    15F spark plug problem

    Buddy has a 15f and went to do a "tuneup" and broke the plug at the thread. What is the easiest way to extract the plug. I suggested taking the top cover off but haven't worked on a 4 stroke kawa before. Suggestion needed and wanted.

    thanks for any help you guys can give.

    This is the second time I have heard about this. You could try working it out with a EZ-out, but be careful not to mess up the head. The best way would be to pull the head. Big bucks unless you can do it yourself.

    Were you by chance trying to remove them with the engine warm or hot?

    We have done this 3 times !
    On the first machines the engine was warm, next engine cold, third engine cold... Always the spark plug towards the front !
    We never change spark plugs on a 15F if it`s close to a race.

    Now we put some kind grease on that is OK with hot temperatures as well, no problems after that. You need to take the head off, leave it to someone who knows what they are doing are my suggestion.

    u should put a dab, and i mean just a little bit, of anti sieze on the threads. also make sure you dont overtighten them. some people think spark plugs are like lug nuts for wheels. dont use the gorilla strength please

    There is a torque spec- 113in-lbs( Note:inches not foot-lbs) and I use it. A little anti-seize and torque.

    i would start by pulling the head and use a smaller size drill bit for this. carefully drill away, at this point i dont think u are going to be able to unsscrew it.

    update on spark plug removal

    thanks for the replies

    got the plug out. It was the front cylinder. Took the pipe out and then the head. Tapped into the plug itself and screwed it out. Had to put another insert in there for a new plug as we stripped the original threads. But will definately use a dap of antiseize and grease around the plug to keep water/moisture in seeping in too much.

    Now we ran into a problem with the ski running like crap. Unfortunately it was stored with no stabil or fogging oil. ski cranks up and max rpms when there is no load but as soon as you put a load on it 5800rpms. Can't figure it out of why 5800rpms. Drain the gas, injectors are clean, going to put another fuel filter and hopefully the ski runs like a champ.

    anybody have any suggestions of what it can be or what else to do.

    thanks
