jetting for twin air power flow

[71_400TRX]

i just got my twin air power flow kit in that converts everything to cage/wing nut assembly, very impressed with this product, but to get the most out of it i would like to jet my carb to match it. I have the UNI Air Vents on my airbox (lid is on) and the baffle out of my stock exhaust, plus the Twin Air Power Flow kit. what jet sizes would you reccomend?

P.S.-Elevation- Western Nebraska so probably pretty low.

Thanks

We assume you have a 450r since this is the 450r section but what year?

I would use a 160-165 main jet depending on how many vents you have in the lid with the stock pilot. You elevation is 3940 feet.
