    What does it mean when gas leaks through your spark plug porcelin around the insulator and not around the hole in head ? Still ran for awhile then stopped running all the sudden while i was ridding and never started again

    What do you mean? Gas is coming from around the top of the plug where the boot connects, or where the plug screws into the head?

    If it's coming from where the plug screws in at the head: Does your plug have the washer?
    If it's coming from the top of the plug near the boot: Did your piston slap the bottom of your plug so hard that it pushed it out of the porcelain?

    Dumb question on my part, but is the plug tight?

    Are the threads on the head stripped?

    Is the plug cross-threaded?

    the plug is tight and does have a washer and is leaking not around the hole of the head but where the porcelain is around the center of plug on the outside . if my cylinder slapped my spark plug im unaware of it

    You'd be aware if your piston was hitting your spark plug.

    Nothing should leak from anywhere.
