sunny Posted October 31, 2010 Report Share Posted October 31, 2010 I had an ad on the local online classifieds looking for Montesa Cota's and someone replied with the offer of what I think is 349 Montesa Frame but more importantly a 348 motor which was what I needed to fix the Cota 348 that picked up the is summer that had a broken kickstart shaft and missing counter weight flywheel. It also came with a a spare 348 tank/seat. I think I will try and sell everything minus the motor (it has been powder coated). Are there any other upgrade parts on the 349 that swap over to the 348? Do I need a special puller to seperate the cases or just heat and tap apart? Sunny Quote Link to comment Share on other sites More sharing options...
vintagecota Posted October 31, 2010 Report Share Posted October 31, 2010 (edited) 349 is a better frame, 348 a more tractable engine in my opinion. The 349 air forks are an upgrade. I'd be putting the 348 engine into the 349. The only thing holding the case halves together, after the mag and clutch and shifter, and flywheel and kicker etc etc is off, is the press fit of the 2 main bearings on the crankshaft. If I recall correctly, the right side of the engine should be down. Maybe get a helper to hold the engine up by the left side case and then tap on the crankshft, no heat. You won't be able to hurt that side of the crank any more than it is now.... Edited October 31, 2010 by vintageCota Quote Link to comment Share on other sites More sharing options...
sunny Posted November 1, 2010 Author Report Share Posted November 1, 2010 Do the air forks have valves like you would find on a tire? If so.. I think the original 348 has them all ready. I think I will pick parts from the new parts bike and finish the 348. Quote Link to comment Share on other sites More sharing options...
vintagecota Posted November 1, 2010 Report Share Posted November 1, 2010 Yes, they have stems and Schrader valves like a tire. Late 348s had them too. There's rubber caps to go over them so you can't see them. Quote Link to comment Share on other sites More sharing options...
