Tomorrow im gonna try balance the carbs with a Vac gauge as its running rich then plugs oil etc. Such fun ;D ;DRunning rich has little or nothing to do with unbalanced carbs.
This would be my working order:
Let camchain tensioner adjust itself (if needed)
Check valve gaps.
Check ignition:
a. breakerpoints gap
b. check timing stationary and fully advanced
c. doublecheck a and b
d. Visually check for arcing whether at the breakerpoints or between plugwires/caps and head. When in doubt replace plugcaps by new ones.
d. Fit new plugs.
Verify fuel level is unhindered and level in the floatbowls is correct.
Is airfilter OK?
Check for airleaks at intake boots and where exhausts connect to the head.
Take notes of what the airscrews are set at/Check airscrews are set correctly.
If the bike was inactive for a long period, check at least the slow jets are clean.
When all this is done, there's a good chance you can abstain from vac syncing.
Beautiful bike!

* See pic where you can find the carb number. In this case 087A the carb that was on the CB550K2. Your K1 originally had 022A.

It's the electrodes of the plugs that are sooty , I've referenced them against the pics in the manual and it definitely says it rich.
Dave - not sure how much you've run the bike but I didn't change the plugs, so the soot could be from the previous running. I'd suggest a new set of plugs to be on the safe side & you can asess how it's running on the set of 'Gerben' carbs just fitted to it. Also, fit a new air filter as well..James.

The carbs are 087A ,so would that make any difference as Deltarider says they are K2 will the adjustment be the same .Why the K2 got a different carb number - 087A instead of 022A - is still a mystery to be solved. Studying the various CB500/550 parts list some years ago and this one in particular: page C10 in http://www.honda4fun.com/pdf_parts_list/pdf_spac550/CB550-K0-K1-K2/CB550-K0-K1-K2_04.pdf, I detected one difference that would explain the new carb number: in stead of airscrew pn 16016-323-004 that we know of the CB550 and CB550K1, the parts list mentions for the CB550K2 an airscrew pn 16016-390-004. Ha, that must be it! I thought. BTW, it's the airscrew with a solid tip and not cross drilled that we know of the CB550F models. But... sofar not one owner of 087A carbs has reported, when asked, that he indeed had that airscrew. They all had the old airscrew, with open tip and crossdrilled. Strange. Anyway, since then I have made it a habbit to ask every owner of 087A carbs what type airscrew he has and that now includes you. Please unscrew, after noting what position the airscrew is set at ofcourse, what type of airscrew you have. Mind the little spring! In the pics below airscrew 16016-323-004 and 16016-390-004.

I’ll take that as a compliment Steve. I’m slowly bumping up the average age as each year passes..

Here is a pic Delta of screw.Thank you. So far I have not heard of anyone that has/had the other airscrew (16012-390-004) in his 087A carbs as page C10 in the parts list clearly specifies. Strange. Another reason to give the 087A carb - that is further identical with the 022A carb - its number could be that the needle was hung in a different position. Actually that's the only thing I can think of, but I'm not sure if that in itself would be enough for a different number. So... still a mystery.
Man, that is a lovely bike.
