Jetting with new exhaust

[boise_banshee]

Just installed a fmf sst exhaust and powercore 2 kit, also boyesen reed valves. Only mods so far.

 

I live in boise, Idaho elevation is 2800ft, its 30 degrees out, trying to get a ball park for these pipes with my set up.

 

Runs super choppy right now at idle but blasts once 1/2 way through the throtle.

 

Got a jet kit on the way and I am reading as much as I can on here in the mean time.....any help would be greatly appriciated.

what is your filter setup? lid and/or snorkel?

[boise_banshee]

Running a foam filter with lid on. may change to k&n with no lid soon.

[AKheathen]

start with 280mains, 27.5 pilot, and stock needle 1 clip rich. (2nd from point) if you try the lit needle, then same setting, or 3rd from point. 1.5 turns on the airscrew to start, then adjust when hot
