Hi,Ken! I just found out that some of the Cosmo Colts had a variator on a Morini 101 engine.Very hard to get parts for.I think my Cosmo Colt has a Morini M02,but I'm not sure yet.Did you fix your brake problem and what was it? Also,I'd like to know what engine yours has?Does it have a belt driven variator or is it a Morini with a plastic fill plug at the top of the side cover on the right side of the bike,or does it not have this plug at all.Thanks for any reply.
