I brought the bike thinking it was a 349 frame with a 348 engine. I guess it is a complete 349. My wife has confirmed the engine number as being 51 H 00221 . It is a sidecar outfit! It was running spot on, and then started seriously back firing. I think we've traced the problem to being a worn keyway ignition side. I've got a couple of ideas how to fix it, but fear it will need a new crankshaft. Do you know where I can get a crankshaft from , also, anybody to fit it as i don'tI have the skills/tools to do the job. A picture of the beast. Thanks Loctite 660 for the worn keyway works a treat Quote Link to comment Share on other sites More sharing options...

ErikMyhre Posted January 24 Report Share Posted January 24 Hello Gents, I have a Montesa Engine ( i am pretty sure that it is a 360 Enduro motor. Can anyone identify the year and model? the number on the engine is 67M0201 I am looking for a rolling chassis to go along with this engine. Thanks!

I think you are looking at a 1978 or 1979 360 Enduro 👍 sweet bike, I bought a 66M in 1976 but that is the 360VA Motocross version 👍 awesome bike, wish you had an engine for that one, I'd buy one of those in a heartbeat.
