I can ensure you that both ways can let you down and find your self swearing on the road side for couple of hours...

a. better fuel mileage
b. cleaner exhaust

In theory a 10-12 % better mileage
on the road it varies a lot ..mostly weather dependent...
The best mileage i could get was when i used the PC III...leaned 2% lows-mids and leave 7000 and above untouched..got 40 50 kms more..
As for the exhausts emissions yes assuming you keep all the original systems intact and in mint condition..
I believe that an experienced hand and keeping the revs in torque range can distinguish the difference

Of course keeping yourself below 7000rpm will keep your emissions to a low level, but honestly how often does that happen ;-) Besides, not everyone has an "experienced hand", and as such rely on technology to control those things.

Another thing (as a difference between Carb and FI), is that the Carb models have more raw HP power, which might result in higher insurance costs (depending on how the rate is calculated between engine CC and HP)...

Running the bird on 6000-6500 on last gear gives me 160 km of speed ..more than enough for touring and being loaded with luggage..once there all i have to to is keep steady throttle under 30%..and the rest belongs to the O2 sensor...

The carbed birds have slightly different distribution of power due to the different cam lobe lifts and different ignition timing..the honda press kit gives bigger volume for the Fi bird tank but carbed birds lack of internal fuel pump and filter

I used to have z ZX-11 :huh: (wtf wuz i thinking?)... you have to touch the carbs and all that things you know.

FI!!!!!!!!! You forget `bout everything... Just pop in da bike and ride!!!!!! :smilebig:

Hmmm..yes...unless the sensor havoc takes place...
