everytime someone has motor trouble people say ,leak down test,crank seals gone,check rod end play,bearings gone. you got the cyl off,check for deap scratches and chips missing if none,install new rings and gaskets and go. does anybody here ride a less then perfect bike.if you look at my 500 you might be able to tell where i rode last month. every bike posted here gets the beautifull bike comment.does anyone ride a dirtbike. rings and gaskets used to be in everybodys tool box. mine smokes a little to much,crank seals maybe, but still runs like crazy. tear down someday,but not in the near future. dont enjoy it looking at it ride the d**n thing and have a good time.
