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.

NHTSA #25V248000VEHICLE SPEED CONTROL:THROTTLE:THROTTLE POSITION SENSOR (TPS)

Received: 16/04/2025▼

Defect Description

Pure Sports Distributing Inc. (Yamaha of Hawaii) is recalling certain 2022 MT-09 Tracer GT, 2021-2025 MT-09 SP, 2021-2025 MT-09, 2022-2023 and 2025 MT-10 SP, 2022-2024 MT-10 and 2022-2024 XSR900 motorcycles. The brushes inside the Throttle Position Sensor (TPS) may slide excessively due to improper ECU programming, possibly causing unstable idling or an engine stall.

Safety Hazard / Consequence

Unstable idling or an engine stall can lead to loss of control of the motorcycle, increasing the risk of an injury or crash.

Factory Remedy & Repair Action

Dealers will reprogram the engine control unit (ECU) software and replace the TPS, free of charge. Owner notification letters were mailed on May 6, 2025. Owners may contact Yamaha of Hawaii customer service at 1-808-498-8248.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1- 888-275-9171), or go to www.nhtsa.gov.
