Not to jack, but I just replaced a flat tire and was tested on adjusting the chain back. It is self explanatory in the manual, but it did not work the first time. I got some popping and what looked like a little sprocket wobble. I had it up on my new Pit Bull.
So I loosened it all back up and started at the longest mark on the arm. I then put it on the side stand as instructed in the manual. Then I adjusted each side one mark at a time until it was good. Since it was no longer on the stand I could not just start and put it in gear...so I got on it and rode it around the block. I did not notice any popping or wobbling?? Maybe doing it on the side stand is the better??
