Hey everyone i`m new here its my first post and not a real simple one either. First off i have have a real solid 01 rm125 praticaly nothing is factory down to the bolts (race preped and all rebuilt and broken in) thats been sitting in my basement collecting dust since 03 i love the bike but i`m 25 now and been out of the sport for a while, i`m basically asking if there`s anyone out threre that has swaped out a 125 for a 250 engine, i have alreadly searched but have not come across much info except for the obvious exhuast and engine brackets but i`m looking for a more detailed write up. Also i understand that it would be easier to just find a 250 but i`m i`m not a real tall guy 5.6" 150 lbs soakin wet ,i felt real comfortable on in it and also i have a lot invested in this bike beside`s the engine so any info would be appreciated or websites that might steer me in the right direction....Thanx Adam
