ok, yea ive got a book and appreciate the link anyway. but im guna go ahead and do the build, when i took the jug off to yamabond it the rod had a good bit of play in it and like i said im pretty sure the bearings are wore out. and the machine shop ive had doing my cylinders isnt that good, i dont think the clearance in the same all the way down, when we did my friends last month we had a .020 yamaha piston and let them bore it to match, then it blew up an we went with wiesco and had them hone it cuz it didnt hurt the jug and when we were putting it together the piston was too tight. so im guna take it to the dealer they said the have a guy that does really good work. so that could be a factor too.
