Choose an aftermarket inlet manifold to fit SUs, Webers and other sidedrafts, as well as alternative manifolds for the stock carburetors.

Contents

Overview

  • Aftermarket manifold finish quality can be really poor so check for flat flanges, port overlap. See Jason's Weber page
  • Weber DCOE type manifolds are used by Dellorto DHLA and Mikuni/Solex PHH series
  • Hitachi sidedrafts can use SU manifolds, but there are two-bolt diagonal pattern and four-bolt pattern
  • Buy a complete kit -- unless you like scrounging for all the little parts
