cornishtwinspring Posted March 20, 2017 Report Share Posted March 20, 2017 Its def a 349 prob an 81yr model, released as celebration of their 1980 world championship. As already mentioned pretty much all of the bits are available for them but the motors are a law unto themselves. 1 Quote Link to comment Share on other sites More sharing options...
netley Posted March 21, 2017 Author Report Share Posted March 21, 2017 Yes I'm definately interested as long as the engine is ok as it seems they aren't exactly straightforward to rebuild. I've never really got on with left foot braking on my Bultaco being used to Japanese road bikes. I may prefer it but can't keep both. If I get it I will probably be bombarding the site with questions. thanks for all your input. Neil Quote Link to comment Share on other sites More sharing options...
brewtus Posted March 21, 2017 Report Share Posted March 21, 2017 Well, it does say 349 on the side plastic. Have fun with it if you get it. 1 Quote Link to comment Share on other sites More sharing options...
netley Posted March 22, 2017 Author Report Share Posted March 22, 2017 Cheers people. I'm picking it up a week Friday Quote Link to comment Share on other sites More sharing options...
netley Posted April 1, 2017 Author Report Share Posted April 1, 2017 Hi, I picked the Montesa up yesterday and I have a few questions. The frame/engine no. is 51M22445 there are definately not any lower frame rails. After a cursory glance it looks like the bash plate is just hooked on at the back of the engine and doesn't give any rigidity. Also, are the forks standard, is the fuel tank road legal, it looks like fibreglass, and is the carb original ? pics to follow. Quote Link to comment Share on other sites More sharing options...

feetupfun Posted April 2, 2017 Report Share Posted April 2, 2017 Carby and forks and frame look right for a 1981 349. Front wheel having a gold rim means it is from a later bike. I'll have another look at it 1 Quote Link to comment Share on other sites More sharing options...
feetupfun Posted April 2, 2017 Report Share Posted April 2, 2017 Front wheel looks like a later model Montesa Cota that has a Honda hub (from after Honda bought part ownership of Montesa~1985 maybe) 1 Quote Link to comment Share on other sites More sharing options...
netley Posted April 2, 2017 Author Report Share Posted April 2, 2017 Here's hoping the Honda hub is an improvement Quote Link to comment Share on other sites More sharing options...
feetupfun Posted April 2, 2017 Report Share Posted April 2, 2017 The bashplate is not the original one and doesn't fit very well. I wouldn't worry much that it is not working as a stressed member with those rear mounting clips like that. The motor castings are easily strong enough to act as the frame member as long as the engine mount bolts are kept tensioned and you are not planning to ride at world trials championship level or race it over the jumps on a modern MX track. 1 Quote Link to comment Share on other sites More sharing options...
netley Posted April 2, 2017 Author Report Share Posted April 2, 2017 I'm a complete beginer so there's no danger of that. Will the plastic tank ( repaired with fiberglass) be road legal ? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted April 2, 2017 Report Share Posted April 2, 2017 Keep the spokes tensioned nicely with that hub because they are known to crack around the spoke flange if the spokes are not kept tensioned properly. I'm not sure if it is the Honda hub from that photo, but the later model Montesas had them and it looks like one from what you can see. 1 Quote Link to comment Share on other sites More sharing options...
feetupfun Posted April 2, 2017 Report Share Posted April 2, 2017 UK Montsas usually have an aluminium tank inside a fibreglass cover. I'm sure you could get one of the aluminium tanks and use your tank to make the cover from. Sorry I don't know the road-legal status of fibreglass tanks in the UK in 2017 Quote Link to comment Share on other sites More sharing options...
