had the chance to swap my 02 sherco and a 96 gas gas for a 03 250 pro,so what are the 03's like compared to a sherco, reliable? also what engine do you think i should get the 250 or 280 i like an engine that can plodder on in sections but with plenty of power to pull 4th up hills will a 250 pull 4th up hills? and alot of people said the 280's are really savage just to foget about them. and is it all 03's with the crap air box on? or should i just forget about the gas gas and get another 03 or 04 sherco 250 or 290? thanks colly
