I think thats wierd to. There might be something wrong with my trx250r(310) because even the regular TRX250r has more throttle response than the 310. Ill have to check that out. You can really feel the power though once it hits mid/top end power.

 

YEA, i WOULD CHECK THE JETTING AND MAYBE THE COMPRESION, I've rode 310 trx's and those thing rip hard

 

suzukis have the best engines and worst chassis and the 250s arent very reliable because of their age
