Re: What typically fails on a ChinaGirl motorized bike
That will go a long way to quieting the gear whine.
Another trick you can do it stuffing small, snug fitting blocks of rubber in between the cylinder fins. The fins do actually ring with every power stroke similar to striking a bell.
Quickly drag a screwdriver handle across the fins, from the cylinder head to the base gasket, to hear what I am talking about.
I also have dampened my clutch cover, but I used cardboard and black RTV silicone.
