So, I just got my 49cc 4 stroke belt drive engine on my bike, I put gas in it, and when I went to start it I noticed that the rear pulley had a pretty good wobble to it.

The shaft itself isn't bent at all so the wobble must be coming from the pulley, I took the pulley off and spun it and sure enough the wobble still persisted.

I guess I'll have to order a new pulley then :rolleyes:

I cant say that I am too surprised, as the kit wasn't all that expensive, here is the link for the kit.



As you can see in the video, the pulley wobbles about while the shaft stays true.

Anyone know a good place to but a new one?
