Sparks exhaust jetting

[pineway]

I just got a x-4 sparks exhaust for my 300ex. I was wondering if anyone is running what there jetting is set up at? Any help would be appreciated. thanks.

id start at 3 to five sizes up on the main. Try one or 2 up on the pilot jet. Then screw around w/ the fuel screw. This should be a start anyways
