Let's see here........ :think:
40 pilot
140 main
stock needle 2nd clip from the top
no air box lid
FMF pipe and silencer
Boyesen 607's
This is my "summer set-up" for about 75*F and aprox. 700 feet above sea level.
good luck! ;)

JMHO - but that seems lean to me for a suggestion for another to use. Try 42 , pilot, stock needle in #2, 145 main first.
