Alan, make loctite and your KX5 ( or any off road machine ) friends!
I use blue loctite on everything on my bike. The blue loctite is medium strength and removable. Works great. Use it on your tank, seat, side panels, & everything else. I had my 125 racing buddy laughing at me when I was putting my bike together, I had my BIG bottle putting drops on all the bolt threads. One more thing, it only takes a drop on the threads to work, any more is waisting it. I hope this helps.
