    Sparkplug stuck in cylinder head.

    Everything started when my ultra began to miss spark and did not run smooth. After reading here i figured it had to be the sparkplugs even thought total enginetime is only 6hours.

    4th 3rd 2nd plugs was easy to remove but cyl. nr 1 was stuck so i tried a little harder and you can se the result from the pictrues.

    is this a common problem on the 250x and whats the best way of removing the plug that's stuck?

    its only common if someone doesnt use neversieze on the threads, tries to remove when hot, overtightened them , or left them loose and the threads have bound up ,
    So anyone of these can be common

    Waz

    I have had to do many repairs like your on customers ski, And just so you know the head stays on 99% of the time when I do them, you just need the right tools and skills

    what's that?

    my engine was cold (15C-20C)
    is it harder to remove sparkplugs when the engine is hot? alu expands more then steel when heated? right?

    Don't sweat it....I've had this happen on several occasions on friends bikes, and once on mine. Get the right size "easy out" and MOST of the time it will come right out. The easy outs are pictured on the right side below. If that doesn't work, get a friend or someone who can weld and have them drop a bead on a nut on top of the plug ands remove it that way. Take a deep breath...it SHOULD come out fairly easy. After that, definitely line the threads of the new plug with a never seize. Good luck. Keith

    This may sound weird but here it goes, I took out one of mines with a small tipped screwdriver tapped into the broken piece and slowly remove. I was lucky, but it was a very exspensive PMR9B one!!
