This is my dyno chart from a couple of weeks ago. I like the power...but the air/fuel ratio (light coloured line - red line is ideal), is generally way too rich.

I'm using 39mm Keihin CRs with these settings
55 pilots
240 air correction
128 mains
Needle 4 clips from the top

Obviously a dyno run is just feel the power and punch it...but I don't usually slap the throttle wide open...unless I'm impressing the school girls[:p], So we tried just running it under load and it was way way rich (10-11:1)

So to cut a long story short...

Going off the above chart...and the chart below which shows the effect of changes to the carb settings...where do I start?

I've got a shit load of jets....but I got N.F.I [V]
