Ok I know this question gets asked a million times but I was wondering where to start on my jetting I have fmf exhaust 32:1 premix andvanced timing v4 reeds 60 over Vito's super stock piston open air box located in nj
in these temps and your elevation, i'd start around a 310/320 and work down
in warmer months you'll prolly end up around 270-290
but start rich and work down to be safe in these temps.
