Valve clearance report

For those interested in such things, I thought I'd post this. My first valve check at 13892 required no adjustments. My second at 29256 required one shim change. Here are the clearances. Please note that the first one was in inches, while the second was done in mm, so I had to convert the first set for comparison; hence there is some degree of rounding error.
HTML Code:
intake spec: .10-.20mm
exhaust spec: .20-.30 mm

         13892               29256            
front
  in-r      .15                    .12             
  in-l      .13                    .12
  ex-r     .23                    .25
  ex-l     .23                    .22

rear
  in-r      .13                    .12
  in-l      .13                    .12
  ex-r     .23                    .15->(installed: 1.70, needed: 1.60)
  ex-l     .20                    .20
I did not do the work myself, so I guess I can't gripe that they didn't go ahead and bump up the rear left exhaust to the middle of the range. On the other hand, it hasn't moved since last time, so no biggie.

I don't know what the shim sizes (1.70 and 1.60) represent, so now that I look at this, I realize that I don't know the new clearance of the rear right exhaust.

The right rear exhaust would now be 0.25mm if the measurements are correct. The front right exhaust clearance increased. That is not possible. I find the .15 move to .12 on the front right intake very unlikely and the .23 to .15 move is crazy. Between 17,000 miles and 48,000 miles om my bike, I had one exhaust valve close up 0.01mm. I question the competence of the people doing the work.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Seemed a little odd to me too, but I don't know enough to comment. Some of the differences are undoubtely due to rounding errors. Here are the raw inspection sheets. Note that the order is different, and "vertical" is rear:

Okay. I'll take a look.

Switching between metric and SAE gauges using go/no go tests could account for the apparent small differences but it doesn't explain the large change in the one valve that needed a new shim or the front right intake.

I'll ask the service manager about it.

I'm not sure I can see why only one seat would wear that much more than the others. It does seem to suggest a mistake either on the first go or the second.

How did you arrive at .25 for the rear right-exhaust? Do "1.60" and "1.70" represent total millimeters thickness of the shim?

No noticeable difference in runability or engine sounds, for whatever that's worth. Still runs great; always has.
