As stated, no Loctite on bolts that thread into inserts in plastic! I limit my use of Loctite to things that could be a real mess if they got loose during a ride: disks, caliper mount bolts, shifter bolt, etc.,and then only the blue "breakable" kind. I love my KX, (2000 model) and I use lots of anti-seize. Rad shroud bolts, cylinder studs, and especially chain adjuster studs. If you haven't done it, pull the shock linkage, and steering apart and lube the bearings in both places. These were practically dry on mine. A good waterproof grease (I've used both Redline and BelRay- both are OK in my book) will make a difference in the longevity of the bearings.
