I am glad we got to talk. I have Leo Vince pipe and the stock carb w/85 main, mixing around 32:1. I've got fuel flow problems, probably a sticky float needle.
I am gonna work on an intake to run another carb, probably a 19mm phbg and bring it out from under the frame. If I do get anxious and run that stock carb, I'll go to an 88 or 90 main and lean out the mix to something like 40:1 or more.
That's such a clean squish band. Did you do it by hand?
