The chains are loose. The one from the output drive sprocket to the 17 T jackshaft sprocket can be tightened by sliding the engine along the holes in the mount plate but I hit the end with one of the bolts so I can't move the engine further toward the handle bar unless I mod the mount plate and drill new holes. This is a SBP 4 stroke shift kit.
Also did anyone blow out their nexus 3 internal hub. I don't think they are designed for motors.
