Jetting for 03 250 EXC

[muddobber]

Will be in Colorado in a few weeks and was wondering what jetting
you guys are using for 8000 ft elevation. My jetting should be close to an 02 and 01 250 EXC also. I use the head off an 01 on my 03.
Any help is appreciated.

What needle are you using. I plugged numbers into the JD Jetting guide for 8000 ft, and got 42 pilot, NOZG on #1 clip and 168 main.

I run an I needle from my 01. 180 main, 48 pilot and 6.5 slide. I think the
needle is a N3CI. My notes are in the garage. I don't like the stock needles
from the 03, they seem too lean to me. Tried the H needle from last year but
the I works better on my bike. Thank's for the help.
