  • spark plug color

    well mine is brown, on the denso site it says it should be light tan, does it matter that im using a 2-stroke engine?

    it mentions 2-stroke in the oil fouling category

    i dont really understand your question but if your plug is like a dark brown that means your not burning the oil and you can fix that by going to a higher gas mix say if your using 25:1 and your plug is a dark color then you should try to run it richer with like 32:1 or 40:1 mix but thats only after the bike is broken in

      after you ride put your finger in the pipe and see if there is alot of oil....and if there is then definitly run the bike richer with a higher rayio as like i said in the other post like 32:1 or 40:1
