2012 owners -
I've just pulled the CCT from my 2012 with 44,000 miles on the clock.
I changed my CCT because the writing is on the wall for the 2012's & my bike was making a clearly audible slapping sound upon start up. About 30% of the time, the chain would slap three, sometimes four times before it settled down to its normal running idle. The Tenere's valve cover has a protective plastic guard on the inside of the cover, presumably, to keep a loose chain from wearing through the cast iron. My chain has been hitting that guard hard enough to put scratches in it. I bet if I had placed my hand on the top of the valve cover, when I punched the ignition button, I could have felt the chain hitting the underside of the cover...maybe not? Has anyone tried that?
Once removed from the engine, the old CCT fell apart in my hands. The cir-clips seem to be unable to hold the tensioner together.
I used the updated stock auto CCT. It took a bit of work to get the new tensioner spring to release.
If this unit starts making noise like the old one did, I'll replace it with a manual one at the next valve check.
Thanks to all for making this issue known.
