HI, recently met a girl, (yeah its one of those stories) she has a 03 ttr125 LE and has neglected the hell out of it. insert me. It's bone stock shes never changed the air filter, been a year she said since she has changed the oil has not lubed anyhting other than the chain once in a while oh but she did manage to find a pink fuzzzy bar pad go figure im going to get elbow deep in her bike this weekend. since her bike has no oil filter im sure that all the free radicle metal particles roaming in her engine have done their work. since the clutch shares the same oil, would it hurt to put an engine detergant, and clean oil in the bike, run that around the block a few times to clean things up a bit, then change the oil again , would it hurt the clutch? also planing on opening up her air box removing the snorkle re jetting and cleaning her carb and installing FMF exhaust lubing all cables, axles linkage, chain etc etc etc.
