400ex jetting

[ridina400ex]

i cut the baffle off of the exhaust, cut hole in my airbox and run a twin air filter. The Elevation i run in is around 1000 meters and is usually 20-30 degrees celcius out. I want some opinions as to what i should run for jetting.

try a 152 keihin mainjet, 42 pilot jet, and 2.5 turns out on the fuel screw.
