I'm sorry to say it, but you need to keep contacting Zongshen America. They keep a nice inventory of parts, and the prices are great, but they don't have the best customer service. :roll:
Let's see a photograph of the end of the camshaft where you removed the cam sprocket. I want to see if end of the camshaft has been damaged.
Also, please clean up the dirty side of the cam sprocket, and post another photograph of it.
