    Angry Broken Plug....ARRRGH!

    Torqued my #1 Cylinder plug down to 7ftLBs and the damn threaded sleeve breaks in the FXHO head!



    Planning on using a masonry nail tomorrow to wedge into the gap and then turn it out using a socket wrench and just the extension. Really pissed tonight guys, anyone had this happen on one of the FXHOs and any recommendations apart from my caveman method to extract the threaded sleeve, all would be appreciated.

    I had the same problem last year with my FXHO. The torque rating is too high, they have lowered it since. I put them in now with a short ratchet, I no longer torque them. Tighten them until you feel the washer crush and then give it a little more and you are done, plus always use antiseize. To get the broken plug out my friend a Yamaha tech used a paddle wood drill bit and machined it to fit inside of the plug, then magnatized it to catch any metal that could fall into the engine and it came out no problem. Good luck with it ,I know the feeling.

    dealt with that prob before unfortunatly we had to pull the head. It was not on a FXho though it was a VX110. I have never put a torque wrench on a spark plug i always just put some anti seize on there and use a 3/8 rachet i just run them down untill i feel the washer crush then just a slight bump past that.

    All i am gonna say though is i wish you luck with getting that out without removing the head, ours would not budge.

    assuming you grease the threads with a anti-sieze compound material

    a EZI out will do the job easly

    Thanks for the advice guys...got it out no problem. Used an improvised tool, a TORX socket and lightly tapped it in with a Mallet. Came right out with the socket. I have to thank the jetski gods that the ceramic core did not break and make this task a lot harder!

    turning it over would be a big no no, best advice would have been to vacuum any of the rubbish out.

    Good news! Now you can wipe the sweat off of your forehead. That is the worst feeling, my heart dropped when I snapped mine.
