Hi : 70cc HT - I can't figure out whats going on inside the engine thats causing the wheel + chain combo not to turn extremely smoothly. When i have the back wheel elevated to turn smoothely - it just doesnt spin evenly, like it feels like resistance coming from somewhere inside the engine (pretty positive its nothing bicycle related). This is my second build - my first one does not have this problem.
I'm trying to figure out, maybe if I need to grease something, what exactially is it and how much grease on that puppy.
