ok so i recently decided "im going to get a dirtbike and learn how to ride".. so i went out and bought a 00' kx125 with many mods for $500. it needs minor work (needs a tune up, fluid changes). i have recently changed the trans fluid and put a new irridium plug in it and did a quick clean of the carb. i also drained the gas in the tank as the bike sat for a few months before i bought it. it had a small oil leak on the front of the engine but i have fixed that now also.. I have a FMF header, Pro Circuit exhaust "silencer" boyessen billet aluminum clutch basket with a race clutch inside, I have Pro Circuit "dogbones" under the suspension springs, and all the suspension was replaced with race suspension, there are Renthal sprockets on the bike but i am not sure if that is stock equipment or not.. also has a Twin Air filter. it needs some good tuning for sure though.. opions welcome!
