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 M12 x 1.25 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.

NHTSA #21V361000EXTERIOR LIGHTING:TURN SIGNAL

Received: 01/01/2021▼

Defect Description

Ducati North America (Ducati) is recalling certain 2021 Scrambler 800 Night Shift motorcycles. The front and rear turn signal lights may not flash brightly enough. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety Hazard / Consequence

Turn signal lights that aren't bright enough can reduce other driver's ability to see that the turn signals have been activated, increasing the risk of a crash.

Factory Remedy & Repair Action

Dealers will replace the front and rear turn signals, free of charge. Owner notification letters were mailed on June 28, 2021. Owners may contact Ducati customer service at 1-888-391-5446. Ducati's number for this recall is SRV-RCL-21-009.

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.
