So I’m a complete 2t newb coming from 250/450 efi bikes I don’t know much besides the basics of a carb and I cannot get this thing running right no matter what
It’s running
32:1
vf3 carbon reeds
Full pc exhaust system
420 main
40 pilot
Needles on 4th clip from top
It’s very weak in low rpm then once it’s in band it pulls but stutters
