Is there a difference between series 2 and 3 crankcases? The casing on my LI125 special are damaged, a crack in one of the transfer ports that goes through to the mag housing flange, a snapped casing stud that looks like somebody has tried to drill it out and snapped the drill bit off and some damage to the drive side bearing seat. I'm thinking of just buying a different crankcase as it will probably be cheaper than getting mine repaired. I've been offered an li150 crankcase but i think it's a series 2 the first two digits of the engine number are 85,
Thanks
