I'm wondering what you do-it-yourselfers have done regarding valve adjustment on the 4-valve bricks? I've done it myself on the old 2 valve bikes; there was once a kit with spare shims circulating the community. The 4-valve bikes seems to require the PITA cam removal, but even once you accomplish that, do you just go to the dealer to buy the shim sizes you need?
The typical approach I've seen in scanning postings has been to ignore the issue altogether, and go on the theory that they never get too far out of spec. I've just measured mine (2003 K12RS w/ ~50k miles, never previously adjusted) and found all the exhaust valves in spec; three of the intakes were low. The worst was at 0.004 for a spec of 0.006-0.008.
Thoughts?
