400ex choke removal

[Puff Daddy]

I've read the instructions in the Tech Artical & it says to use the 42 pilot jet.

I was wondering if anybody knows if i can use a 45 pilot instead of using the 42?????????????

Would it perform real good with a 45 pilot with the choke removed????????????

This is my final and last question....

Is it okay to run a 155 main jet with the 45 pilot jet with the choke removed & would it perform good????????????

:D :devil:

All of your questions depend on your motor mods.

1995 300ex

motor mods: size 13 piston, with a race cam, & super oil cooler & a 400ex stock carb with the choked removed & running a 155 main jet & 45 pilot jet...........

45 might be too much for the 300ex motor. Only way to know is ride the dam thing. :blah:

Uh...what is a size 13 piston? I would guess the 45 is too rich.
