Ok, I have a...
1999 Honda 400ex
White Brothers E-Series Slip-On
Stock head pipe
K&N Air Filter
Outerwears Pre-Filter
Stock Airbox and Stock Lid ON
My location is as follows...
Currently 65-90 degrees in the summer about 80% humidity and an elevation of 1378 ft.
The type of riding I do is hard/fast-paced trail riding, I usually ride with other 4x4's and ocasionally go through seat height mud/water, that being the reason I can't modify my airbox. I am not sure what my current jets are but I do know that the previous owner had stock exhaust and the K&N air filter and outerwears with a stock airbox and stock lid on and he rode at mountain elevations and modified the jets. So I'm assuming he put smaller jets in, and at my elevation I can deffinately feel constant back-fire when the machine is cold and doesn't idle at all when cold.
I plan to buy a jet kit from www.jetsrus.com, I would like to have a general idea of what jets to put in to start with and needle position. I haven't installed the pipe yet so I'm not sure how many plates I will be using but I will probably have all 12 installed.
Thanks alot for your help.
