Hey there, tore my M1100S down for the 30,000 (31,575 actual miles) mile maintenance and found the Verticle Cylinder has a bad belt tensioner roller. Not sure how common this is but thought I'd post up my findings. I think I'll repace both of these Fixed Tensioner Assemblies and both of the Complete Cylinder Tensioner Rollers unless folks can vouch this failure is not common and I dont need to replace all of them.

Anyone find these for better prices than Omaha Ducati? $55.07 each and $72.62 each. I'd happily by from a sponsor ;-)

I've seen it once on those style of roller, an S2R1000 that lived outside and relatively close to the beach.
Bike had 29k miles on it.

One roller had no balls left in it.

Other three would make noise when spun, and would spin freely, so the seals were obviously sacked.

thanks for the Reply SpeedDog, maybe I'll give them a good spin and check they still have tension and replace the one and call it good then.

If i had that many miles on mine and the bearings looked that way i would change all of them.  Talk to a local bearing supply house and see if they can cross it to a good brand of bearing.  Maybe one of the others that looks better has a number on it.

I had the bearings on the adjustable tensioner on my 620 give out. Kind of a pain to pull off and replace, but as far as I remember, they're the same bearing as what's in the clutch pressure plate. Two of them are pressed on back to back to make the full width of the belt. Got mine form ca-cycleworks. If i were in my garage right now I'd read the part # off of the spares. Pretty common size. Definitely cheaper than what you quoted in the first post.

Just a quick update, once I got the belts off I found that 2 of the other 3 were not in great shape so I went ahead and ordered all 4.

In addition For the 2ND time now (out of 4 total checks) on the Vertical Cylinder the Exhaust side both the Opener and Closer are out of "Checking" Spec. I have a "Sinking" feeling I may have a valve that is pulling into the head...

On my S2R1K once I set the valves on the first check I never had to mess with shims again, it always had stayed within Spec. Although at this point I do have about 7500 more miles on my M1100s than I had on my S2R1K.
