Twinshock

  1. Started by vintagecota,

    Does anyone have a Cota 25 tail light lense they can part with? It's small, about 1-1/4" round, dome shaped and screws onto the light base. It's the only thing I need for my 25 and so, of course, will pay WAY more than it's worth to get one.

    Just a reminder that the "Classic Off Road Show" is 10am this Saturday (12th March) at the Three Counties Showground at Malvern. If its anything like the show at Coventry last year there should be plenty of interesting twinshocks & pre 65's on display. Anyone else going? Martin

    Hi lads hope you will be able to help me out. I have a Montesa cota 200 and have a bit of a problem with the gearbox on it. When riding up hill it has a tendency to jump out of gear, has anyone had similar problems on this bike and if so what was it. I had an Ossa that had a similar fault and it was the spring for the detent plunger had snapped, is there a one of these fitted to this bike or is it a different system. Any help would be gratefully received. Cheers Glenn

And wanted to know what fuel i should use (i use Shell Optimax in my 315R), what ratio of fuel/oil mix and what oil to use in the engine ? Any tip's and advice (excluding "sell it !"), and help with spares would be much appreciated. Thanks in advance. Gaff.

    I was given a Montesa Cota 200 for my birthday about 6 years ago by my Uncle. The bike was in 'ok' condition but was abit hard for me to ride when i was only ten so it went back into the shed. It was there until summer this year when i decided to try and ride it - bad idea. It went very well for a while, but then the engine suddenly started rattling alot. The bike therefore pobably needs an engine rebuild to find the problem. Gearbox is fine and so is everything else exept wheel and swingarm bearings etc, t just needs tidying up. I got a new Beta at christmas and the bike is cluttering up the workshop so I want to get rid of it. Unforturnately this is all I know ab…

    Can anyone give me any suggestions what bike uses a simple 'bung' type petrol top of roughly 41mm diameter. The top I got with the bike is of a hard rubber/artificial rubber material with a plastic top, this has Chinese or Japanese style writing on it but no-one seems to know what it comes from. I am pretty sure its from an obscure bike oil tank or petrol tank. Unfortunately this is too worn to seal, hence the car cap I am using. Alternatively has anyone any suggestions what I could use - or modify to use as a top. I have just machined the original top for 2 O rings but am still not happy with the seal on this. I have been using one of those emergency car petrol ta…
