All these models draw their oil from a common location within the crankcase, situated near the drain bolt and oil screen.

Testing Oil Pump Functionality

To verify the operation of the oil pump without the engine running and with the spark plug removed, follow these steps:

1. Loosen the head nut that is equipped with a copper washer.
2. Kick the bike over repeatedly until oil begins to seep from the area around the washer.
