Dial A Jet for KTM 450

First time using Dial A Jet system.
Running CT Racing Exhaust with Cam and dial jet with 150 main. Ran great until I open the sided of air box and mixed 50/50 with 91 octane/111octane.

Now seems to sputter full throttle in all gears. Tried adjusting dial and change main to 155.

Any help will be greatfull.

Thanks

Think I figured it out.

Got rid of the 111 octane and up the main Jet to 165. Had to turn dial a jet to full fat. Could probably use a 170 main but will get alot hotter this summer in Oklahoma.

Opened left side of AirBox with five 1inch holes and had to up the main jets 3 sizes.

Will test it more tonight when the boy get's home.
