The BGM PRO timing disc is an indispensable tool for accurately measuring valve timing and adjusting the ignition on 2-stroke engines.
When tuning cylinders, changes to the ports directly affect the timing and, consequently, the engine’s character. A degree disc allows you to measure and verify these values with precision.
Suitable for engine blocks with a 10 mm or 12 mm crankshaft thread, including Piaggio, Vespa, Lambretta, and other 2-stroke engines.
