Should the Kawasaki 400 use 92 or 95 octane fuel?

[GiaRose]

Kawasaki 400 can use both 92 and 95 octane fuel. Different grades of gasoline have different octane ratings. The higher the octane rating, the better the stability of the gasoline. Using gasoline with too low an octane rating can cause engine knocking, which is an abnormal combustion state in the engine. Knocking occurs when the engine is in the compression stroke, with both intake and exhaust valves essentially closed, and the piston moves upward to compress the combustible mixture. As the combustible mixture is compressed by the piston, both its temperature and pressure will rise.
