Engine mods, need advice

Hi, this is my bike...
SV650s k3



I got 73HP at wheel now and for a few moment I thinked about changing my bike for a Triumph Daytona 675 but after checking the price and the insurance cost even if I spend 5k-6k on my engine
it will cost less then if I bought the triumph or any gixxer

I already got:
K&N air filter
Full Hindle Exhaust Systeme
Power Commander III usb
-1 teeth front sprocket
+3 teeth rear sprocket

Want I want:
- reach at least 90HP more will be appreciate
- got 754cc with bored cylinder, new crank shaft and knife rod
- change valve spring
- Change cam shaft
- and find a way to get a higher rev
- change the "fly wheel" (if I got one) :P

the only probleme is I can't find any of the part accept piston, crank shaft and knife rod

I found piston from Wiseco inc.
crank shaft and knife rod from faliconcranks

the only valve spring I found is for GSX-R
didn't found any fly wheel or cam shaft
and don't know how to get a higher rev

can some one help me modifying my engine or if it's possible fit another engine from a superbike in my sv :P

Thanks

they sell any and everything you would need

buy an sv1000s and keep a few thousand in the bank.

Higher rev is easy, SV400 CDI raises the rev limit. Cams too, there's allsorts of options there. I personally have no time at all for JHS Racing, but if you want to go nuts at an SV engine there's not an awful lot of options. Speaking to Steve Jordan's (or SV650Racer on this forum) and maybe Holeshot among others would be sensible.

But, before you even send a penny, check what sort of problems it'll give you for insurance. Mine is sitting pretty at 80bhp at the rear wheel without any heroic measures, along with suspension upgrades to match, and it's pushed my quotes through the roof- partly because so few places will quote me with replacement value. Most companies will charge you extra for the performance mods, and then only offer you the value of a standard bike- which is obviously taking the p if your engine work alone is worth more than the bike.

Don't even consider serious engine work on standard suspension, it's a total waste of money IMO. If you put a stock SV engine into a 675 chassis (using a magic wand, since it wouldn't fit, but bear with me...) I bet you a pound it'd be faster than a 675 engine in a stock SV chassis around the racetrack of your choice. Extra power's no use without the extra brake to stop it, and the ability to put it on the ground.

In fact, I'd honestly say if you want to go faster but keep the SV, don't spend a penny on engine work- go directly to serious suspension work, do not pass go. K6 GSXR forks, revalves to suit if need be, something like a Penske dual-action on the rear. Or as an absolute bare minimum, cartridge emulators in the front and a GSXR shock in the rear. The SV engine is a lovely package out of the box, and the suspension's not. Once you have the suspension and brakes working really well, then you can attack the engine.

TL1000 engine into an SV frame's been done, but it's a huge amount of work. The only real reason to do it is for the sheer hell of it IMO The sensible thing to do, if you want a large power increase, is to take your ignition barrel, unbolt it, and bolt it into an SV thou or TL... Or GSXR, is probably more sensible still

But, what do I know, I have an 80bhp SV with GSXR and Ohlins suspension, I'm in no position to lecture as to not throwing money at an SV. It's very close to my ideal bike, to be honest. I don't like heavy bikes, massive power, IL4s or anything that's too good And I really like messing with the things.

Just remember, no matter what you do it'll never be a Daytona.

Thanks gixxer1300r

but they don't have valve spring or fly wheel I'll send and e-mail to know if they have it or not..

kwak zzr:

I already spend around 4k on my bike, I don't wanna sell it to do it again on another. but if I can fit a sv1000 engine on my sv650 thats may be the job....

anyone know a place where they do engine swap??

Twin Works Factory have stiffer valve springs, JHS probably do as well- I know they used to, with the Stage 3 cams. But that's something you fit if you have to, not because it gives any other benefits really. Fly wheel... Some people lighten the stock one, but I'm curious what you expect to get out of it- faster engine pickup of course but most likely, reduced drivability for the exact same reason, less rotating engine mass.

I bet you a pound you'd be cheaper having Spondon build you a frame to fit a TL motor into on SV geometry than you would having someone do the swap for you. From memory, it means major frame modifications, and also quite a lot of work to get round clearance problems at the front.

You'd absolutely, definately be cheaper getting a TL, that's for sure... I'm sort of curious where your £4000 has gone, tbh, I see the lowers of course- Poly 26? And powdercoated or anodised standard rear controls, the Hindle and PC (plus setup) and so on... Do you have secret suspension mods? Or were you including the value of the bike?

Northy I think that might 4K US Dollars. Look at the reflector on the front forks I don't think thats a UK bike...

[dirtydog]

I was wondering how long it would take for someone to notice that

yeah, also anybody noticed how it appears to be a black frame and its a K3?

You know, you're clearly right
