Chain tension puzzle

[buzzardbilly]

Well here's a question that I am sure some knowledgeable person will know the answer to  - do I measure the chain tension when the bike is cold or hot ?

Why do I ask ? Well, when I measure the tension after the bike has been on a run the chain tightens up by about 4 to 5mm (so my cold adjustment of 52mm as per the manual is then wrong) . Logically it should have expanded very marginally according to some comments I Googled on the topic

I understand the difference between the bike being on or off the stand (coincidentally this is also about 5 mm difference as well) but why should it be tighter after a run . I thought perhaps it might be do do with the suspension settling with someone on board but i am not exactly heavy and the bike is backed into the garage several metres so has time to resettle

Any thoughts ?

Some say "hot" some say "cold". I doubt it makes a big difference. Mostly I do mine cold.

I was surprised that Ducati think chain adjustment should be a dealer job and don't even provide the correct axle nut torque settings in the owners' manual

The fact they don't sell the workshop manual was also a surprise.  I've always liked to have one for every bike I've owned.
