Proper Method of Checking the Engine Oil Level

Because the upper (gearbox) oil reservoir is fed by the left oil pump, the oil level in both reservoirs changes under different operating conditions. Therefore, you must follow a specific procedure to properly determine the actual oil level in the upper (gearbox) reservoir.

Check the oil level when the engine is warm, after it has reached operating temperature. Let the bike idle for a minute or two on the kick stand, in an upright position. Then turn off the engine, and wait a minute or two for the oil to drain. Finally, balance the bike in a vertical position, and observe the engine oil level in the viewport. If the engine has the right amount of oil, the level will be between the upper and lower scribe lines, as shown in the photo below.



If you fill the RX3 with the specified, 1.7 quarts of motor oil at each oil change, you will have the proper amount of oil in the crankcase. You can verify the engine is not burning oil, or leaking oil, by checking the oil level in the manner described above.
