Remedying the problem usually involves removing the carb, thoroughly
cleaning it, inspecting the coasting enrichener diaphram for the
slightest pinhole, and then reassembling it and seeing if the bike works
better. Changing the jetting without doing the cleaning first is a waste
of your time and money. If the bike is bone stock (air filter, airbox,
exhaust etc) then the jet kit is totally unnecessary.

The pilot jet is clogged, most likely. The carb need to be removed,
stripped down to the casting, and then soaked in a (very, very nasty)
carb cleaning solution.

After a soaking, you rinse it with water (or whatever the directions of
the particular cleaner you bought recommends) then blow out the
passages, particularly the pilot circuit ports and where the pilot
mixture screw goes, with 100psi compressed air.

That's not the main jet. The mixture screw you are trying to reach is
the pilot mixture screw. sagebrushmachine.com sells a very good tool for
adjusting it with the carb installed.

Don't call Kawasaki. I think the guy who designed the bike has died or
retired by now anyway. Asking questions on this list will get you
answers from people who have been riding and maintaining KLRs for many
years. Some people are on their third or fourth KLR, some own three.
