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

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
