COULD BE YOUR VALVE SEALS OR PISTON RINGS DONT SOUND GOOD HOW MUCH MILES
I have a kx 250 dirt bike that keeps fouling plugs on start up. I rejetted it but that still didn't solve the problem. What could be the Problem?
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.
make sure it's getting fuel and make sure it's getting spark to the plugs.
your timing may be off or plugs are fouling

try replacing the spark plugs
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.

If you own a sled that has a two-stroke engine, your plugs may be fouling due to your oil to gas ratio mixture or your carburetor is running too rich and needs to be adjusted or rebuilt.
Oil and gas mixture too rich. : o )
A very good possibility is the opti spark distributor.If this distributor gets slightly damp,it can cause several problems.
