Engine intermitent hesitation

2001, Yosh RS-3 bolt-ons, PCIII

After a couple minutes, when the bike warms up, the engine seems to hesitate (happens in all gears, all RPMs). Seems to be running excessively rich, very little acceleration. Occasionally, the hesitation will go away for a few seconds, and I'll be riding a normal bike. Just installed the PCIII as a potential solution, and after loading the Yoshi map... the problem persists. Any ideas???
 
does it happen only when engine is hot???

read my post (engine stuttering) and try to pay attention if you hear some bubbling noise from the tank when you turn on the key when bike is hot...

if this is the case, you have the same problem of myself
