Default Re: Hi my name is john, starting first build with sd stinger and shift kit

John, welcome to the forum. Sounds like an ambitious project for a first build. Good luck.

As for the rear wheel interference with the frame; are you sure the wheel is centered in the dropouts and not mounted at an angle? Some frames don't allow much in the way of rear wheel misalignment and require that it be centered and true. Does it have any wobble to it when you free spin it or does it contact the frame through a full revolution?

Whatever, you'll want to address that probelm before motorizing the bike. The rear sprocket must be aligned with the engine drive sprocket. If the wheel is off-center you'll have chain issues.
