i have a 250 ex and want to race it in harescrambles. it has a k and n filter, holeshots on the rear, renthal bars, and dg nerfs. ive never raced or ridden a 300 ex and i was wonderin wat i would have to do to make it run w/ them in a race. i dont want to bore the engine.

well a pretty big one..especially if the 300 is piped which most 300's that race are. there is a 40-50 some CC difference between the two but if i were you i would get a full pipe, and a jet kit and then just ride your race

um..either a sparks (not sure if they make them for a 250ex) a HMF, or what i have, a Pro Circuit..cant go wrong with any of those

i looked into all of those and sparks only makes a slip on so ive been debating between the pro circuit and hmf

the sparks is still an amazing pipe though

the 300 is going to have a lot more low end grunt especially with the clutch.

sparks does but why make the 250 aftermarket??? its almost pointless they can't run with too many of the other quads in its clas... waste of money to me...but hey whatever floats your boat man

yeah it wouldn't be too good for mx. but if you want to do something with it then go for it. its your money and if you don't think it is a waste and you enjoy then more power to you.
