The vast majority of jet kit users are inclined to add fuel (more is better, much more is better yet) and inevitably end up on the jetting merry go round.

Marketing for the entire USA (or Euro) keep in mind the factory chooses jets for a wide variety of atmospheric conditions, elevations, etc., even compromised to suit both EPA and efficient running. Hence what is supplied may not be be optimal for you in your specific environment.

Reminder of the old school 2 stroke racing tuners (Erv Kanemoto comes to mind) jetted by changing weather conditions at the track...what worked in cool, clear morning practice did not in cloudy, warm afternoon qualifying sessions....needing changes.They seemed to rejet on an hourly basis and were very good at what they did.
If they failed, engines would blow up (leaned out right to the edge of seizure) or races would be lost (lack of power)

Google Erv Kanemoto, a tuning legend
