Aww shit man. I grew up in Casper.

 

Let me see if I can put some light on this for you.

 

Umm depending on how much the lid is CUT. This should get you started and should be on the rich side of things.

 

Main - 280

Needle - Middle (stock)

Pilots - 25 (stock)

Airscrew - 1-1/2 turns from fully seated. (just tell the screw stops when turning them in. Dont crank on it!!!!)

 

Re sync the carbs or you will have crappy bottom end

 

Read up on this site as well

If you have the tors, there is a black box under the tank on the left hand side. Unplug that if you still have them. And unplug all the tors wiring! Tors is very very crappy!!!

 

Go and pick up or get some from a site sponsor's are Main JETS. I had started my collection from 240-350 mains. But that is because I have ported jugs as well. I would look at getting from 250-310 for main jets. That way you will have all the room in the world to jet when you get snow and when you ride in the summer. And start mod'n the bike later down the road. It is very hard to keep from buying parts for banshee. Just pipes and opening up the air box will really wake up the bike along with +4 timing.
