Identify these bikes! / Re: Precision Big4 frame ?

I'm working on it.
In the depths of my garage, nothing is readily visible.
Getting it out of there might require an early spring clean !

Yes I saw him in the movies.
I doubt he knows much about CE's though ?

Don't you live just around the corner from the OP ?

How would an Amal off a BSA Bantam go ?

(Did we ask if the original carb came with this project ?)

Can anyone identify this ?

Would this be suitable for a Big4 engine / build ?

Villiers loved those curly-whirly manifolds.
Keep your eyes peeled, this one is about the exact mirror image ?
Good luck.

'The Vintage Motorcyclists' Workshop" by Radco contains a full double page photo

Split across 2 pages it must be noted. The manifold is slap bang in the page join !
All the online scans are awful in the picture dept, they must have scanned a photocopy

I've done some lost wax casting.
Doing a curly plaster central core of the actual gas pathway and coating it with wax to a suitable depth and then coating the whole
shebang in more fireproof plaster is possibly the simplest method ?  You'd have to find a foundry that does this type of casting.
Simpler than it sounds, and cheaper as a one off than making moulds and core moulds.
The cast metal very accurately replicates the finish on the wax - so you could inscribe your image on it !

Or does it have one of those curly-whurly alloy thingies - to the other side ??
That makes it somewhat more  complicated ...

A simple tubular stub - to suit the carb, and a 2 bolt plate welded on would about do it. ?

You might need to carefully consider the angle of the inclined cylinder,
best so that the carb is quite horizontal.
And the weld likely needs to be gas-tight.  Well within the skill set of most welders...

Something like this - a Silent Superb  ?
(it was unclear if this was that actual version).
That manifold doesn't look very complicated ?



Short of endlessly trawling fleabay, or approaching Villiers Services for one, maybe the local fabricator could whip one up ?

I had a manifold made up for an Enfield project. They used a long-necked Amal, which are near impossible to find as the correct one.
Wasn't especially expensive - and I had it done in stainless, so was a real work of art.
A plain steel one would not be beyond most workshops.
And if its all thats stopping you going for a ride. !

Be thankful its not the exhaust thats missing. Now that does look special. !!

Good luck, keep us posted..

Modaks in Melbourne often have useful small stuff like that, at very reasonable prices.
Think he is mail order only these days.
Worth a try ?

Tread carefully here ?

I don't know about the G2 Bullets, but earlier Enfields had those nuts turned down a shade at one end,
so as to go into the CIRCULAR recess in the timing cover. This means hex nuts won't go.
But they may have changed this arrangement for the Bullets ?

Hitchcocks in the UK would have the real deal.

I think 30 and 31 are what is required (no quantities listed, so cannot be sure.)
They look like just plain cycle thread 1/4" nuts.

Luke at Britcycle.com.au had them NOS at $1 each, cad ? plated.
You'd have to chase the washers - stainless ?

Interesting sounding project. ?
Can we see it when done

Oooo Aaaah, a rare bird indeed !
It looks a little incomplete to even contemplate - unless you already have most of one !

That engine must be almost unique in having that head 'sideways' like that ?
Wonder if cooling is better that way ??

Spheerol.

Need to be careful here.
Castrol makes quite a range of Spheerol greases.
Only the OO version is the semi-fluid stuff.
