November 14, 201015 yr I picked up a load of Montesa parts yesterday. Some one replied to my wanted ad I had on the local online classifieds. I was hoping for something that would work with my incomplete 348 Cota but I think that it will not be the case. I have found some part # and serial numbers but not sure. The item I am most curious about is the 39M motor is this from a Cota 304?? Any help with ID would be appreciated. I have posted the photobucket address http://s266.photobucket.com/albums/ii267/9N11948/Montesa%20Parts/ Sunny
November 14, 201015 yr Author Thanks for the info. What about the smaller "motor" what do you think it is from? Do you think the 39M would bolt into a 349 Cota frame? Sunny

November 14, 201015 yr Hello it looks like to me the smaller engine is a 123 or 172 both are the same cases. Pity you live so far away because if you were going to sell them i would be interested in them.
November 14, 201015 yr 28M engine is a 123cc, probably from 1975. The 242 from 1984 was evolved from the 74cc/123cc engine of 1972. Nothing will fit the 349... Edited November 14, 201015 yr by vintageCota
November 14, 201015 yr The tank, small side cover and cyl/head assembly are from a 250 Enduro, about '74. The cylinder head by itself, carb and airbox and brake pedal are likely from the 242, as the appear very similar to my 200 parts. 242 carb is 27mm. The brake backing plates are 74/123/172/247 (110mm) the small exhaust pipe looks to be Japanese. Edited November 14, 201015 yr by vintageCota
