Spark Plug Fouling

Spark Plug Fouling
My son has a 2004 Predator 50. The spark plug keeps fouling. I have tried another one but that has fouled also. We have just finished break in running the extra oil and I am now running 93 octane. Do you have any ideas or suggestions of what could be causing this? Any advice would be helpful

too much oil as you indicated or runnning with the Choke on for an extended period. Try the correct fuel to oil mixture. If the mixture is correct start the Quad returning the choke to the the off position and running it at full throttle or high rpm to clean out the combustion chamber or heating the engine to a point where it will burn off the extra oil adhering to the plug. However, as I said earlier, it is most likely you have an incorrect mixture or the choke is not shut off.
