Don't use threadlock for plastic mounts. Bolts are cheap, but if you have a bolt spin a mount, it screws up all sorts of stuff. Gas tank, radiator shroud to radiator and rear fender bolts thru air box all have deals that I call "body nuts", but no doubt are called something else. Spin a mount in a gas tank, and its time for brand new cuss words. (and a tank) 500's do need lock tite. Mine seems to fling the bolts on a regular basis. The trick is to use it in the right places, Also take note when bolts are hard to withdraw because they are already loaded with it. Double doses may cause the bolt to seize and break.
Congrats on getting it running...
