2012 8v rollered followup -

After Pete handed bike back to me I have covered around  3000 kms since then. At 1000km (post Roller) did an oil change and checked clearances, left side a fraction looser than right - RHS close to specs. TPS 4.6 and CO2 around the 12 mark. Bike pulling like a locomotive with a 'different' feel to the rumble around 3-4k rpm from pre-roller days.
At around 3000kms noticed idle lower than usual with an occassional slight 'mis-timed' feel, put the PC/GuzziDiag back on and checked TPS, was 4.6 .. CO2 +12 .. took CO2 down to +4, idle worse ... bumped CO2 up slowly and for the moment left it at +28 where idle is regular and exhaust has a 'fuller' sound .. was sounding a bit soft before... If I understand this correctly I have enrichened the idle? More CO2 in the exhaust = richer, less CO2 = leaner?
Riding bike after this has made an immediate improvement from 1000-3500 rpm, is mechanically (maybe) a little quieter, throttle response off idle is tad brisker and stronger. The fuel usage calculation shows I am using a tad more fuel in cruise .. maybe the mixture was running a bit on the weak side with CO2 at +12?   
A very HAPPY Norge pilot loving his Guzzi.   
Replaced both front and rear tyres at the same time - first ride and nearly dropped the thing on a tight slow speed corner - bike is so responsive that oval tyres lacking a flat spot like older tyres tries to make the road climb up that oval profile!

Hmmm, shouldn't need to have that much fuel added but Norges are few and far between here so it's hard to gather data. If it comes back we could maybe do some log work and Mark can tweak the map.

With the CO that high what's the idle speed?
