Where does oil fouling on a spark plug come from?
The oil can come from the piston rings, valve stem seals or the positive crankcase ventilation (PCV) system. Leaking piston rings can be diagnosed with a leak-down test. If one cylinder has oil fouling, a relative compression check can help to assess mechanical issues with that cylinder.
What happens when a spark plug gets fouled?
Beyond the oil getting past the rings, the oil trapped in the rings can become carbonized and cause damage to the cylinder walls. This can lead to even more damage and more oil consumption. In some cases, the oil consumption results in a low-oil condition that would cause damage to the bearing surfaces.
What causes oil fouling in a car engine?
Malfunctioning PCV systems are becoming a leading cause of oil fouling in modern engines. These systems have become more than just a spring-loaded check valve. Modern systems can separate oil from the crankcase vapors and electronically regulate when the engine ingests the vapors.
Why does my dirt bike keep fouling spark plugs?
Incorrect jetting is one of the most common causes of plug fouling, but we’ll look at what the top reasons why your dirt bike keeps fouling spark plugs and how you can fix it before spending a ton of cash on continually replacing spark plugs.
What should I do if my spark plug is fouled?
First thing to do if your spark plug has been fouled is to check the air filter. If it’s really dirty, that makes it difficult for air to get through to the engine, causing a rich condition. Either clean it thoroughly with some Air Filter Cleaner (Amazon), or buy a new filter.
How does oil build up on spark plug?
As the oil deposit builds up around the electrode, the electrode will eventually fire toward the oil deposit rather than on the curved round tip on the end of the plug.
The oil can come from the piston rings, valve stem seals or the positive crankcase ventilation (PCV) system. Leaking piston rings can be diagnosed with a leak-down test. If one cylinder has oil fouling, a relative compression check can help to assess mechanical issues with that cylinder.
What does a fouled spark plug look like?
A fouled spark plug occurs when the plug isn’t burning fuel normally, leaving damage to the plug which can cause the engine not to start. A normal spark plug will appear dry with a grayish color. A wet spark plug can indicate water in the fuel while a white residue on the plug can point to a plug that is too hot.

What kind of wiring does a Mk2 starter use?
From here i went on to remove the wiring from the brown coloured connector (T6) to the starter. This is a medium sized red wire which is covered along its whole length in black heatshrink. The plug on the end is a single pin packard connector and the other end terminates at the brown plug.
What is the spark plug gap for a 1977 Kawasaki Kz1000?
Besides the KZ1000 Kevin also owns a 1975 Kawasaki H2 and a Yamaha RD350LC. tiki4tara-blog asked: What is the spark plug gap for a 1977 Kawasaki KZ1000 LTD?? Thanks .028 to .032 inches. Do you notice how hard it can be to get an older motorcycle to idle smoothly, especially when the engine is cold?
What happens if the ignition is wrong on a Kawasaki Kz1000?
Ignition timing is important. If the timing is wrong it will affect performance. Here’s how to time your KZ1000 with a timing light. Another ignition problem affecting the idle is the ignition advancer. The advancer has two springs and they lose their tension with age and mileage.
Where is the compression gauge on a Kawasaki Kz1000?
Compression check. Buy or borrow a compression gauge with a 14mm adapter that will screw into the KZ1000′s spark plug hole. Before taking measurements, warm up the motor. Taking the bike for a ride will warm it properly. Unscrew all the spark plugs, put the caps back on each plug then install the compression gauge on cylinder #1.
