2003 SV650 HP/TQ mods?

[OTB]

Sorry, just read your original post and you said your options are limited...if you want fast, water-cooled v-twin, then you could also look at the 748... I had a pristine example this spring with less than 4k on it for less than $4k and it would romp all over the sv.. I know cause I have a 650 with a Penske shock and Racetech forks and some engine mods and a stock SV1000 and it ran circles all around both... but you said you wanted and SV and that's what you've made up your mind for.

OK...got it.....

As to your original question;
without engine work, you are pretty much limited to exhaust, filter/airbox, PCommander and a dyno map. These mods will yield about an additional 4-8 rear-wheel HP (at least on our Dynojet 250i that's what we see).

If this is a strictly track machine, you can coax an additional 2-4 HP out using MR11 or 12 race gas, but you'll need to drain and flush after each weekend.

After that, it's pretty much crack it open; there are high comp kits, stroker kits, big bore kits, cams, bored-out throttle bodies (which won't give you any more HP till you've done the other stuff).
