Ok guys, Rode yesterday after a good preflight, and noticed just now that the drive chain from engine to rear wheel was tight. So I readjusted the chain follower and got the correct tension etc. I was spinning slowly the rear wheel and watching the chain and it would go from tight to lose. What the heck???? The dropouts are in proper position so what gives? The gear off the engine could not be warped could it? Now I did not check the rear sprocket so could it be out of alignment? I will check that but hate to ride thinking I could toss a chain. Ok that is the problem, answers please. lol Thanks gphil
