Hey all, I have a 2002 660grizzly and the spark plug boot/wire keeps on popping off. It’s not seating very well anymore onto the plug. I guess the clip inside the boot is worn where it won’t grab the plug very well. Is there a fix for this or should I buy a new wire/boot?

Welcome from Colorado.
Make sure the boot is aligned with the head when pushed down, there is an irregular shape to the boot which fits into the head as a seal. If not the boot might not be fully seated, thus your problem.

Ok I’ll try that. I did have the spark plug out and tried it a few different ways and it’s very easy to put it in and pull it out :ROFLMAO: Should it be that way?

Try re-crimping the clamp inside the boot, or are you leaving the threaded electrode of the plug exposed, or installing the thread cap?
My boot clicks firmly to the plug.

When I took out the plug the threaded electrode was exposed. That’s probably why it’s so sloppy?

That could be it, depending on the boot style.
