im going to get a wb carbon pro n im wonderingwhat jetting im going to need for it

For a 400ex its pretty simple. Go to your local Honda Dealer and pick up these three jets.
Keihin- 155, 160, and a 165.
That should be a good starting point, you shouldnt need to go any higher. Make sure to check the spark plug color after you jet it to make sure its not running to0 rich or too lean.

While your in the carb you can always put in a Keihin #42 pilot jet to make it easier starting.
