97 Running way too lean

[freud1au]

Was running a bit lean before I fitted cobra six into six pipes.
Gave it a quick Dino after because she would not run under load above 2000rpm.
Ran fine under 2k at 12ppm but above 2k was 18ppm.
I ordered and fitted the cobra jet kit. Came only with needeles springs etc but no jets.
Re dyno and now at 16ppm. When I spoke to the dyno guy he told me that normally the kit comes with a drill to drill out to aloe the diaphragms to lift earlier in rpm.
Does anyone know what the size of the drill is and what size jets I should be running?
I turned my plugs white in under 50 miles

Got a pic of plugs. My plugs are always white and it's only has K&N with pre-filter. No other running mod.

I am running 112.5 main jets with the C-clips one from the top. 6 deg trigger wheel and I/S ECM. Twist it at 5MPH and it  will light up a 205 CT. Main jets I got at the local H-D dealer (thy said thy would work ) but what do thy know

Wiz did you drill the vacuume for the slides? If so what size.

No photo of the plugs. By white I mean from shiny silver new plugs to paper white in less than half a tank

Yeah, little lean.

Did not need to drill anything ! Just a good cleaning !

[freud1au]

Ok I will make a set of 112.5 jets. See how we go from there.
Where did you get  the six deg from

[freud1au]

Ok 112.5 still too small
Ended up 117's
Duck me I thought she went before but now. Wow
Thanks wiz for the info to start me off
