My predator has been sputtering at mid to high rpm, my guess is the main jet needs to be bigger. What do you guys think?

Mods are:
governor removed
arc rod
mod 2 cam
arc flywheel
18lb springs
1.3 ratio rockers
mudboat pipe
hi-flow filter
 
Low speed is stock i guess, i took out the main jet and drilled it out some so im not very sure what exactly the size would be.
 
If you running gas drill the low speed with a #77 drill bit and the high speed with a #65. The best way to do it is to start small and take a plud reading after drilling.
 
Correct. When drilling make sure that you only drill through the jet and not the entire plastic piece. You do not want a hole in the top of it.
