I assume you are buying grips for the Harley. Unless the sportster is very different than all the 88s and 96s then you shouldn't have to worry about them falling off. All the Harley grips I have seen are pre-glued at the manufacturer to a base sleeve surface that requires opening the two halves of the handlebar switch padcovers to mount the grips. Now, that being said I have seen a couple of the grip chrome outer surfaces come off, but the bike is still perfectly operable because the inner sleeve cannot come off without again splitting the control pad covers. And since it was supposed to be properly glued at the factory both occasions I'm aware of resulted in a new set of grips for free. As for the Kurys; if they do not list a specific model for the Harley then you are now dealing with peeling the old grips off and doing your own gluing in place for the new ones. The dealers sell contact glue designed for this but those and most suitable glues dry in about 3.2 seconds so you had better be ready, quick and get it right the first time! I know this from mounting some nice grips on my Honda GW and if I wasn't a big strong, quick thinking guy with a high pressure air hose immediately available I'd have been cutting the @#$$% things off and still cursing them. As far as screws, anything requiring screws or bolts on a Harley; BLUE LOCTITE is right for it 85% of the time. If it's cotter keyed you won't need the loctite. If the manual calls for red loctite, use it. If it just says tighten with any torque other than finger or hand tight, then Blue loctite is probably a great idea.
