1. Warm up the engine for a few minutes, then turn it off.
Locate the oil drain plug on the bottom of the engine, just below the exhaust header. It is a 17mm hex bolt.
Position an oil drain pan under the plug.
Using a 17mm wrench, loosen the oil drain plug and allow the oil to drain into the pan.
4. After all of the oil has drained out, reinstall the oil drain plug and tighten it to 14 ft-lbs.
5. Add 3.2 Quarts of Honda GN4 Motor Oil or comparable SAE 10w-40 or SAE 10w-30 engine oil to the engine and check the oil level.
