andrewb Posted January 24 Report Share Posted January 24 Hi, It's been a while since I last posted. I am finally getting round to rebuilding my Cota 349 1979/80 (an early one). It's only been stripped and in boxes and drawers for the last 12 years, so I'm moving quickly on this one🤪. Can anyone let me know the correct piston ring gap for the standard bore please? The bore is good, not oval, and has hardly any wear, so I am just putting new rings in. I have the new rings but wanted to check the gap before assembling. If I remember I'll post some photos along the way. I've already rebuilt and re-spoked the wheels, frame powder coated, new shocks and forks rebuilt and fitted. Going to have to do the forks again though as I've realised the previous owner missed a couple of parts out. So I'll be ordering new internals. Here's a quick peek at the story so far (if you're interested). Thanks! Quote Link to comment Share on other sites More sharing options...
majesty Posted January 24 Report Share Posted January 24 Hi, Sorry I can't help but perhaps a quick whats ap message to these chaps might provide the answer. They seem to stock quite a lot of parts for all models https://clasicaslegendarias.com/shop/en/153-montesa-cota-349?page=8 Quote Link to comment Share on other sites More sharing options...
andrewb Posted January 24 Author Report Share Posted January 24 Thanks for the quick reply Majesty! I have a list of parts for the company you mentioned, so I'll give them a try. Thanks again Quote Link to comment Share on other sites More sharing options...
nh014 Posted January 27 Report Share Posted January 27 Standard piston ring end gap is 0.20 to 0.35 mm (0.0078 to 0.0137 in). Quote Link to comment Share on other sites More sharing options...
