03 300exc stock jetting

stock jetting is:
175 Main
45 Pilot
NOZH needle in the middle (3) position
6.5 slide
Airscrew 1.5

This should give you a starting point, but at your altitude- leaner than stock will work better.
Enjoy your 300, they are the best. Get her dailed in and you will not believe how good this bike is!
