Well, considering that I've had more wrenching than riding for over a year, the bike has only 14K on it....
Hoping to do much more riding this year, but I wasn't aware of this tensioner issue and it's been 3 years since I was in there.
Today, I pulled everything out of the clutch side... 

And here is a front view of the tensioner.  The hole isn't worn out like in the German photo. 

And there isn't any wear on the tensioner parts either. 

Actually I am photographing the whole process, and I'll post a topic in the tech section when I get it all sorted out.
