Hi, I'm a newbie,
I'm been working on this bike for months, motorizing an old Schwinn Phantom. Had trouble with the chain derailing, and did damage. The got a new motor, and a sprocket drive from piston maniac parts. So things are working okay, and I got the chain tightened correctly with tensioner etc., about a quarter of an inch of clearance between chain and tire, but the chain is banging the whitewall and leaving grease marks. I think this is happening when the bike is starting, but don't know. Have a wide rear chrome rim, thinking about maybe I should change that, these are never real true. Also thinking about pulling the drive sprocket, on the motor and shimming it out a bit? Any thoughts. Please I need help
