i have only had my 250x for a few months and i put on 400ex rear wheels wich are 2 inches smaller then stock and went to a 1 tooth smaller front sprocket. my brother just got a used 2000 warrior with dg pipe and k&n filter. we raced and my 250x gets him on the street by my front tire up to his 4th gear then his pulls away because with my mods i have reved out by then. we switch bikes and the outcome is the same. how can that be? his is 11 years newer and 100cc's bigger is there something wrong with his or is honda just a king:devil
