Anyone up on the max time you can go on an F800 GS valve adjustment. My bike has 16,000 miles on it and according to BMW of Denver I am scheduled to have the valve adjustment check up at 18,000 miles (used to be 12,000) The bike is a 2009 and has had religious oil changes and not a terrible amount of riding through dust. My problem is that I am about to head off to ride around Mexico... probably put on around another 4000-4500 miles and would be at 21,000 miles potentially before I got back and would have the valves checked for adjustment. Any input on that being stupid rather than having the valve adjustment early? Bike is running like a clock right now. Just got back from a full trip Colorado/Alaska/Dawson Yukon. Not a single problem on the trip.
