NOTE: Avoid overtightening the three cap bolts.

Step 9. Refill the engine with 2 quarts of 10W-40 motorcycle oil. Make sure the oil is designed for wet-clutch motorcycles.

Step 10. Reinstall the oil filler cap/dipstick, then start the engine and let it idle for a few minutes to pull the oil through the frame and into the crankcase. 

Step 11. Shut off the engine and let it sit for a couple of minutes so the oil can settle.

Step 12. Remove the oil filler cap/dipstick and check the oil level. To check the level, hold the filler cap/dipstick against the threads but don’t screw it in. Top off the oil if necessary, then reinstall the oil filler cap/dipstick and you’re done.
