Default re: Motorized Bicycle Chain Noise

Since I first posted this thread I've found the identical problem on three other engines. That makes five total, two from one supplier the other three from different ones. This tells me it is probably a common problem on most if not all Chinese 2 strokes. This is a modification that almost anyone can make in less than an hour. The reduction in chain to case noise has been very noticable on all my engines so if you'd like to quiet your bike a little give this a try. These photos are a little better than the camera.
