More power to SV650?
 

I'm having the older SV and I love the bike but... I think it needs bit more horsepowers so any suggestions ? I've heard about big bore kits are they worth money and are they reliable ?:smt104

Re: More power to SV650
 

cheapest way to increase your power.

Trade it in for a GSXR 750

for what it costs to reliably upgrade the SV lump. An all round superior bike would work out the most economical upgrade.

Re: More power to SV650
 

How much power do you want and how much money have you got?

Re: More power to SV650
 

Firstly, how doo

Secondly as above

Thirdly

How old is the bike?
How many miles?

The quickest and easiest way to get gains is:
- New air filter: BMC race filter or similar
- Good service and throttle body/ carb balance
- Everything adjusted and moving properly (Chains, cables etc)

If you are still going after more power, cam works like reversing the intake and exhaust cams or a set of kents and a set of 35mm minkuni flatsides (don't anyone has had any massive success with flatsides)*



*Do you research on these before diving in

Re: More power to SV650
 

I've heard about performance cam or crank shafts... That's about all I can offer

There's always the obvious but expensive roots of

Full race exhaust system,
Higher flow rate Air filter
Power Commander (injection models only I believe)
Bore out to 700/750 cc
Gas Flowing


These are all just terms I've heard and thought should get thrown in to the mix. I know absolutely feck all about the nitty gritty details.:-D

Re: More power to SV650
 

You mean 39mm flatslides I presume.

People who really know their stuff, like TWF, have massive success with them.

Re: More power to SV650
 

buy a TL or an SV1000

Re: More power to SV650
 

Thats the one YC.

I'm guessing you've not tried the flatslides yet?

Re: More power to SV650
 

Not on SV, they are mental on FZR1000 though.

Re: More power to SV650
 

Aren't TL's just a suicide trip on wheels?

Re: More power to SV650
 

No

Re: More power to SV650
 

Hell no

I know guys that bought TL's new and are keeping them.
TL's are wayward if you start taking the p*** (but that goes for most of the big bore sports twins).

There a good bit on the big twins in July's Ride mag about people riding them wrong

Re: More power to SV650
 

Abrupt and to the point, I like it. I thought they were renowned for being hard to handle and unpredictable. And thats why Suzuki ended them and brought in the much more user friendly SV?


Fair shout.

Re: More power to SV650
 

Some have stability issues, but then again so do some GSXRs, hell fire my GPZ500S could throw an evil slapper if you really really prodded it!
The owners don't help the reputation due to the machismo of owning "teh widow maker"

They had more power than the suspension could deal with at the time, sort that out and you've got a litre twin that handles as well as any other litre twin and better than most. Whether that's any better than an SV1000 with the same money spent on it is pretty much academic as it will come down to how good you are at twiddling adjusters.

Re: More power to SV650
 

Gpz's do throw good ones have seen the marks and bruises to prove it

Re: More power to SV650
 

My opinion on matter is you won't get a so-called "better" (yeah right, just bigger) bike like a GSXR750 or an SV1000 to have the same light handling toy feeling of the 650, and think tuning them makes perfect sense. But of course go ride other stuff and see if one will suit you.

I've ridden all sorts and given the choice I'd have a 650 tuned up to 90bhp and stick with it.

Re: More power to SV650
 

So how do you take a 70 bhp bike up to 90 bhp?

Re: More power to SV650
 

Pour £20 notes down airbox


Not to sound like too much of a patronising c*** but instead of asking questions why not go do some research, there is masses of material on here, svrider, BARF, WERA racing forums, TWF racing etc. What it sounds like you have is idle curiosity which should be sated by reading and learning then possibly doing, you'll learn a hell of a lot more random sh*t which will come in handy too.

Re: More power to SV650
 

YC spec list please :D

Re: More power to SV650
 

+1

Re: More power to SV650
 

flatslides, bump compression, mad cams, head work.

Why not go read up some posts by arctic donkey.


The fact that it appears to be just us 3 on the forum depresses me so I'm going to the pub!

Re: More power to SV650
 

Shame, that was just getting interesting

Re: More power to SV650
 

all 294 you've started!
Day for bored trolling

Anyways Chris

Re: More power to SV650?
 

Only if you ride it like a loon, newer machines are far more predicatable with a far more linear power delivery.

Re: More power to SV650?
 

I greatly enjoy reading the technical threads on here and am interested in power upgrades for my gentle and dainty 650, but for me that will be a very simple upgrade for my K3. Next April, my restriction is coming off!

I have looked at the Big bore kits with JHS racing in Bristol and was greatly impressed by the work they have done.

I have also had a quick look at Holeshot Racing, they seem to have some toys ready to go for the SV. Look here.

A quick google brings up these guys too, looks like they have big bore kits and other performance parts, but it was the spoked wheels that shone out for me. I don't know if they are a performance enhancer, but they look beautiful to me. Wire spoked wheels on my Sylvie would be awesome, if a bit of a swine to clean.

Re: More power to SV650?
 

hmm power .... to be honest unless you have sorted the suspension then theres no point ****ing round with the engine, you will need about £1k id say to get started on the suspension and few other bits unless use a bargain hunter like me

bigest change i felt was the cams, second was the pistons(and higher comp), and 3rd was the velocity stacks the other bits don't do much if any thing to be honest though iv only spent about £360 on the engine that includes 4 buss pistons, head gasket,cams,v stacks, other bits and bobs like honing 99ron fuel makes a nice difference now

and sold the other 2 pistons for £50

spent about £500+ on suspension

and just be prepared for your bike looking like this for weeks lol

Re: More power to SV650?
 

How much did you bump comp by, did you dyno it?

Re: More power to SV650?
 

70thou (or 7thou) i think zoran said (middle layer of head gasket)

not yet can't afford it atm (cars are expensive)

Re: More power to SV650?
 

I was quoted somewhere in the region of £2,500 to go to a reliable 85/90 bhp at the rear wheel from Steve Jordan who is considered one of the leading experts around SV's. I think you have to be fairly committed to remaining faithful to the SV to spend that kind of money on it, if you just want a more powerful road bike then your money would be better spent elsewhere.

Re: More power to SV650?
 

FASTER = suspension/brakes/tyres before anything else I'd say. Taking stuff off your bike you don't need or using a light weight subframe etc etc will be cheap. I know that's not what you asked but I'm skint

Re: More power to SV650?
 

keep the sv for winter and rainy days and buy a used blade 150+hp stops and goes round corners with out any mods and can be picked up for the price of making a sv handle & stop and getting a FEW extra horsepower,as there arnt any cheap ways of getting extra hp out of a sv
