white bros. e-series question

[lil'redrocket]

how many disc does it come with? how many do i need and what main jet for max proformance?

the pipe comes with 12 disks. id just leave it at 12 cuz i personally think it gives the best all around power. i suggest a 155 main jet and a 40 or 42 pilot and move the needle down 1 clip. this will help out a lot over stock jetting. ive also heard of using a 158 main but never tried it so i cant really say how it performs.later

What he said!
I am running a K&N power kit so i used the filter and put 4 holes in the air box, and jetted it to 160( i might be a little rich) 3rd notch on needle and running a 42 pilot for the snowmoblier type wheather:) . i am going to run 18 or might go down to 4 depends what type of riding i am going to do the most this summer:D

I have the better responce with 8 disc. Maybe it's because I have the full system and stock quad.
