Valve adjustment (self-service)

For the first time, I used the feeler gauges purchased in 2005 from BMW of San Francisco for the R1200GS. (All previous valve adjustments were done by dealerships.)

I noticed the gauges provided were 0.10 mm (intake) and 0.20 mm (exhaust). Followed the excellent procedure write-up on the R1200GS.info website. However, that site shows the clearances as 0.15 and 0.30 respectively.

I then consulted the BMW R1200GS service manual CD and it too shows 0.15 and 0.30. I set the valve clearances with the gauges I have, but will have to figure out why I was sold 0.10 and 0.20 gauges.

Found one of the left valve cover screw sockets stripped out. Since this is the first time I've personally removed the cover, I must assume a technician had over-torqued the screw.
