Yea yea...another 400ex jetting thread

[nitrochicken]

Searched a bunch but want a good starting point when this mild build is done in a week or so. It's a 00 400ex with a stage 1 Hotcam, UNI filter with a CFM airbox with no lid and a HMF sport slip on...everything else is stock. Will more thank likely get a kit from jetsrus.com to have some extra stuff laying around. Thanks in advance for the info guys, this is really a great site.

155-158 main with about 3.t turns out on the f/a screw and leave the needle. I would say that if you just bought a 155, 158, and 160 you would be fine. Start with the 160 to make sure it is a bit on the rich side then you should be able to lower it down to a 158 imo. I think that will get you close if you are around 1500 ft or less.
