Re: sprocket problems
i'm having trouble with my tension and sprocket as well. i got one of those spring-loaded tensioners but it only works properly in one direction and the chains rubs against a bolt which, imo is placed very poorly on the setup. based on the fact that my chain's tension is variable throughout one full wheel rotation i am assuming that my sprocket is not properly aligned. it must not be perfectly centered on the wheel.
does anyone have a spring tensioner on their motorized bicycle that i can see a pic of?
