humidity

you need humidity, temp and pressure to gain air density

its the change in air density that will affect what was previously 'good' jetting. theres a little more to it but temperature change alone is a 'second' order effect (change in overall fuel/air densities).

record all the parameters for a given day and obtain the best jetting from looking at your rpm data (err on the rich side for safety of course).

youll find a strong link between air density and jetting.

you should be able to find air density calculators on-line

remember that jets vary despite their markings
