My CB750K does the same thing. The longer I leave it, the worse it
runs right after I start it.
I blame this on a leaky valve stem seal. Oil seeps past the seal
while the bike is sitting, and gets diluted with fuel and burned
off when the engine is running. My bike blows blue smoke from the
exhaust when I close the throttle, too.
My solution to the problem is to keep putting oil in, and wait for
a convenient time (after I fix my car) to pull the cylinder head
and replace the seals (and re-grind the valves, and dial in the
jetting, and other tedious tasks I don't want to think about).

Check the battery. Old Honda's (I've had 72' SL350, 76' CB360T and
now a 76'CB400F) and you always loose 1/2 a moter (1 coil) with a low
battery. THe SL350 had a bad rectifier (sp?) and it would drain the battery
if I didn't disconnect the battery when the machine was off (used a switch).
One day I left a friend's on it running on 1 cylinder and about 2 houses
down the road the 2nd cylinder kicked in exploded the gas is the exhaust
and blew it wide open imbedding carbon in my arm... fun (I didn't own a
leather yet, it was summer... I was stupid, no jacket). Boy was that fun...
But all 3 of the bikes lost a coil if I let the battery get low, I'd start
there.
good luck

ps. Permatex fixed my seal problem. There was no gasket.
