Chain replacement

Recommended Posts

Hi, I'm replacing my chain and sprockets on my 1981 Montesa 349. I've never done this on a bike with a tensioner. Any hints and tips out there?

Cheers.

 The tensioner won`t be the problem. The counter shaft can be a hard one. My old 348 took a lot of heat before it popped off.

I have changed the sprockets, it's just getting the chain length right then setting the tension.

 Well, it`s better to cut it too long and cut again. When a chain is cut it is actually a link and a half.

Remember to size up the new chain with the wheel in the furthest forward position on the snail cam adjusters.

It is possible that the old one had been shortened during its life so it's not foolproof to uses the same number of links.  Best to do as Cleanorbust suggests.

Hi, Thanks for all your input and apologies for late response.

I shall be trying to fir the chain later this week. I won't be using the old chain as a guide as I am changing the gearing.
