Recently built a ported rb22 with a 60/110 crank. Currently running a vhsb 34 with power jet and an early nk race exhaust. Jetting is 188 main k21 need on the third clip down on a 266 atomiser and 60 pilot. Power jet is 3/4 of a turn out.
I’m changing the exhaust to a modified jl3 due to the nk’s poor fitment and narrow spread of power. What jetting would people recommend?
