YZ400 2 stroke jet help

Recommended Posts

I have a 79' YZ400. I want to make sure it's jetted properly. The things I've added are V-force delta 2 reeds, DG pipe and DG silencer, uni filter in a very free flowing box.

Anybody know what kind of jetting I should use and what I should change?

Is there a universal rule when it comes to adding reeds, pipe, and filter?

Thanks in advance for any help given!!...PB

Here are my carb specs.

38mm Mikuni VM

main #330

pilot #30

air jet .5

needle jet 166-Q-2

jet needle 6DP1
