i bought a cheap YZ426F to get me back in to my bikes, i bought it having some problems but seen as im quite handy with a spanner thought id take the risk, anyways its throwing quite a lot of bluey smoke out the back, is the best thing to strip it down and inspect or will a compression test show the problem, i think its going to be either piston rings or valve stem seals, now i have more of a car back ground so if it could be anything else please tell me??
if the smoke was to be caused by the piston/ piston rings can the rings just be replaced or is it common practice to replace both at the same time??
next s it boggs down mid range, im thinking it may just be some shit in the carb but again if there is anything else just let me know??
cheers in advance
