Ill look at the shift drum prob tomorrow or sat. That's my plan at least. Once some space is made. I'm going to do oil block off and maybe send cyl in for a port job. I live in an apt and my bike is at my parents so this weekend I should get it torn apart. I don't know how well the guy that rebuilt it skills are so it's hard to say how well the engine is put together. It's all good. Gives me a chance to learn more about the engine.
