I’m new on owning a scooter and learning on YouTube to how fix my bike, I have a lot new parts in it already, recently order new clutch , new variator with weights and it came with a belt and the belt was a lot bit smaller then the old one, put it on and there was no slack, belt was tight, thought it was good put cover back and crank it over, made this loud grinding noise even my kick starter lever move on its own and got stuck. I put the old parts back on and still has that noise, I’m afraid I broke something. I greatly appreciate if someone can help me find a solution before I buy a new camshaft.
