I have a HPC c20xe on 45's, been set up nice but there's an issue.
Light throttle in any gear results in spitting back through the carb, a bit more throttle its fine, on track its fine, full throttle its fine.
Carbs have been rejetted, chokes replaced, rolling road dynoed and set up but low revs on the road in traffic can be a pain. New misabs and the things are not tight the manifold.
I don't know what I'm looking at, and although I have a set of TB's to go on I'd like to retain the carbs if I can.
