Carl hi montesa cota 200 175cc ran from 1980 to 84 mh been the later model as far as i am aware the cota 200 frame number started 29m or a cota172 19m (74 to 77 ), i too have looked for a drain and have only found one on right clutch case but the frame prevents it from been undone ,, it is best to seal tank inside with a ethanol proof sealant look on ebay, as for mods ,mine has a lengthened swing arm and am thinking of fitting pegs further back and slightly lower,as for fuel when you say gallon is that 4.5 litre or 5 litres ? or a full plastic type fuel can ? as theres a big difference ,you need to work on 5litres (5000ml) at 100ml oil = 50-1 ok for the mont if semi syn or fuuly syn the rev 3 could use slightly less oil ie 90ml to 66ml = 55 to 1 or 75 to 1 i use 90ml to 5litres in my rev3 and 100ml in the mont google montesa cota 200 pics and you should find plenty Quote Link to comment Share on other sites More sharing options...

grahamjayzee Posted February 17, 2012 Report Share Posted February 17, 2012 I'm out next at the Brian Stonebridge (Cambridge Matchless) on 26th. I don't have much else planned. Guess I should take a look at the Gazette and start grovelling to the missus! Quote Link to comment Share on other sites More sharing options...
