Timing Protractor Set Maintenance Parts

A timing protractor is an indispensable maintenance tool for high-performance tuned engines.
It is used to read, inspect, and adjust the opening/closing timings of each port in 2-stroke engines and the valve opening/closing timings in 4-stroke engines, based on the crankshaft angle.
Furthermore, the protractor is made of etched stainless steel for durability.
This ensures that you can always use it in a clear and legible condition.
