Check that the sparkplugs are the right one listed for the bike. If that is not the problem, check your fuel mixture, it may be too lean causing the engine to run hotter than it should. If that's ok then check your ign timing.


Could be running your gas oil mixture too heavy


the plug wet? you could be flooding too, clean needle valve and seat.

Have you noticed any power loss. Rings maybe starting to fail

The problem could be many things. With the check engine light coming on, it could be an internal issue in the engine, or broken engine mounts causing the vibrations.

this could be a number of reasons it could be your mixture screw or it could be running lean or rich the best thing to is a plug chop see what colour it is if its black and oily its running rich if its white its runing lean also if its running lean your engine will sound flat and could course it to seize or the main jet could be to big or to small its always best to over jet a a 2stroke and work down till you feel the engine getting better hence the bog going away hope this helps

funny this should pop up i just read about this, it will run with the buhw but they don't fire as hot as the buhw-2 due to a shorter distance for spark to jump, this could lead to premature fouling. if your engine calls for the buhw-2, i would stick with them

Will your car run with a blown head gasket?

Almost any engine will run with a blown head gasket. Having said that: NO engine was ever meant to run with a blown head gasket!!!! Several things could be happening simultaneously while the engine is running: coolant could be entering the oil pan, causing a loss of friction protection, destroying the bearing surfaces of the major rotating members; oil could be entering the cooling system, seriously diluting the coolant, reducing it's ability to remove heat from the engine; third, oil and/or coolant could be entering the combustion chambers, fouling the spark plugs (inhibiting ignition spark), and forming unwanted unburned deposits on the pistons, cylinder walls, and compression rings, causing accelerated wear to all moving parts. DO NOT OPERATE AN ENGINE believed to have a blown head gasket---it will destroy the engine.

What will cause a 89 Camaro rs to keep getting oil on the plugs and fouling them out?


I have a 77 280z with fuel injection and im getting gas in the oil whats causing it?

Look to see if your plugs are fouling. If they are fouling in specific cylinders, the cylinders may be flooding. If it floods enough, it'll either go out your exhaust, or into your crankcase. Could be a stuck open injector, broken fpr....definitely a fuel system management issue.

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.
