Hi, The only thing that could have caused your clutch to stick is tightening the sprocket nut in gear causing burres on the basket not allowing clutch plates to move smoothly, highly unlikely. Putting the shifter rod in a different position will not affect your clutch at all but you may not be able to get your boots under the shifter. I don't think anything is wrong with your bike, that wasn't wrong before the conversion, other than sticky clutch plates from sitting. Start it up, let it warm up to thin the oil, put up the kick stand pull in the clutch and put it in gear. If you are worried about the bike taking off rest the front tire against the wall of your garage before starting. Good luck and let us know how it turned out
