Message: [QUOTE="tommyaus, post: 1384325, member: 119244"] hey, ive just recently got back into riding and bought a 03 cr250. after a few rides it started to leak oil through the pipe thanks to the bottom end seal gone and a wobbley crank. im gonna get the bottom end rebuilt and was wondering what sort of upgardes could i do to give it more poke down bottom, and if so would i have to do some piston work. the top has recently been rebuilt but havent had a look at it yet. i was gonna attempt to do the bottom end myself but i dont have the space. also what are some other good mod's to do, its got fmf fatty, powercore 2 pipe but got a shorty on the way. was thinking of boyseen reed kit too, are they worth it? any ideas would be great. thanks [/QUOTE]
