if the sv650 aint fast enough and does't handle you should have got something better in the first place,a sv1000 is faster and got more horsepower but everybody i know who has had one has had major trouble with the clutch drum and have been glad to get shot of them,so i would recomend a blade or a r1,or if thats to much hp then buy a vfr800 and get the best of both worlds being a 4 cylinder and a v

Instead of telling the guy what he's already said he doesn't want to hear, why can't we just answer the bl00dy question? Or keep quiet. Maybe there's other reasons why he likes his SV and wants to keep it! Look at people who will spend 10-20 grand restoring an old Norton or somesuch, they don't do it 'cos they'll end up with something better than the new bike they could have bought with the same money. One thing about the forum that drives me nuts is the need to caveat your OP with all the responses you don't want, 'cos you can just see what's coming.

Agreed. Most people think I am mad for spending what I have on the SV, but the simple fact is I like the bike.

Would like Sarah to step up from SJ's and tell us the price list for those mod's she has quoted!

TB's have done lots of these and results are around 1-3bhp increase but generally shows an improvment right the way through.
Why the head bolts? Will they lift with the small bump to the compression that you can get away with?

Because it would make the forum a boring place if all topics were on topic, i think people are just trying to understand why.

My advice if you dont want an sv1000, put an sv1000 engine in it, makes even less sense ay lol.

It's not about being on topic, it's about trying to help the guy, instead of preaching a message he's already said he doesn't want to hear. He can then make his own decision on whether is mod is worth the money.

Maybe you were trying to understand why

but you were the only one who posed your reply as a question. Everyone else just told him to stop wasting his time and money and get a different bike.

Re: performance mods? 74bhp
 
for me the increase in performance is just the out come of a hobby that i love doing.....messing with bikes and mechanics im not the best by a long way i have only been spannering for about a year and a half if i can do most of the mods my self to bring the cost down then i will

thats what makes most of the mods i have done affordable like the cam swap cost me about £25 for about 2bhp

also it helps to have a GF as she buys me stuf :D like velocity stacks

For those that suggest the SV isnt worth it and doesnt handle, all I can say is you obviously havent ridden a well set up and well prepared one!. Stop being tight for a few moments of today and go and buy Decembers PB mag while its still in the shop and have a read up on the bike that Steve rode this season. It would be capable of running on the road if you had the budget. Yes it cost alot to develop both in time and money but shows exactly how capable the SV can be. Even if you take small elements from the total build.

Why not make the SV the best bike for you?. Personally the SV1000 has a worse chassis compared to that of the SV when well setup!.

Anyways cost wise your looking into around £2800-£3000 for the system, tuning work, cams, airbox mods and dyno time inc removing motor from the bike, stripping replacing gaskets, cotters, lightening and balancing crank. Costs vary though from bike to bike as you wont always know whats needed until the motor comes apart.

Its not about cost though, we have had customers spend £10k plus and you know what, they love their bike and thats what its about.

And what would that give you in terms of BHP and top speed?

I am genuinly interested and not be sacastic!
