dibdab Posted August 3, 2007 Report Share Posted August 3, 2007 (edited) I know this is probably a silly question... Since riding a trials bike I have never been really sure where a chain should be adjusted. I know how to adjust but not to what tension. Can any of you far more experienced riders give me some pointers please. Thank you. Edited August 3, 2007 by dibdab Quote Link to comment Share on other sites More sharing options...
sr34 Posted August 3, 2007 Report Share Posted August 3, 2007 the chain as you know runs through a rubber tensioner i usually adjust the chain so there is approx 20mm gap between the top of this tensioner and the underneath of the swinging arm its what my manuals advise Quote Link to comment Share on other sites More sharing options...

scorpa3 Posted August 3, 2007 Report Share Posted August 3, 2007 It's always worth sitting on the bike with all your weight after you've adjusted the chain, and see if it's gone tight.... ie like a guitar string. If it's too tight, this can be worse than slightly too slack. Quote Link to comment Share on other sites More sharing options...

Cheers if you have a maintenance stand then i would advise using that :-) Quote Link to comment Share on other sites More sharing options...

copemech Posted August 4, 2007 Report Share Posted August 4, 2007 running your finger between the tensioner block and the swingarm is a good guage and rule of thumb! Not too much, not too little! Quote Link to comment Share on other sites More sharing options...

Not too much, not too little! Thanks for the advice everyone: Just to be sure then I adjust the chain so that when I have my full weight on it there is about 20mm between tensioner and underside of swingarm?

Right, I think I have it now, just adjusted it and have the 'thumb gap' whether it's on or off the stand. It does seem quite tight, but that is probably because I had it way to loose before. Thanks again. Quote Link to comment Share on other sites More sharing options...
