[timo_d135]

hey guys i have a 99' 400ex with a DMC double barel full exhaust, sparks 6 key, iridum plug and k&N.

the guy i bought it from had it jetted at clip 3 one the needle and a 142DJ in it

my question is wouldnt a 142 b too lean...

sounds just about right to me. dont forget dj stuff is labeled smaller than the keihin stuff.

a 142 is a 155 which is fine for what you are running.
