Performance & Setup Notes
Jet size choice should be treated as a tuning decision rather than a one-size-fits-all part selection. Conditions such as temperature, humidity, fuel, oil ratio, track grip and engine setup can all influence the appropriate choice.
If you are preparing for race-day setup changes, it can be useful to keep a sensible range of main jets on hand so you can respond to changing conditions.
