Default Re: Chain tension problem

You've checked the run out on the engine sprocket but have you checked the rear wheel sprocket. If it is not perfectly centered on the rear hub then you will see the problem you describe. Lift the bike so you can spin the rear wheel and watch for proper concentricity of the rear sprocket. That's probably where your problem is. Another place to look is the kit supplied chain. It is #415 and many of them have been found to have tight rollers, kinks and twists. Many of us replace it with a good quality #41 industrial chain available at Ace Hardware, Tractor Supply Co. and other industrial supply outlets. Let us know what you discover.
