2010 Ultra Limited Drive Belt constantly Loose
I just did my 20,000 mile service. I am getting ready to ride it to Daytona for bike week, about 520 miles from N. Ga. After getting bike up on lift I was surprised to see the drive belt sagging. The last time it was adjusted was at the dealing after they put on a new rear tire, about 3K miles ago. I remember the last service I did, it was loose then too, but not as bad. So, anyway, I tighten it as the manual suggests, vertical, cold, in neutral with back wheel off the ground using the 10lb tool. Noticed that I am getting close to running out of cam on the axle adjusters. Took it for a 6 mile test ride, got back and it is loose already, not sagging like before, but using the 10lb tool, I must have 3/4 to 7/8 inch of travel.......?????? WTF is going on?

20,000 miles is nothing for those belts.
Are you sure the cam adjusters are positioned the same?
Torquing the axle nut to 90/100 ft/lbs?
Checking the tension with the tool in several locations on the belt?
Little tip I learned here, use Never Seize on the back of the axle bolt so when tightening, the cams do not move once their where you want them.....

Sounds like the belt may be bad and stretching. If the axle nut is still tight and the axle is not moving it has to be the belt. I would tighten the belt mark the axle location and go for a ride. Then come home and check it. If the axle is in the same spot and the belt is loose, replace the belt as its bad and will probably leave you stranded is the future.

oh i certainly know that and IIRC the moco recommends a change at 75,000 miles but nonetheless it wouldn't be the first one I see stretched well below it's recommended interval of change.

I too had similar issues after the dealer replaced the rear tire. I took it back the next day and the same thing. The belt deflection was too loose. I then referenced Service Bulletin M-1284 dated August 9, 2010 for 2009 and later Touring models noting that the deflection criteria has been changed. It went from 3/8 - 7/16 to 3/8 - 9/16. I used two wrenches (Axle Nut Torque Adapter HD-47925 and Jims Tool 3rd hand axle locker #970). I set the torque on the high side at 100 lb-ft. I applied some yellow torque stripe paint to ensure that there was no movement of the axle nut or weld nut. I cross referenced both axle cams to verify that both were even with equal amounts of displacement. Yes, with the correct range adjusted the cams appear to be nearly at their limits. However, the tension under like measurement conditions repeatedly remained the same and in spec. I cannot and do not trust the dealer and their abilities. They have on many occasions made mistakes that are inexcusable. Nuff said.
