Mystery manifold

Jeandr · Nov 2, 2015

My friend has this manifold and he doesn't know what it goes on! It looks like a very normal Triumph Tiger manifold, but it doesn't fit any of the heads he has. All the head studs are 2¾" center to center but the manifold is 3" center to center. Anyone knows what bike this manifold fits on?

Early 500/600 Dominator twin with vertical screw holes rather than the latter down draught head with horizontal screw threads :?:

If it's Triumph, it's an early iron head pre-unit big twin.

Unit Triumph manifolds fit my 1955 iron headed T110.

Unit Triumph manifolds fit my 1955 iron headed T110.

It is 3" center to center, my friend tried it on iron and alloy heads, fits neither. I looked at pictures of early Dominators and also in the Dominator parts manuals and it looks very similar. I will ask on the "other Norton" forums maybe someone can confirm the stud spacing on the Norton heads.

Early dommies were only 2 1/4" c-to-c in the manifold ports.

Your manifold is much wider...

Enfields and Matchies also had 2-1 manifolds ?
