So far, the only problem my new 4G build is having is a snapping noise and corresponding jerking feeling. I've never seen it do it but it sounds and feels like the chain is getting caught on a sprocket tooth. Like it is trying to jump off the sprocket. However, that hasn't happened yet.
The rear sprocket is pretty true. Not perfect, but pretty good. I'll get it perfect tomorrow. The tensioner roller wobbles. It came that way. I'm thinking that can't be good but I don't know if it could cause this problem.
I have checked alignment. I should call it 'static' alignment as the bike is on the center stand not running when I check it. Are there things that can knock the chain out of line when it's under a load?
I don't want to ride it very far while it's doing this. More information about the bike:
Standard 4G belt transmission on an HS 49cc engine (love the engine)
11 tooth freewheel sprocket, 53 tooth rear sprocket.
Walmart Murray bike maybe 15 years old
Any help/ideas greatly appreciated.
