If the oil mix is too high well--really, it's the air/fuel mix. It is too rich (not enough air). Some things to try: clean air filter, make sure the little orifices in the carb are clean, check the float level, air (or fuel) screw adjustment, wrong plug, one or more jets too rich. You will need to do some research on this one if you want to permanently fix it. But if you work through it, you can make it stop fouling plugs. When I first got my cr125, I fouled plugs after every 20 minutes of riding. After working through the possibilities, I found that the float level was wrong and the main jet was wrong. Now its been 2 years on the same plug.

What spark plug should you use in your 2003 yz 125?
Try www.bikebandit.com, they have a large selection of oem and aftermarket spark plugs, if you keep fouling plugs try to rejet the carb, or swith to a hotter spark plug.
What is a fouled spark plug?
Fouling spark plugs can happen when the tip temperature is insufficient to burn off carbon, fuel, oil or other deposits and causes spark to leach to metal shell...no spark across plug gap will cause a misfire. Wet-fouled spark plugs must be changed as they won't fire. Dry-fouled spark plugs can sometimes be successfully cleaned by bringing the engine up to the operating temp.
Why is a 2007 Kawasaki ATVs' spark plugs fouling up?
Oil and gas mixture too rich. : o )
What would cause a 1999 Chrysler cirrus to stall at different speeds?
check your spark plugs they could fouling up or gummed up enough to spark for a while then as they heat up become worse. a lot of common problems with engine stalling can be directly related to plugs or coil etc.
Why does your john deere gator keep fouling spark plugs?
Because there is a design flaw in the Kawasaki water cooled engine.
What is the cause of shaking due to acceleration?
Bad spark plugs, spark plugs wires, etc.
Why is your spark plugs always fouling out in a 2002 intrigue?
There's something getting in the cylinder that's not supposed to be there. Are all plugs fouling similarly? Likely an improper fuel mix (broken MAP sensor, O2 sensor, etc), or a leak in the intake system. Is it just one or two? Probably a cracked head gasket or worn piston rings on those cylinders. There's lots of photo tips on spark plug fouling on the web - the various colors and residues lead to clues as to what's causing it. Need to fix the cause, just changing the plugs won't work.
What would cause carbon foul on spark plugs on a 1967 Chevy truck?
Carbon Fouling of Spark PlugsUsually spark plug carbon fouling is caused by either the fuel mixture [ratio of fuel to air] is too rich [too much fuel], OR it could be that crankcase oil is getting into the combustion chambers [cylinders].Crankcase oil fouling is most often caused by either worn or broken "oil" rings on the piston, or on overhead valve engines, worn out valve-stem guides.
How do you keep your spark plugs from fouling up?
Correct tuning, correct heat range plug, correct oil/gas ratio for the motor
Why does my Riding mower have oil on the spark plug It will not start.?
Valve guides are worn and piston rings are worn crank case oil seeping up to spark plug fouling them change spark plugs or try irridum plugs they sometimes work in engines that consume oil.
Can a bad exhaust cause black stuff on the spark plugs?
It's usually fouling due to air/fuel ratio too rich or improper heat range or faulty ignition coil as most common causes.
Will a bad alternator cause new spark plugs to smoke?
Spark plugs don't smoke. A bad alternator would cause a dead battery.
