The stumbles
Am i right in saying that it is common for stumbling/surging between 5-6000 rpm and what is the fix?
Completely stock 01 12r (at the moment)
Don't fancy the PC 111 after searching the forums. Did i read that the akropovic will bolt on and does not need the PC111?
Sorry too many questions!

check your vacuum sinc on the throttle bodies
maybe throttle position sensor
akra can run witrhout pc3r but mine appears to run better with the pc3r

NOTHING WAKES UP THE BEAST LIKE A FULL EXHAUST + PCIII + RACE AIR FILTERS

I have an Akrapovic on my 2002 without a power commander, never put one on and never will...
I use to have a 2000 with a Muzzy pipe, it was not as smooth as the 2002...I had a custom map from Orient Express but still had the stumble at 3000 and a flat spot at 5000...When I DragRaced it, there were no problems as I throttled to redline...It was only a problem holding rpm in those spots...Then the bike started running worse and found that the PC went bad dumping lots of fuel, I had to change the oil, there was so much unburnt gas in the oil...Some 12s were smoother than others back then!!!...But now the 2002-3 are better and the 2004-5 being even smoother!!!
Never used the PC since and when I was riding the 2000 without the PC the stumbles and flat spot were not as bad as with the PC...
Put the pipe on and change the gearing to 17-47 and that will put the stumble and flat spot down low...Now the 12 will be smoother for street riding...

BMC race filter is good, 4 degrees of ignition advance on the rotor is good
