hello everyone, as you can see, im new to this forum.
jus a quick Q...
im planning to buy an SV650 '07 plate this week, but as im 17, i need it restricted.
ive been to a good 4/5 dealers and they can get 2 types of restrictor, the official suzuki ECU restrictor (£340ish) or the FI international throttle stop/intake washer type things (£150ish).
obviously i want the cheaper option, but say if i had the throttle stop put on it, would that limit the revs? as the revs and position of the throttle are directly linked right? therefore id never be able to fully use all of the rev range, and it would do my nut for the next 2 years :mad:.
i really hope im wrong....
Look at the forum for a second hand ECU, go for around £50.
Don't get the FI international kit, waste of money.
Buy a s/h ecu off here, fit it you'reself, away we go! :)
Its only plug in plug out to swap ECU's.

i appreciate that's cheaper, but i wont get a certificate with it will i?
also ive read that intake washers affect the richness of the fuel or something? making the mpg alot lower? is that true for all SV's with them?
My FI International restriction used more fuel than the ECU restriction.
You don't need a certificate with most insurers, if they do ask, which not alot do, just get a dyno print out.
The certificate is a ploy by FI International to make you think you have a DSA/DVLA approved document for proof of restriction, which it isn't.
Am sure other will come along to bash FI International namely YC.

thank you very much. but id still like to know if a throttle stop limits revs...
No it doesn't, it reduces the amount of travel you're throttle has.
The FI international kit consists of 2 airbox washers and a throttle stop as you mentioned before.
The restricted ecu only replaces the full power ecu, which is the best option if you can find one.
Good luck with that, keep checking the for sale section..

'No it doesn't, it reduces the amount of travel you're throttle has.'
sorry i may have cocked up my explanation, but i know itll reduce the travel, but say the throttle was opened half way, the bike would only rev half way up the rev range right? so if the throttle's travel was limited, would it be unable to reach higher revs in all gears?
sorry
The throttle stop doesnt stop the bike revving out.
Obviously it won't rev out in the higher gear(s) because there isn't enough power to achieve top speed.
You need someone to explain why it doesn't limit revs, but I can tell you it doesn't limit revs.
I notice minimal difference between the ecu and FI kit, with no noticeable peformance changes.
Neither accelerates faster, etc.
So my advice, go for the ECU option, but buy s/h from here and fit it you'reself.

had a throttle stop restriction on my z750, was a PITA.. a full travel throttle with 33bhp limited ECU would be better..
just look on here/ebay for a K7+ 33BHP ECU, one will pop up for around £70.. maybe less if you get lucky..

oh ok, thank you very much :)
i think il jus get the bike restricted when i buy the bike from the dealer, and get it included in the price. jus need to buy the damn thing now.
What restriction mode are they offering?
Either?
If either, I would reccomend the ECU mode.
Easier to change when the time comes, and better mpg.

yeh either, but recommend (to me as im a 'skint nipper') the cheaper one.
ive read on another thread on here that you dont need the certificate that is supplied when you buy these restrictors first hand, only proof of the bike only having 33hp e.g. a dyno read out. is that true? i am trying to find some official dvla/dsa documentation to prove it.

okay, yet i read you need the certificate to send to the dvla to put on the V5 of the bike or something?

No you don't need to send the DVLA anything.. it's not marked on the DVLA database or anything, AFAIK.
APPARENTLY it's "logged" with the insurers (but this is coming from FI international, well enough said)... but i've heard nothing definate of proof... and never had any questions ever so idk
I shelled out for a brand new ECU (numpty) just buy it second hand if insurers need proof in event of an accident im pretty sure the part number is on the ECU that part number then given to any suzuki dealer will then come up as a restricted ECU on their system i got the cert any my insurers didnt need it when i insured my bike just that i was riding in the terms of my licence was all they said, if you want a certificate theres people on ebay who will ahppily knock you one up.
Let's be very clear about restrictions here. If you have a restricted license and you are riding a unrestricted bike you are riding without a valid license for the vehicle. The boys in blue do not take kindly to people doing that.
It also makes your insurance null & void because you don't have a valid license and all sort of legal repercussions are possible. The certificate of restriction proves to anyone who cares to know, usually insurance & the police, that the bike is limited to 33bhp & that you license if valid for riding said bike.
I am not sure if you have to inform the DVLA about power restrictions as their website only states that you must inform them of changes of capacity. Which if you think about it, makes sense.

The certificate of restriction proves nothing except that it was, at some point, restricted.
Capacity is defined as swept volume. For the bikes, it's for the tax. I could show you a 600cc that makes <33bhp. Or I could show you a 125 making >33bhp, and breaking the lesser known power-mass limit!
There is nothing in DVLA literature only that bike shall make <25kW net power and something like 0.16kW/KG (IIRC about the power/mass limit number).
FI int. are just a company, they are not officially sanctioned, regulated or empowered to remove all your money for a bit of paper.

Errrrm... why do you say that?! This is a thread asking about which is the best type of restriction, so surely it's obvious that he's getting it restricted no?

Not really true tbh. Sure, it might get a copper off your back if stopped at the roadside, but in the event of an accident they'd check the bike anyway (dyno run if the bike could still be put on the dyno, or check the restricted ECU/FI int (:smt019) kit was in there.
So Raf, I'm guessing by that comment that you believe that an MOT certificate is proof that a bike is roadworthy 6 months down the line? Well, it's not. Same applies here. If your insurer won't insure you without a "certificate", it's more likely that they'd try to wriggle out of a claim.
I am not sure if you have to inform the DVLA about power restrictions as their website only states that you must inform them of changes of capacity. Which if you think about it, makes sense.
Yeah, nothing on the DVLA sight says you need to inform them. As YC said, the capacity stays the same
In response to the OP:
Get a second hand ECU from here. They go for about £50 and take about 5 mins to fit (including time to stop for a brew ;))
