle. My Pointy 650 was ecu restricted, but i think the throttle restricter is a better way of doing it, espesically for a new rider, due to the fact the power is the same on a restricted and full power until the throttle stop comes into action.

[yorkie_chris]

Also doesn't mess up the jetting.

I want to build some sort of device, basically a programmable rev limiter, dyno the bike and set it to kill the ignition when it hits it.
No performance change up to the limit and can be re-set to account for getting the bike jetted right with a freeer flowing filter etc.
Will see what my electronics guru mate has to say about it...

[Stu]

The ECU restriction on the Pointy 650 doesn't mess up the bike at all - it runs absolutely fine .


You've... restricted... a. 1000? WHY!!!!!?????

[plowsie]

Stu have you seen the bike????
