There is lots of motorcycle tuning info on the net...

The typical MC carb has three tuning bands
Pilot (low speed) Jet = Low RPM
Jet needle = Midrange RPM
Main (High speed) Jet = High RPM

The RPM ranges overlap so that the low RPM settings taper off as the midrange RPM settings are coming on. And the midrange RPM tapers off as the High RPM settings start coming on.

The Pilot and Main Jets are numbered and are replaced to affect changes. The needle has clip slots that allow adjustments.

Very basic info here... Your specific carb may be different.
