Official Workshop Manual Compression Test Protocol

Step 0 of 5 Completed

Step 1: Engine Operating Temperature

Run engine until coolant reaches 60°C - 80°C (140°F - 176°F). Cylinder expansion brings rings and pistons to true operating clearances.

Step 2: Spark Plug Removal & Port Clean

Blow compressed air around spark plug wells to eject grit, then remove all spark plugs. Thread in M10 x 1.0 whip adapter hand-tight with fresh O-ring.

Step 3: Wide-Open Throttle (WOT) Lock

Hold throttle grip fully wide open (or lock throttle bodies open) to eliminate intake butterfly vacuum restriction and ensure 100% volumetric cylinder filling.

Step 4: Battery Tender Voltage Stabilization

Connect a 12V shop battery tender or booster. Starter must sustain uninterrupted cranking speed (350 RPM) to build maximum dynamic stroke pressure.

Step 5: Crank 4-6 Compression Strokes

Engage starter until gauge needle ceases rising (typically 4 to 6 strokes). Record maximum peak pressure and compare against the OEM limits above.

Defect Description

BMW of North America, LLC (BMW) is recalling certain model year 2013 R 1200 GS motorcycles manufactured November 2012 through August 2013. Pressure inside the transmission may cause the transmission output seal to be pushed out of place.

Safety Hazard / Consequence

If the output seal ring is pushed out of its proper position, oil may leak from the transmission onto the rear tire, increasing the risk of a crash.

Factory Remedy & Repair Action

BMW will notify owners, and dealers will fit a bracket to prevent the transmission seal from being pushed out of position, free of charge. The recall began on June 17, 2014. Owners may contact BMW customer service at 1-800-525-7417.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
