well I have not been lucky enough to test a high mileage bike BUT on the past 3 with the decompressor removed from the bikes on a cold motor I got 150 lbs on the compressing tester.
bikes ran well on that including the red redditch...LOL
just something for you to try I guess

   I've found something interesting while tearing down the head, and, since we all know good things are worth waiting for, my next post will provide a great laugh for all at my expense.
   And I'm gonna make you all wait. So there.  :P
   Any $64 questions?  ???
   
   Note: I am not laughing.  ::)

Are you going to do anything with valve train while head is off?  I'm asking for a friend. :)

I too had a strange and similar problem that was ultimately the result of the sheered negative ground wire battery connector. I eventually found the problem quite by accident by test riding the bike at night. I was under the impression that the engine alone was suffering from an intermittent miss, but at night it was obvious that all the lights were missing at the same time. A quick inspection revealed the connector had sheered right along its bend line.  Poor design.  I have since replaced the flimsy and highly stressed factory connectors with heady duty lugs.  It seems that this particular location of the bike is highly prone to vibration related issues.  Everyone should inspect their battery connectors, especially the negative end. Good luck to you.

Bert: I expected either a valve issue or rings. Maybe even a holed piston. Already tore the head down, valves inspected and good, springs' free length in spec, and will replace the stem seals when they arrive. Probably ok, but WTF as long as I've gone this far I may as well replace them. Piston's got some heavy coking, though the valve cavity actually looks pretty good. Did a leak check of the valves before disassembly and no leaky. Still gonna clean things up a bit. The barrel looks very good, with all the cross-hatching still showing nicely. No gouges or scratches. Compression apparently is not the problem.  :)

Narada: Push Rods, rockers good. No socket in the head pipe. All the wiring is good. And my TP rolls are way to big for the air box. I'm a good little consumer and buy the biggest rolls I can get.  ;)

GHG: Plug is good. Tight as necessary. Hope you're still alive and kickin' by the time this is posted.  ;)

Wild Bill: Head gasket and valves good.

Mad4Bullets: Thx for the well wishes. Electrical not an issue. Aller ist gut!

Portisheadric: Push Rods are fine, were installed correctly, and still have a mirror polish.

9Fingers: No mice, nests, or poop in the intake system. First thing I checked was the filter on my ACE can.

When changing the silencer to a long reverse meg, I USED TOO MUCH SEALANT![/size]The back pressure was a bit much, ya think?  :-[ [/size]

heloego -- I found the source of your excess sealant problem -- your workbench is overly tidy and organized. :)  PS what sealant did you use?  It looks like it might have expanded when heated.

I didn't have any high temp silicone, so I resorted to that crap exhaust "sealant" that was cheaply available from CMW back in the day.I didn't realize that stuff expanded so damned much!  >:( At least it's easy enough to clean out. Might as well polish up the exhaust port and cavity before I re-assemble everything.  :) So the tube was pitched immediately, and it's high temp silicone from now on. PERIOD!  ;)
