I have the entire 80cc kit installed on a roadmaster "elevation" 26" bike and I'm trying to work out some bugs I have ran into. I can post pics if need be but I figured I would try to explain my issue. The chain I have is walking sideways enough on the bottom of the rear sprocket to then click back on and almost come off the sprocket. It seems like the rear sprocket may be mis aligned or the tensioner is having issues guiding the chain on but is there any guides for getting your chain lined up properly or methods for making sure everything is where it needs to be?
