Teddydanson Posted 17 hours ago Report Share Posted 17 hours ago Hi all, just had a couple of hours on the old girl. Runs sweet as, but I noticed the chain was very slack after an hours ride, brought her back, undid the hub bolt, and it’s got to like cog adjusters on either side, I’ve turned them both the same and it’s tightened with a little slack, but not sure if the correct tension. I can get my thumb on the top of chain under inbetween the top guide, and thumb under the chain on the swing arm. I’ve tried to look but nothing video wise I can see to check. Thanks for any help.. kris Quote Link to comment Share on other sites More sharing options...
lemur Posted 17 hours ago Report Share Posted 17 hours ago (edited) If the chain tensioner is doing something when the bike is at rest with no rider aboard you are good to go, if the rubber block is touching the swingarm at rest that's not good. ... so far this year alone I spotted 3 bikes with the axle set crooked and I noticed it because the chain tensioner was doing nothing when they parked their bikes. Make sure the axle is good and tight and that your wheel bearings are perfect, wheel bearings wear out fast.

zippy Posted 1 hour ago Report Share Posted 1 hour ago What I typically aim for on chain tension on my 2015 GasGas: Bike on stand, wheel off ground. Able to place 1 finger between top of chain tensioner block and swingarm. From the back, look at tire and chain, give the tire a spin and make sure the chain runs straight and the rear sprocket is not crooked.
