    Ordered and installed a HS,Skyhawk 4 cycle kit. Could not keep the chain on the rear sprocket even though I adjusted it everyway possible....Bicycle-Engine.com sent me a replacement sprocket under warranty....Comparing the two sprockets side by side..it appears that in places the teeth are wider apart on the original sprocket causing the chain to ride up on the rollers and come off..Just wondering if anyone else has had this problem...
