Looking for help on a replacement flywheel for a 1966 MK2 Matador 250, the bike came to me in parts... crates of them, picked from the original 'restorer'. The flywheel in the pile is a FEMSA VAR 41-9 that is cracked at the rivets & has at least 3/16" rotational play. Anyone know what FEMSA part number flywheel should be on this bike? Suspect the VAR 41-9 may be another model, as I have a mod 26 in the pile of parts!
