A rare bird. I'm not sure I've ever seen one come up for sale in the north east.

FWIW, the stroke and the cylinder stud spacing of a CR80 Elsinore is the same but the transfers on the CR80 are much bigger compared to the MB5 and the case would need a fair amount of welding to seal the cylinder base. The mouth of the MB5 case would also need to be opened up to accept the lager CR80 spigot. It's doable, but not bolt on.

Quality advice! Thank you.

Mark, it is a '73.

And fwiw, I found these on Yambits that I like the look of.

Turning Wrenches / A few clutch questions
December 19, 2022, 02:41:37 PM
Greetings lads. I'm in the process of reassembling an RD350 engine. I'm at the point of installing the clutch and I have a few questions, if I may.

I noticed that the outer clutch basket has quite a bit of play re. the cush assembly. The basket will rotate freely of the drive gear, with maybe 30* of rotation. My experience is not with RDs but I'm of the opinion that any play is excessive. Could anyone shed some light on that for me? Is this fine/ normal or is it worn out like I think it is?

Second, to my embarrassment I found a stepped thrust washer that I'm not exactly sure the placement of. Is it between the basket and the case, or the between the 2 baskets? And can you enlighten me which way the step side faces?

And finally, in disassembling the engine I was force to drill the head off one of the clutch bolts. I think it would be prudent of me to replace them as a set but in my lackluster searching I haven't found any that I've been too excited about. So, where would you recommend I look for a set of clutch screws?

Thank you very much

A little late on this conversation, but just regarding MB5 suspension, YSS do a emulator type valve that will fit the MB5 forks. Which is fun, and does make a pretty big difference in how the bikes handle. More pertinent info here.
