I recently bought a used 400ex and I went to change the plug today and after quite a while of working with it,it came out.Unfortunately when it did,it brought the threads out of the head with it:mad: .Always use a little anti-seize on the spark plug threads.......aluminum heads aren't very forgiving.

hope the guy before you regularly greased the swingarm bolt and rear brake lever too or you'll be in for a hell of a time ;)

what are you going to do about the spark plug thing?

The swingarm bolt is good.............already checked it;) .As far as the plug goes,I am not a really big fan of helicoils in plug holes so I will probably just look for a used cylinder head.

Yeah,I have seen it happen on several automobiles myself over the years.It's never a good thing when you go to loosen a plug and it starts to move then immediately locks up:ermm:

Actually,the plug didn't look too bad.I was just doing some routine maintenence on ot since I had just gotten it and wasn't sure how long it had been in there.Oh well,you don't know what it looks like until you take it out.........I'll get 'er fixed:macho ;)

my modo is dont fix it if it aint broken. if it is broken get out the hammar and zip ties.

definetly not the best thing to do. main reason for that being my modo is my cash flow situation.

It looks like the engine had a bad case of detonation. The aluminum exploded and stuck to the plug, pulling the threads with it. When i bought my 400, I took a lot of things out, ncluding the plug, air filter (checked for dirt in intake) and just gave it a good look down.

The aluminum exploded?Not hardly,there was no signs of detonation on the electrode portion of the plug.It just seized up in the threads.

Well, like I said it was just routine maintenence on a quad I had just gotten and didn't know any history on as far as when anything had been replaced.No matter when I would have pulled it out it would have still happened.
