400ex Jetting Question

[g14classified]

ok ive been looking through here and i cant really find a straight answer on jet recomendations i would greatly appreciate any recomendations or advice you have to offer

the mods are in my sig
i also removed the airbox lid as i only ride in dry conditions

also im not sure what its called but the tube was removed goin in to the bottom of the airbox

the owner before me also poked a hole in the spark arrestor screen

but the general recomendations im seeing is 42 pilot jet 155 main jet

i also took the spark plug out and it is dry and black

152 main 42 pilot 2.5 turns out.

change the plug, do a plug chop for the main jet.

42 pilot might be a bit rich so tune the f/a correctly.

read this for both of the things described above directions are in there for both the f/a tune and the plug chop.
