i have a honda trx200sx i just got.it starts,runs,and really moves.but,there is oil actually pouring out from the exhaust.any ideas before i order the parts.also,where do i locate the engine code on the motor?this thing has had a change over on parts.only the frame and body are a trx200sx fourtrax.it has a kickstart,6-speed engine/tranny,pro link swing arm,extended axl,rear disk brake,larger rear adjustable shock.its worth fixing.i dont know what motor it is untill i find the engine code.ANY help would be appreciated.
