April 30, 20206 yr 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.
April 30, 20206 yr 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.
April 30, 20206 yr Author I have changed the sprockets, it's just getting the chain length right then setting the tension.
April 30, 20206 yr 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.
April 30, 20206 yr Remember to size up the new chain with the wheel in the furthest forward position on the snail cam adjusters. Edited April 30, 20206 yr by cleanorbust
April 30, 20206 yr 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.
May 4, 20206 yr Author 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. Edited May 4, 20206 yr by netley spelling
