I have an mc 16 but the tank leaks as it's got a small area that's peppered (i think it was a common fault)does anyone know if i can repair it and how?otherwise i'm up against it coz i cant find any parts for it let alone a tank but i have found brand new complete body work for peanuts. also what do mc16's go like? the bike was my brothers and it seemed to run o.k.many thanks Tim
