netley Posted April 30, 2020 Report Share Posted April 30, 2020 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. Quote Link to comment Share on other sites More sharing options...
lineaway Posted April 30, 2020 Report Share Posted April 30, 2020 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. Quote Link to comment Share on other sites More sharing options...
netley Posted April 30, 2020 Author Report Share Posted April 30, 2020 I have changed the sprockets, it's just getting the chain length right then setting the tension. Quote Link to comment Share on other sites More sharing options...
lineaway Posted April 30, 2020 Report Share Posted April 30, 2020 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. 1 Quote Link to comment Share on other sites More sharing options...
cleanorbust Posted April 30, 2020 Report Share Posted April 30, 2020 (edited) Remember to size up the new chain with the wheel in the furthest forward position on the snail cam adjusters. Edited April 30, 2020 by cleanorbust 1 Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted April 30, 2020 Report Share Posted April 30, 2020 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. 1 Quote Link to comment Share on other sites More sharing options...
netley Posted May 4, 2020 Author Report Share Posted May 4, 2020 (edited) 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, 2020 by netley spelling Quote Link to comment Share on other sites More sharing options...
