As stated in the title I have a problem with the rocker arm screws coming loose.Can I use locktite on them to keep them from backing off or is this not a good idea?

I haven't been into my rockers yet but isn't there a lock nut on the adjusters? I would just make sure the lock nut is snugged up tight after you make your adjustment.
Chris I have done exactly as you stated but they are coming loose still
I nhad one that almost totaly unscrewed off the nut when I was riding the other day.

what's a rocker arm screw?
Maybe Im using the wrong name to describe but its the screw that has a nut on it for adjusting the valves lash.
ahh right
i dont have one, was just curious what it was but it belongs to your magical shimless valve lash adjusters

You just tighten the jam nuts.....tight.

I had the same problem, brought up here: http://www.xs400.com/forum/showthread.php?t=11283
The adjustment screw and nut backed all the way out of the rocker arm and were sitting in the top of the case.
I think getting the lock nut nice and snug will solve the problem.

I remember when someone else had the problem but I dont remember how they solved it?Usualy I tighten them down till they are snug then a little more.Its only happening on the right side exhaust valve.
I'd buy new nuts and screws as the thread may have stretched causing the problem
Thanks Drewpy that would explain it,so the next question is do I removed the valve cover completely to change them?
Also can a rocker arm be taken off for inspection with the head still on or does it have to be removed also?
Im also going to check and see how tight these nuts are after a while.

nah, just take off the cam caps. Just don't drop them down the engine
I`ll see if I can get to them tommorow nd thanks for your advice.Im going to inspect the threads and the tips of the rocker arms for wear.
Didnt have enough time today I was busy working on my main transportation vehicle.I replaced both upper control arms,ball joints.
