Hey all, I’ve read every damn chain adjustment post on every scrambler forum and still can’t seem to figure this thing out. I’ve been riding and working on bikes for a long while and have adjusted enough chains and never had a problem. But Ducati’s instructions on where and how to measure are tripping me up.
When I adjust the chain to spec (27-29mm) it feels way tight. And I can hear it and feel it when I ride. That worried me so I loosened it up again and worry it’s too loose. It’s driving me mad.

So my procedure is :
-find the tightest spot,
-set the bike on the side stand
-place a ruler on the ground, about lined up with the high curve of the swing arm,
-press down on the chain (towards the ground) let go, take note of the measurement
-Push the chain up and note the measurement
- subtract the two and get the difference. This number should be between 27-29 mm

what the heck am I doing wrong!
Somebody save me 😖
Photos of your measurements would be super helpful.
Thank you 🙏

When I had a monster the manual called for measuring the distance from the swing arm and not the ground. Don’t know if it’s the same for scrambler.

Hey Desmoduc, tried that too but to get the 27- 29mm that way, the chain is way way too loose. Like coming off the sprockets loose.
And I am measuring from the center of the pins on the links, up to the swing arm, at equal distance between the sprockets.
