Post Script

Earlier this month, I picked up a 2011 R1200GS on the East Coast. It had 1,400 miles on it. Barely touched. I rode it 2,700 miles, from Florida to California. The bike required a half-quart of oil during the transit.

Arriving in California, I note the telltale signs of a rear main seal leak: oil seeping from the mating surfaces between engine and transmission, and pooling on the skid plate. The bike has 4,150 total miles on it.

Come on BMW.

If I were trying to blow out seals, how would you recommend I do it? This is at least my third episode blowing out this particular seal in an R1200GS. I must have the magic touch! (My 2005 R1200GS rear main seal failed in the first 6,000 miles, ruining the clutch.)

[January 14, 2014 update:]

At 4,263 miles the following work was done by Santa Rosa BMW, Windsor, CA:
