Mike,
My clever solution to keep the valve from falling into the cylinder is crude,
but easy and very effective. It works well on single spring valves, not sure
about the double sping ones.
Simply take a rubber band and wrap it many times around the valve stem
(through the spring) and not it until you're comfortable that it is secure.
Then, using the head of a small brad, work the lump of rubber band knot down
the valve stem so it is wedged against the head. This will solidly keep the
valve in place while you work on the spring, cap, whatever.
When all is reassembled, use the tip of an xacto knife to pop the rubber band,
then fish out the remains with a tweezers or toothpick.
Good luck.

Subject: Exhaust valve spring "caps"
I"ll be as brief as possible.
On my 72, the upper, inner spring cap, (the part that holds the collets in
position), is a forged part. I recently found one of mine to be fractured.
Just
enough remained in position to prevent the valve from being dropped and eaten.
An ugly thought, no?
TRF said "back-ordered" of course. My source in Blighty, after a thorough
search, was unable to find replacements. Then he was informed that Triumph,
because of failures, had replaced the 2-piece cap with a 1-piece, similar to
the
intake valve upper cap. He has shipped 6 to me. (I already worry about enough
things on this stressful little darling).
If you have the head off, and you have the 2-piece setup, you might want to
consider changing to the 1-piece. Opinions, anyone?
I'm trying to come up with a tool that I can insert through the plug orifice
to hold the valve in position while I change the caps.
(Check page 31 in the TRF Catalog).
