performance questions

I have a 2001 250EX. Its getting the Web Cam, R/D Titanium valve springs, and a .40 over Wiseco piston...anything I should know?

I already have a Pro Circuit T4 pipe, Dynojet Stage 2 jets, and a K&N filter

I'll be getting a AMR Monster coil and Big Gun CDI box later on but not anytime soon.

A reputable shop is doing all the work so I should be good on that front...:)

cool cool

how many cc's is 40. over going to bump it up to?

[86250rrider]

the overbore does nothing for power unless old piston is beat and low on compression. now.........higher compression piston and cam, now your talking! i had an 86 quadsport 230 i bought new......cam,10.5 piston,open lid,rejetted,exhaust, it ran hard for a 230 for sure.it was a good bit quicker than the 04 trx250ex i have for the boss lady.

[03EX250]

the piston in 10.5:1 and the cam is a .330 lift on the intake and .303 on the exhaust, so i think im bumping up the compression a little;)

and hondariderdylan...im not exactly sure

[hondariderdylan]

well if you havent done it yet look at thumper racings 280 kit its only like 500$

[03EX250]

lol wish i had that kinda money...maybe next time, the .40 over piston on ran me 189 for a full top end kit

[hondariderdylan]
