Trying to help a friend get his bike going. Needs a flywheel prt#21050-1110 and the sprocket that goes behind the flywheel prt# 12046-1072. Trying to find these items used due to the fact that he got the bike not running and the previous owner took it apart thinking it had an engine knock and we found out that the sprocket's bolts had came loose making a knocking sound, the flywheel got messed up in the removal. So if any one has a parts bike they want sell some parts from give me a yell.
