Ok guys heres the run down i went and brought my dad a 99 yz 250 for xmas hes retiring 2012 from the county pd and i wanted this to be special. Ofcourse after picking it up for him i went over some little things and made sure its ready to go xmas day with that being said i had to give her a good ride to make sure the bike was running properly and man i was in for a suprise i had a hard enough time keeping the front end down, and the bike is all stock except for protaper handle bars. So i went out and had it set in my mind i need something to keep up with the old man now. So i picked up a real nice 01 rm 250 today that has alot of aftermarket stuff on it and agin got a great deal on it. After i got home and fired it up i kinda was a little disapointed it just didnt have that effect the yz does i can really feel the powerband in the upper range of the rm but the low end just is not really there. Like i said it has alot of aftermarket stuff like fmf fatty pipe and silencer boysen reeds and the suspension is worked. Is this just the nature of the best? Is it just a mid-top end bike? Or is something wrong? From what i have read guys seem to have a problem with handling the power of this thing but to me it just feels like its not hitting as hard as it should.
