April 13, 201016 yr Hi all im new to this forum. and in need of some help identifying a montesa project i have just bought? the engine no is 51m8743 the frame reads 51m2004. should these numbers match? also the tank cover says 349 under the many coats of paint! any help would be great and pics of bike in orginal state! thanks in advance!
April 13, 201016 yr Author yep ishy it as 2 of them badges on tank cover! was that pic supposed to link to montesa site?
April 13, 201016 yr your best post ever John. rick, with 6739 units difference between motor and frame my guess is that you have a Cota 348 motor in a 349 frame. Look here for ID photos: Montesa Web You could also email Jared at Southwest Montesa for help with parts and ID post some pics to help us ID it Martin Edited April 13, 201016 yr by Martin Belair
April 14, 201016 yr Author right i have had a go at uploading some pics! a have looked at a few websites trying to id it? where all 348s 51m? did the 348 have a different frame to 349 as mine as rear frame loop
April 14, 201016 yr Author and more! this is showing a bracket that as been chopped off im thinking its for hanging exhaust!
April 14, 201016 yr Hey Rick, that looks like that old bag of 2hit I threw in't cut by't gas works More like fished it out & weighed it in for scrap. Frame's a 348, there are a few different versions of the 348 frame, some have tube 'ears' either side of the mesh stuff, acts as casing protectors. You're correct in saying somebody has cut the exhaust bracket off.
