Im putting a bike together with the following.
Stock carbs with pod filters
cpi inframe small bores.
PD coolhead with 20cc domes
advance timing +4 degrees
Lightened flywheel
Boyesen pro series reeds on stock cages
Elevation 0-700 feet riding, sand dunes, and pavement.
I was thinking of starting at about 310 mains. Anyone have a better suggestion for where to start, what needle clip position to use, and pilot jet/ air screw settings? I usually mess with TM's and pwk's, so I am sure there are a few on here that will have a better idea of where this thing needs to be.
