I have a 2002 KDX220R. After reading the
recommendations from the Hop-Up Guide I've done the
airbox mod and have just bought a FMF Gnarly Desert
pipe and Boyeson Power Reeds #607 for it (cannot
wait man :yeehaw: ). I have not modified the 33mm carb.

So if I've read right I should be leaning it and jetting
with a #40 Pilot, #142 Main and stock needle 2nd from
top position. This calculation was arrived at with
the presumption that stock is #42 Pilot and #145 Main
(not sure if I've got the stock numbers right).

This is my question ... are my calculations correct
for our elevation here of roughly 2300 ft above sea level with an average temp locally of roughly 23-30 degrees C?

Thanks in advance :bang:
