2002 Honda 400EX jetting

Ok so I'm new to jetting and I was wondering what sizes to use on my bike. I have one dyno jet kit and another kit that comes with some Keihn jets.
The dyno jet kit was given to me. The bike is stock except for the Procircut t4 slip on exhaust. What sizes should I use? What jets dynojet or Keihn? My elavation is 3,200 feet to 4,000 above sea level. I also plan on running no lid and stock air filter. Thinks for any help.

Dyno jet uses a different jet size numbering system than Keihn.
The dyno jet kit has a troubleshooting guide for fine tuning.
Follow the instructions in the dyno jet kit.

Can I have more info on this?
