-
Greetings. I am new to the forum. I grew up riding a YZ-80 and recently picked up a 1980 RM 250. It is mostly complete, but the left side engine crankcase is broken by the clutch actuator. The previous owner screwed a metal strap into the crankcase and it almost holds things steady, but the clutch feels horrible as a result. From web surfing, it seems that when the chain comes off, this housing was frequently broken.
I have started looking for a new left side crankcase, but so far am coming up empty. I read somewhere that the RM 400 crankcase is the same. The Suzuki part number is only one number off 11300-40821 v. 11300-40831 (that is the whole assembly). I might be able to have it welded, although a weld fix would probably require machining at the end of the day.
Anyone have any ideas?
Thanks! -
