New BSA A10 Owner

Hi,
The videos are not great quality 
I hope Trevor watches them and replies as he is more knowledgable than me

I can see the rear stays and brackets are not RGS
I could not see the front wheel size? is it 21inch ? if its 19inch then the front mudguard is wrong
The front wheels size is usually 19in.
The front  hub looks grey rather than silver painted
The camera was out of focus when pointed to the gearbox so the letter shape and style could be looked at
The gear change shaft is the standard one not the extended for a retaining clip RRT2 one
No look at the frame number  ??

I could not see the seat centre supports, (often missing leading to seat and mudguard issues)
Wrong speedo / rev mounts
Rocker oil pipe routing is "unusual"

I dont know what to say about the frame "mod"

Definitely not concours.
Front guard is wrong, it has no beading on the leading edge.
As John says, the rocker feed is unusual, not right at all.
The top yoke is from a plunger or rigid model, completely wrong.
The sleeve nut behind the horn is not fitted.
The frame has pump brackets which it should not.
The centre stand shouldn't have the extension arm unless the machine has twin pipes.
The tank top decal was not an RGS item.
The instrument brackets are short, should be long and angled.
There appears to be rust coming through the tank bottom.
The steering damper knob retaining plate is wrong, it may just be the angle but the shape seems not quite right.
The ammeter is wrong.
All of these as well as the bits previously posted as wrong. This is from looking at a video and not in person!
I wouldn't be happy with the frame mod, either.
The speedo is 140 MPH, as fitted to US models. I can't really criticise that as mine has the same.
The 190mm hub should be hammertone silver, I believe.
All in all the bike looks OK but the defects should knock quite a bit off the price and I would definitely have a real good look at the frame.
The front guard on the first bike is wrong, also. It shouldn't have beading on the back end. Sorry GT6.

Hi guys, from that walk a round, it looks to me to be an A10 or gold star frame converted so as to be able to be interchangeable from single gold star or A10 engine. The kink in the frame looks a bit d.i.y. And I don't believe that the R.G.Star had the tyre pump facility, cheers

Ref the Bob Currie book, it's currently in print and for sale, so there is (very probably) some strict copyright.

We have to differentiate bewteen scanning old manuals\magazines\books from the 50's etc and current publications,
= some posted scans will be removed.

Thanks a lot Gentlemen!
The advice is invaluable. I will take my time in deciding which RGS to buy. Incidentally there is another RGS that has come up for sale in California. Will post pics when I get them.

Hi All,

Thanks Trev, I had hoped you would reply,
I must do some more research 
Whats the difference on the yokes?

Klaus,
THe RGS engines came from the "normal" Super Rocket production line, so are not uniquely numbered
The only way to know which model the engine came from is a search of the factory records
You see quite a few cylinder heads advertised as RGS where the last two digits of 1549 are overstamped 1571,
This signifies the "Big Valve" head, these were also fitted to Super Rockets

Here are it's pictures. Ain't she pretty!!!

[a10 gf]

Excellent +++

[trevinoz]

John, the yokes are different shapes for a start with a few details also different.
I will photograph both and post later.
As to the heads, both 1549 & 1571 are big valve heads. I cannot for the life of me see any difference in them. The only explanation that I can think of is that the 1571 was used with the 1-3/16" carby or they had a slightly modified inlet tract which I read somewhere years ago but can't remember where.

Goldy tank also (GP carb dent) not RGS

[trevinoz]

Hi John,
Pictures of the top yokes for plunger and RGS.
Plunger top yoke from 1953 looked the same as the swinging arm version but has a different part number and my expert friend says that the angle is different.
Trevor.
