Note: secondary spark plugs for both right and left cylinders were fouled. The left secondary was heavily-fouled with carbon and debris. Spark plugs were perhaps not properly torqued last service as some were too easily loosened and showed signs of oil and/or gas seepage on threads. Primary plugs were clean, but worn.


Transmission output shaft seal leaking


Will replace when I can afford it.

Other work to be performed by dealer: bleed brake hydraulic system, synchronize throttle bodies, check suspension and computer codes.

Front suspension dampening failing


Suspension sounds like it is bottoming out under moderate shocks (such as a small pothole at very low speed.) Can't tell if it's the front spring strut or front forks (or both.) The front spring strut was replaced at 80,785 miles, so I would be surprised if it has already failed.

(Apparently, the only way to check fork fluid levels is to remove the forks.)

BMW R1200 GS Problems, Safety Recalls and Defects


Campsite on Montana rangelands near Lake Elwell


For those searching for an "official" summary of issues related to the R1200GS, the Automotix database collects information from both the National Highway Traffic Safety Administration (NHTSA) and from BMW and publishes it in one convenient location.

Of course, this doesn't capture issues that, although reported by many owners, do not meet the criteria for a NHTSA or BMW recall.

(I've personally experienced three of the failures cited in the recall notices: fuel pump electronics seal failure, making bike non-operational, loose clutch components leading to clutch failure, and the failed speedometer pick-up seal leading to oil on rear brake components.)

Santa Rosa, CA

Punctured rear tire


Picked up a staple in the rear Metzeler Tourance tire. [9/21/11 Update: removed tire from rim and found three more pieces of staple in the tire. Not repairable.]

Over the past few months, I patched the Michelin Anakee 150/70VR17 that had picked up a nail last November. Today, I remounted this tire (on the spoked rim), and will eventually patch the Metzeler as an emergency back-up tire.

Mounting and balancing: $40.00
1 ea. Napa Plug Patch Repair Kit, Balkamp #710-645 $11.50

Total: $51.50


Miles on the Anakee: 2,496
Miles on the old Tourance: 10,896

Note: the decision to patch this tire was taken only because my current use of the motorcycle is limited to daily trips around town, with a maximum speed under 70 mph, carrying no gear, passengers, etc. If/when riding circumstances change, the tire will be replaced.
