The bike is a 2007 R1200GS with about 26,000kms (16,000 mi). Had it serviced today. Mechanic noted that the rear drive oil was like "raspberry jam" as if it contained water. Said he'd never seen it like that. Noted that the bearing felt rough, but wasn't recommending replacement of the drive. I bought the bike last fall and have put about 4000 kms (2500 miles) on it. Anyone had a similar experience? I haven't seen any sign of oil around the boots or other signs of leakage. I've never driven it through the water, but I can't say anything about the previous owner's habits. What about salt water? No sign of pitting or rust that would suggest its been left under water!
