wb e-series jetting

[rooster_20]

i have a 2002 400ex and i lost the papers for the jetting specs that i need in order for my pipe to have maximum performance gains any links or help would be greatly appreciated

[cals400ex]

with no other mods on the bike besides the slip on, i would try around a keihin 152 mainjet. however, the temperature, elevation, etc all makes a significant difference.

thanks i live in eastern kentucky so however that would change the elevation and stuff. do you have any ideas on a site that would have the jetting according to elevations and other stuff

Rooster, where are you from? Im from Mason Co.

[cals400ex]

a local air port or by getting on the internet and typing in your town and state on google or another search engine should be able to provide your elevation.

I live in bledsoe almost on the leslie county line. My other mods are my power air filter that came with my pipe

I really dont have that many mods i just got my 4 wheeler last year i started drag racing at a local track called the outback track in barberville if anybody has herd of it my elevation is: 1211 ft / 369 m for those who were interested in my jetting problem if i bought the K&N jet kit i found would it include all of the things necessary to make me any bit faster and how much of a difference would it make thanks for the input
