I emailed Alba racing and this is what the said:
Hello,
we do not have a set jetting for the banshee. However, you are pretty close, with the elevation you are at, I would leave the main jet alone, if anything, you can come down to a 290 main, the pilot jet, bring that down to a 25 pilot and the needle, set it at the 4th clip, and the air fuel mixture screw is fine at 1 1/2
