dave dix Posted March 31, 2009 Report Share Posted March 31, 2009 Hi, anyone got a manual or know the ring gap and piston skirt to liner clearance as i have located an oversized piston (ebay) and its winging its way over to me. I have got the barrel mounted on my old van norman boring bar ready to go as soon as the piston gets here and i can give it a good measure up. The barrel was on its second bore and the piston was standard!!! and it had a fair old rattle to it, its amazing that someone would put an engine together like that.

belldane Posted April 1, 2009 Report Share Posted April 1, 2009 Geez the motor must have sounded like a tin can full of nuts and bolts. If your Cota is a 70's vintage go to southwestmontesa.com. On the home page on the left hand side, scroll down to Repair Guide and you will find a full Manual for Montesas which you can download for nothing. If that does not answer your question, send Jared Bates (the owner of the place) an email and he will give you the answer. Regards Quote Link to comment Share on other sites More sharing options...
dave dix Posted April 1, 2009 Author Report Share Posted April 1, 2009 I will check it out, i have bored the barrel and have 3 thou clearance with around 5 thou ring gap and the motor sounds sweet. I never knew they had so much compression !!! Dave Quote Link to comment Share on other sites More sharing options...
