Im new to the motorized bike world and so far I have been very successful installing the motor on the bike. However Ive run into/noticed a few problems while installing the chain. The cover that covers the sprocket on the engine will not come off. All 3 bolts are jammed up with paint and from a few things Ive looked at apparently that needs to come off? The other problem is that even tho I have tightened the clutch cable to specifications when I pull the lever the sprocket/chain (the one on the engine) will not turn, it will rotate a little back and forth but will not make a full turn. I looked into some details about adjusting the clutch and saw the whole flower nut lock screw deal but Im assuming thats for adjustments once the engine runs. Not to mention when I looked at the locking screw there it is stripped...straight from the factory. Breaking the chain is not an issue I can do that, Im good with bikes but have no engine know-how. So somebody please give me some advice before I lose my patience because I was super stoked about my summer project and refuse to give up but Im startin to wear down!!!
