Follow-up. After about 5 tanks of fuel the starter gear bushing separated from the starter gear which in turn destroyed the oil seals on the crankshaft and starter gear. It leaked a lot of oil. X-Pro sent a replacement starter clutch assembly and crankcase oil seal but the starter clutch is too tall and will not allow the flywheel to seat on the crankshaft. After looking for more than 5 hours, I cannot find a starter gear that will work. Practically every 50-125cc gear is 28mm tall, this one is 24mm. It's starting to look non repairable without have a machine shop become involved.
