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:

Rear main seal and counterbalance seals leaking (Warranty)

2011 BMW R1200GS

Tallahassee, Florida

Take ownership of 2011 BMW R1200GS

With only 1,409 miles on the bike (original purchase September 27, 2011), my brother and I trailered it from Waterbury, VT to Tallahassee.

Over the next six days, I rode 2,700 miles to Santa Rosa, CA.

En route, added 1/2 quart of 20W50 oil (to bring from bottom to top of oil sight glass.)

Upon arrival in California, with 4,100 miles on the odometer, I noticed oil leakage along engine-transmission housing interfaces. Oil has also collected in skid plate. I suspect a rear main seal leak.
