Motion Pro 2-Stroke Timing Kit (08-0250)
Updated June 12, 2026
The Motion Pro Timing Kit (part number 08-0250) is a specialized diagnostic tool designed for setting ignition timing on two-stroke water-cooled engines. It allows technicians to accurately measure piston position relative to crankshaft rotation, enabling precise adjustment of spark timing for optimal engine performance.

How It Works
The kit includes a 1.5-inch dial indicator (scaled in millimeters), extension rods, and a 14mm spark plug thread adapter. The adapter screws into the spark plug hole, and the dial indicator is inserted to measure piston travel. By rotating the engine and noting the indicator readings, the user can find top dead center (TDC) and determine ignition timing in millimeters before TDC. The tool is designed to clear frame tubes on most modern water-cooled models.
Vehicle Fitment and Usage Notes
This kit is intended for 2-stroke water-cooled engines commonly found in motorcycles, ATVs, and other powersports vehicles. It is not directly compatible with air-cooled engines; a separate adapter kit (Motion Pro 08-0249) is required for those applications. Additionally, due to limited clearance between the cylinder head and frame, the kit cannot be used on Yamaha RD two-stroke twins with the engine installed in the frame—engine removal is necessary for those models.
Common Failure Symptoms Addressed
Incorrect ignition timing in a 2-stroke engine can cause symptoms such as hard starting, poor idle, loss of power, excessive vibration, overheating, or pre-ignition (pinging). Using this timing kit allows the mechanic to verify and adjust timing to manufacturer specifications, resolving these issues and preventing engine damage.
