Bonhams sold a 1954 Sun with such an engine prefix.
Assuming it still had the original engine...

Engine look familiar ?

Indeed, a very distinctive model, a 500cc single.
And with a 4 valve head, which made it extremely sporty and expensive for its day.



This picture is actually of a 350cc, presumably from 1925, does anyone know how to tell them apart ?

A sunlit pic of the timing side would probably assist greatly in getting it id-ed.

Put it in with the long-term-projects side of the garage, and do a bit to it now and then.
After a while, you won't remember the cost, and it will start to make progress.....

British Bikes / Re: Starting a BS SS100 replica build - help!

I waz imprezzed when someone came on his harley to visit my neighbor  - all kitted out with with springer forks (not unlike Castles), BS type exhaust system AND a timing cover with forward extension, very much like the JAP.
I didn't have a camera with me, but at first glance it looked like a JAP engined BS...

Not having drawings doesn't stop that guy in Canada that made the V4 Ajay replica !
He just did it all by eye from photos, and made it work ...

There are lots of folks doing JAP engines, when you count them all up.

Surely there would be less cost just buying one than all the expense of doing it yourself ?
Less fun though, if you have the time  ...

Keep us posted.

If that B&H engine is patented, it should be possible to track down the patent.
Especially if the patent number is available.

ClassicBikersClub has this.

The Grigg side-valve V-twin - August 1923

The August 16, 1923 issue of The Motor Cycle announced that the Grigg Motor & Engineering Company in Winchester Road, Twickenham would be marketing a range of single-cylinder and V-twin engines under the patents of Messrs Bacher and Hellow, who were responsible for B and H engines...

Seems you have to be a member to read more.

Bikes made in 1926 were generally rather obsolete by 1939. !

And there is nothing about your bike photo that suggests it was postwar,
it looks completely prewar.
Tank style suggests more 1930-ish or thereabouts.

Think you are getting very close.
That tank decal looks to be a certainty.



Its almost 100% they would have changed over the years, so its 'only' a matter of finding the right year and model.
Can't say I've even heard of them - but there were myriads of makers back then....

There is some similarity with this swedish rudge example. (looks a little cut down)
https://upload.wikimedia.org/wikipedia/commons/2/29/Rudge_500_cc_TV_1927.jpg
But many differences.

As with this yesterdays example
http://www.yesterdays.nl/images/Rudge-1927-special-k-1.jpg
Tank is angular, but a different shape.
(And those tyres look oversize ?)

Rudges in the 1930s had the new bulbous saddle tank/ look.

That whole outfit has a european look to it....
Even the stays on the rear mudguard.

Nope, not Norton.

And with the chair on the right, and that central pillar mounted headlamp, its likely going to be something european (?).
Tank badge scheme is not familiar to me either.

Someone will know....

With Brexit, maybe it could be "Ever Imperial" ?

Yes I'd go along with that.
Explains why the tank logo didn't really match, dimple in the muffler etc..

P.S. Someone on another forum  has just described a carb that was badly worn, and required the slide to be resleeved to bring back a reliable and adjustable idle.
It also would keep running with the slide down quite low - but required much choke when cold.
Curious and curiouser ?

Are you doubly sure the slide is not hanging on the throttle cable ?
It would be very strange indeed if the slide can be fully bottomed out and the engine will keep running.
If you wind the slide stop screw right out, can you hear the click as the slide hits rock bottom.

Does the idle mixture screw alter the idle when you adjust it in and out ?

Amals are rather prone to the little fuel and air passages becoming corroded or gunged up.
It can take a lot of cleaning to get them all clear.
In the meantime, if the carb has been adjusted to idle on the needlejet, it might do like you say.
But dropping the slide right down should kill it stone dead.

What happens if you turn off the fuel, and let it idle and run the carb dry.

If you haven't checked it out yet then, 1st thing to look at is that an automatic advance unit
(if fitted ?) is actually retarding at idle.
