Up the main one size. Maybe two. Possibly back the air screw out 1/2 turn to 1 turn, its your machine, you know best brother, Jetting is one of those things you need to mess with to get down, i have a uni filter,leo vince slip on, 150 main jet,3 turns out on the fuel screw, 22.5 pilot, third clip on the needle, all dynojet, no lid.

What is your elevation?

You could start with a 165 main, needle on the 3rd clip and a 25 pilot jet with the fuel screw 2.5 turns out. From there just start leaning out your main jet till it pulls the hardest. From there I usually like to go back one jet richer just to be safe.

elevation is sea level and i just want to buy a single jet or two, is the main jet all i need to actually buy to do this?
