rich or lean

Does adding a white bros slip on and removing airbox lid make the bike rich or lean?

It will run Lean

yep, leaner

should i adjust the fuel mixture screw in or out?

You need to fit a bigger main jet and probably a pilot jet and raise the needle.You should learn abit more from the jetting section.

Go to Indy and performance mods for carb jetting. Its good stuff. Dont ride your bike without making the carb changes too in addition to the Pipe and airbox. You will be very lean. I am hearing a JD jet kit is the best for our steads. Thanks, Jason
