hey all, i'm new to the whole SV game, im looking to get a 650 to use as a track bike, not looking to enter championships either its just to have a bit of fun, so theres carb models and injection models, i know there's less bhp to a carb model, but is there more you can do to a carb one than an injection model? is its a case of re-jetting the carbs?
any advice would be great :)

An injected bike can be set up on a dyno and have a custom map applied to it controlled by a computer to make sure it's making the most if it's induction, exhaust, fuel quality, etc,etc.

A carb has some screws and nozzles you can fiddle with.

I'd go for FI every time.

That being said, the SV650 is not a bike you buy and tune to produce more power. If you want more power, just buy more powerful bike. There's plenty about.

thanks for the advice, im mainly going for a sv to get a naked version i find it more comfortable, also looking at prices carb models are cheaper and im not looking to spend much just in case the worst happens

That should read "when the worst happens"...

Curvy power can be increased by fitting pointy cams & getting a modified woodruff key to advance the timing by 4 deg, that and a filter kit, plus a re- jet and maybe an exhaust can release some extra gee gees at minimal cost.

You don't want to go too far without risking engine problems

Hardly worth the agro with the engine work, buy a curvy, carb model, stick some rubber on and enjoy. Spend your money on up grading the rear shock and the front end. Simples !
