I've done several builds with these kits and the chain/sprocket part has been, by far, the most troublesome. The chains are absolutely unforgiving as far as alignment goes. If they are not perfectly aligned between the two sprockets, the chain gets thrown off the wheel sprocket and ends up jammed between the sprocket and the spokes. Chains are heavy, and require frequent lubrication and adjustment. They are noisy and have hundreds of moving parts.
As much as Harley Davidson insists on clinging to 1950's technology, even they have recognized the advantages of belt drive. What about this?
