I'll suggest that the previous owner or their 'mechanic' had left the wing screw loose once & it had backed out allowing dust entry.
I've never had one that was properly snugged down loosen of its own accord.
A younger customer, with beer drinking buddies in his garage, had the fairly large flat washer used on the wing bolt of his KX500 pass thru the carburetor & reed valve assembly of his engine a few days after the midnight servicing, many years ago. (No air filter flame arrestor screen needed on 2 strokes.)
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
