It's my first time removing the end cam covers and valve covers. Do I need to replace the two gaskets or are they re-useable? Thanks in advance, Arty

They last forever in my experience. Just be careful when removing and reinstalling.

Have ya got a valve chatter?
If not, why ya mukkin with them?
Instead of fartin around with the valves, just go riding instead. You'll feel better after the ride than ya will after wrenchin.
242K+ miles on MGM and the valves were adjusted ONCE, on top of that, they were all in the range as specified in the service manual.

+1 mine were adjusted once at about 90k when I replaced the timing belts and they were in spec.

Why are you guys adjusting them if they are in spec? I believe I would have left them alone if they were not out of spec.

I've never felt the need to adjust the valves on my Valkyrie.
Over 118k and they never made any noise and it never had a
skip or diminishing idle problem.
No indication that a valve needed checking.
With my history with Honda motorcycles I had, and still
have, complete confidence in Honda's ability to make
motorcycles that will last a lifetime & needing very limited
to no unusual work performed on them.
Anymore, most all modern cars, and most all motorcycles
are in the same consideration - just Honda motorcycles are
and were decades, ahead of their time.

I just checked mine because I bought this bike used and it now has 71k. A few were off slightly and I brought em back in. The main point is note on the cover gaskets the areas that had gasket sealer/silicone and add a little to those areas on re-install. I did scrape the old stuff off of the heads.

I check mine once in a while (30K miles or so) just to be sure all is well, but like others have said I rarely find more than one or two out of spec, and even those are within .001" or so.
Actually, loose valves that clatter a bit when cold don't cause the damage that a tight valve can. When the engine heats up, too little valve clearance can tighten up to the point where the valve doesn't close completely. This lets burning fuel pass through the slightly open valve during the power stroke. By not closing completely the valve also can't dissapate heat through the seat and cylinder head. These conditions can lead to a burned valve. It usually happens on the exhaust valve as the intake gets cooled by the intake charge.
Having said that, burned valves are pretty rare on modern engines and I've never heard of a Valk with the problem.

Not enough lash/clearance reduces the amount of time the valve has to cool. The cooling is accomplished during the time the valve is on the seat. Not enough cooling is what causes a valve to 'burn' and therefore that valve is usually always quiet. The ones you can hear are the ones that are getting cooled.
