I am currently helping a friend with work on his Dominator, and I suspect that the head steady of his bike is not original, or has been modified at some time in the past by a prev. owner.

I would be greatful if any of you can post a pic of the original head steady setup for a Dominator.

A clue as to what year and variety this might be could be helpful,
'dominator's come in at least 4 or 5 flavours. ?

We assume its going to be a featherbed, wideline or slimline though ?
(and it could be a rigid, a plunger or swingarm variety also,
all of which had their own versions of headsteady).

I'd describe most of the headsteadies of these as looking a bit homemade,
so bear this in mind....

I forgot to mention that it's a featherbed wideline frame, mid 1950's,

This is the headsteady for a 54 88.

It has rather a small hole to attach to the head, so I'm not sure if this is
genuine or a replacement/replica - it needs a larger ole to work - or there may be more to it ?

The double ended stud going into the later aluminum heads is 3/8 whitworth, head steady sits on the upper end of the stud and is 3/8 CEI.
It is entirely possible very earliest stud is different size upper end.

All the iron heads I've seen have the stud in 3/8" ( BSC both ends), which is what a 54 dommie would have had,
so I don't know why this example has a smaller hole.
I've looked to see if it had been welded up, but can't see any sign of this.

Maybe it was run without the engine being bolted down
(I've heard this can make for a less vibey ride)( ?)

btw, and it may be all semantics, but CEI was obsolete before any dommies were ever built,
BSC was then the name of the game (British Standard Cycle)(threads),
as was British Standard Whitworth = BSW, British Standard Fine = BSF
and British Standard Pipe = BSP
Along with other assorted threads, which weren't quite British Standards (!!)(?)
BA and 14mm spark plug included...
