[TRX_250r18]

just a little behind a 450 i have a bills pipe, v-force reed valves w/spacer, k&n, pro stock wiseco, works all around etc... so i just want to see your guys opinion on either a good part job with a cool head or just go to a 310 kit? money isnt too much of a problem its just im impatient.

310pv, it made my atc250r a absolute animal. it is so fast, words can't descibe.

i was thinkin the bolt on 310 fully ported kit but what kind of porting trx 7 9 or 11?

[deathman53]

depends if you want top end or low end power

I have a esr330 up for sale, $500, new gaskets and piston rings, crank bearings went bad and casued the bike to overheat and burn the pc off the head,but other than that perfect and comes with a pump gas dome and very high compression dome. you need to buy a piston.

There's no replacement for displacement. I can hook you up on a port job if interested, but not in a hurry. The porting type really depends on where you ride and your preference.
