Thank you both for your great help. I think I have now worked it out.
I think this is how they work - if I am wrong please let me know.
Canyon - sorry for highjacking you blog, but thanks for your help.

No worries man, glad it helped.

Waiting on a thing or two I forgot to order.  Looks good under the valve cover so far.

I made a quick spreadsheet to log all the important info:  (yes, some have surprisingly little clearance)

Then lots of time with the feelers.  It's a royal pain to get some of them in the right position to measure.    The lobes on end of each cam are a "gimme" at least.

Is it looking pretty tight in there or do you have some slop?

26,017 miles total, and about 1400 of those are mine.  It doesn't look it's been opened since Mr Yamaha built it.  It's pretty tight.

Man, that's good to hear. I really think that you got a good one on that deal.

It's good that nobody had been in there and monkey fingered the insides but they are way too tight.    The book says valve clearances are to be done by 26k miles.  (I think it's about every 14k on the Zrx.)  It's a good thing I didn't try to squeeze more miles out of it before doing this job.  The chart show my initial run through the measurements.  I always do it twice on the initial check.
