2004 Yamaha PW... | Answered on Feb 01, 2018


Hi, Anonymous if you are experiencing excessive oil coming out of the crankcase breather or air filter please drain all engine oil and replace half of the same oil that comes out. Many riders are overfilling their oil system because they do not know how to properly read their oil site glass or dipstick. The following procedure works on nearly all 4 stroke engines but to be on the safe side you should refer to your owners manual. Use your center stand if you have one.
1. Bring the engine up to operating temperature or let idle for 5 minutes.
2. Turn off your engine and let it sit for 2 minutes, this will allow the oil from the top end to drain to the bottom.
3. Hold your bike straight up or on the center stand and wait 2 minutes for the oil in the bottom of the engine to be level in the sight glass or on the dipstick.
4. Your oil level should be between the top full mark and the bottom add oil mark.
5. Never overfill your oil system it will cause problems:
a. oil leaking out of exhaust pipes.
b. oil leaking out of breather pipe/hose.
c. oil carryover into the air cleaner.
6. Your oil site glass must "NEVER" be completely full or empty drain or add oil as necessary.
7. Your oil dipstick must "NEVER" be over the full mark and should never be below the add mark drain or add oil as needed.
