Moped = 1978 Motto Guzzi Robin
Issue = Recently replaced the rear innertube and now with the rear wheel back on the pedal chain skips off the rear sprocket when I start the bike and when I try to pedal it under way. It does not come ALL the way off, but it does skip. When I line up the rear sprocket, the tensioner, and the front sprocket they do seem to be out of alingment. I did nothing more than take the wheel off, leave it in my trunk for about a month while I waited for the innertube to come in, and then put the wheel back on. Any ideas?
