250 vs 300 ex

[2strokerider]

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.

in harescrambles..it all depends on teh rider..i would know i race about ten of them a year

[2strokerider]

wat kind of power difference is there between the two

[m250r]

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

[2strokerider]

wat kind of pipe would u recomend

[m250r]

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

[2strokerider]

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

[m250r]

the sparks is still an amazing pipe though

[2strokerider]

wat is the power going to be on the slip on to be compared to the full system though

[m250r]

do a search in the powertrain forum..you will find a lot more information there than i can give you
