Default SV 650 Big Bore kits?

Anyone know who makes the 800cc big bore kits for the SV650 and where you can get them?
What sort of Power/Torque they give it?
Cheers
Liam

try jhs racing. They seem to be the experts. 80-85hp seems possible, but at the prices SV1000 go for- i'd do that instead.

Me three. Just seems a bit pointless to invest not inconsiderable amounts of money in making the SV650 a little quicker when there's a version of the bike with "the perfect mod" straight out of the factory.

But the SV 1000 is not perfect, especially if you like the curvy look. Plus Liam may have spent a fortune getting his 650 "just so". However having said that I guess someone will be along in a mo saying the bottom end will not take the mod and therefore it's only suitable for racing

I agree, and I didn't mean to suggest that the SVthou is perfect, but if you could do a perfect engine mod to an SV650, it would be to give it the performance and power of the SV1000.

I fully understand why people invest in their SV650s, but serious engine modifications can not be a good place to put the money, the gains are so small for the cost, and risk. Plus if the curvy looks are important, surely a TL would be worth considering (if you are serious enough to be considering a big-bore 650 mod).

800cc is too big, really... 700cc is quite doable, slight risk of terminal failure but it's not bad at all.

The only reason to do any of it on a road bike is that you like modded bikes or modding bikes IMO

if its just so you can go faster get a tl, looks just as nice as curvy and has cracking power to boot.

Yeah but a TL has about 130 bhp. Too much for some people. Me for one.

A BB 650 with around 80-85 bhp would be excellent and give the supersports riders even more of a whipping whilst looking standardish. Plus insurance would still be cheap, if you "forgot" to mention this mod. How would they know?
