What jetting changes can he make?
Drilling the airbox cover any good?
The cheap stuff is what I'm after, easy stuff that sees gains.

The best thing he can do is keep his valves adjusted. They automatically tighten on the Raptors where other machines they loosen. I just did 3 machines in a row with the same issue.
Machine 1 had 65lbs of compression before and 165 after.
Machine 2 had 94lbs and 135 after, and machine 3 had 105 before and 190 after.
Performance was night and day different of curse along with easier starts.
