Off center bicycle motor sprockets.
O.K., a quick one here.....
How many of you have had trouble getting the sprocket that came with your bicycle engine kit centered on the wheel?
Not side to side run out, but centered so the chain remains one tension as you move the bike?
Norman mentioned that some of the holes were drilled off-center before. I had trouble with both of the kits I built- never checked the hole for accuracy, I always assumed it was because I used coaster brake wheels and the hole in the sprocket was larger than the hub, thus I never got it centered....even after what seemed like a hundred tries.
Let's hear it!
