Brad Huelings told me that a Kaw in good condition should be jetted the same
in both cylinders.
Good condition may be the key phrase.
I've seen motors with different length pipes on the each barrel as well as
different deck heights. I suppose the crank throws can get out of phase
also. Different amounts of leakage on one head pipe vs. the other ,etc.
Air cleaners can be at different levels of "clog" too :->

Both sides should be the same. The 494rotary rotaxs have a lean problem in
the cylinder that the rotary spins down on. The 440 Kawi and the 493 rotax
do not have this condition.
I use a Kinsler air quality gauge. Numbers for a Kawi are like this. At
100% I conservatavely run 260s(spring, fall type of weather). In the dead
of summer I might get as low as 220. In the winter as high as 300s.
the 500 cc rotax numbers are 3 jets higher than the 440 Kawi. And; I change
jet all day long and follow the weather. 2 jets too large and you'll foul a
plug. 1 jet too small and you'll burn a piston.
The serious guys put in new plugs every session and read them to double
check the Kinsler and EGT gauges.
