carb jetting sugestions

[bikesndbugs]

Ive got a 85.5x72 engine with an engle 110 cam cw crank single port heads and high rev springs.
currently has a pict 34 but i have a 44 with 28mm venturis.

im wondering what is good jetting for it. anybody run a 44 on a 1600 or 1641

has 50 idle jets and i think 160 mains and it just falls on its face once the mains kick in. Too rich? on the mains

yes it could use dual port heads my dual ports have a crack between the seats and need a rebuild so running single ports for now.

Yeah way too much main jet, should be down to a 120ish unless you're looking at the air correction?

No I'm talking mains that's what I thought. I'll see if I can trade down at my local vw store

Just didn't know how low to go
