jetting for a 425

[voges]

i am putting a 425 national kit and a tc mx cam in my 400
i need some jetting ideas
i have a fmf powercore 4 pipe and a
K&N air filter
if anyone runs somthing like this
if you could let me know what you run it would be helpfull

i would try a 170 main
and a 42 pilot
these are all standard jet sizes not from a jet kit.
now move your needle jet down 1 clip towards the point and remove your airbox lid. this should be pretty close and or a good starting point.
