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

Yes, there is a detent plunger on the top of the left case half. It looks like about a 19mm bolt head with a large erect nipple.

Now you know why I like Montesas so much.

Thanks mate i'll start my investigation there. And your secrets safe with me.
