after attempting several lost wax (pla) castings, i gave up and made a traditional split pattern set.
basically. a manifold that is canted off at 30 (60?)degrees to the engines centre line, with a 26mm bore, to suit 28mm EFI throttle bodies (such as the R15 or the ecotrons) that will fit all honda cub based (clone) engines. lifan, ducar etc.
it was for turbocharging and sent everything off nicely to stuff in an intercooler..
.
has bosses that can be machined out for a MAP and an inject
