Thats great, there is a classified section for shit like this, rather than just digging up threads and fishing. What you do is put it in the parts for sale section, with a price and info such as willing to ship and shipped price or pick up only, if so location. Pictures help along with description. In this case "an H50 off a piece of equipment with a crankshaft nobody really wants on it, but ill still stick it on a mini bike site cause when you put "mini bike" in the listing its worth more. Good luck with your sale.
