Look at the sprocket and see if you have any teath missing, check the chain, and rear sprocket too, seems like a good idea.

ok figured it out somehow when i spliced the chain backtogether i went and put the wrong two ends back together which was leaving a longer space in the chain therefore making it skip which also chewed up the roller so ill fix it tommorro getting late thanks for that tip i would have torn the engine apart or used my spare much appriciated larry ca

Cool, once I had my sprocket on the back not centered and my chain kept getting tight then loose. It took me forever to figure it out and it was simple.
