is it possable for you to fit up a wide band AF gauge to set the carb up...
i thought I had the Koso/OKO right... lot stronger power though the whole rev range
motor ran great everywhere...
but once the AF gauge was fitted... god dam it was rich... these carbs seem to run very well on the rich side...

my AF ratios are after setting with the gauge...
idle... 14.3 - 14.8
light cruse 13.7 - 14.2
light acceleration higher gears 13.2 - 13.6
acceleration from 1/3 to 2/3 throttle 12.9 - 13.4
WOT 12.4 - 12.9... see the power jet really richen up the mixture at
full throttle..

edit....
these numbers are still a tad on the rich side... but thats what i want
my bike is never at a cruse... on & off the gas hard all the time accelerating
or brakeing.. A/F ratio is set to suit what the bike is used for...
thats the great thing useing a A/F gauge to set the jetting..

i had to change the needle to a leaner one "slower tapper" to
get the mid range ok...
went from a 1mm point to a 1.4mm point...
mikuni needles seem to be the best match.
57mm long with a 2.5mm top DIA...

A A/F gauge is worth useing.
What you think you have & what you really have can be 2 diffrent things...
