For one just the valve cover has to come off, for the other the cams have to come out and different size shims inserted to bring it back into spec using special tools.Also on I-4s there is not a lot of space under the back bone frame to work.

Then again, some people have natural mechanical aptitude and are handy at things like that, while others are not. My younger brother has always had a knack with mechanical things and can work on and fix anything, but he can barely draw stick figures and can't properly diagram a sentence. I'm terrible with tools, but am a fairly talented artist and have co-written a book, been published in 7 national and International magazines and was an associate editor for a magazine for a couple of decades (although it was mostly a figure head title as I didn't have to do any actual editing lol).

He had dark hair, dark eyes and is left-handed, I had blond hair, blue eyes and am right-handed (both gray now). We are completely different, but we both love riding motorcycles, and worked in the same motorcycle shop for years. He as a mechanic, and me as a parts/service manager. Different skill sets put to different uses on the same product.

The "Observed Valve Clearance" started by Pterodactyl many years ago, it is a table of actual check results by members of the forum at various distance ridden points and the results found.
Based on that I made the decision to not do the check at the interval recommended.
My chain and sprockets are near to change out but not there yet at 60.000km.
I change the oil at 6.000km as per Hondas guidance for my year model, I understand it is now 12.000km stand to be corrected.
I have a recollection of a bike having 160.000km on the clock with one adjustment (still in spec) in that time but all other checks in Spec.
I hope that on reflection you might retain your CB1100.

Valves will tighten up , not loosen up on these bikes as miles go on (typically unless theres a mechnical failure). an early indicator of this is loss of compression on one (or more) cylinder. a down and dirty check is a warm engine compression check on all 4 cyls. if one is lower than the others beyond the allowable range, (20-30 psi i would guess) good bet that cyl needs a valve/shim adjustment. (if all else is ok). .02
