What Jets are you running on your 400EX
#1
As you can see below I have done a few updates to my EX. Lately I have been playing with the jetting. I had put a 150 in it when I piped it and sence then I have learned a little about jetting. When I checked the plug it was pure white. I started bumping the jets up. When I got to the 175 it ran great, the 180 ran good and the 185 ran bad at full throtle. I think that I'll go back to the 175 even though the plug is still a little white.
Can any one tell me, do you think that I'm on the right track.
Also I have not change the Pilot Jet yet, I was told that a 46 would help out.
