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.

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL SAFETY COUNTERMEASURE (Recall 22V-061 / Service Bulletin MTB 17819). Extended 1st gear operation above 5,000 rpm causes exhaust radiant heat to melt the oil cooler outlet pipe. The heat guard installs directly between the #2/#3 header pipes and the oil lines.

INSPECTION TARGETRecall 21V-249 / KL9

Bore Counterbore Orientation (Mandatory Rule)

FACTORY WORKSHOP SPECIFICATION:

Recessed Bolt Head / Nut Clearance

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL INSPECTION (Recall 21V-249 / Bulletin KL9). Visually verify that the machined counterbores face OUTSIDE. The bolt head and nut MUST recess cleanly into the plate bores. If flat face is facing outside, plates were installed backwards at the factory and will bind and fracture.

FACTORY WORKSHOP SPECIFICATION:

Critical Recall Safety Countermeasure

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL COUNTERMEASURE (Recall 24V-113 / Bulletins KP9 & KQ0). Original low-density resin impellers absorbed solvent from automotive fuels, swelling and binding against the pump casing to cause sudden engine shutdown while riding. Replacement module features reinforced high-density resin impeller.
