Since you said you could, here gos.

Looking for oem style hand-grips. Where is the best please to get some online?

Compared the some pictures that I've seen my handle bar brake and clutch is different. Mine look like todays style. The pics. show them backwards. Are mine wrong? If so what what I need to replace them?

What is the OEM specs. on the piston and rings? I have a great connection on getting new ones made if I had specs.

Thanks for the reply. But since I'm in the states I can't talk to most folks you mentioned. I'll do an internet search on VINTAGE REBUILDS.

Please check on the OEM specs. on any type of internal engine part. I have a great contact with a major engine parts mfg here in the states.

DIDN'T KNOW YOU WERE IN USA !

RON FARTHING'S THE MAN TO TALK TO:-
www.ronfarthing.co.uk    or:-
e-mail info@ronfarthing.co.uk

THE MARSTON SUNBEAM REGISTER (PRE 1940 SUNBEAMS ONLY) info about club from:-
trevor@daviesnewport.f9.co.uk

They have copies of spec: sheets,spares etc.
and members that have links to the original factory.
(sunbeamland in wolverhampton)

Model 8 std bore is  70 mm , stroke 90mm.
I doubt if your piston is original so your rings will be different to sunbeam's own.

Thanks BEAMA for you help. I should have said I was in the states. My bad. I will probably be asking more question later on. I just pull her out of storage after many years. So loads of dust has built up. I will be spending the next few available days just cleaning her before any work is done.

I finally took the piston out. I have two casting numbers off it. First is HG405AM, also found 3238B. Anyone know who might have made this piston? The Hepolite number I've found doesn't look like it. But I could be wrong.

HI MR TURBO,
YOUR PISTON IS A HEPWORTH AND GRANDAGE,IF THE
BORE IS 70 MM  IT IS PROBABLY THE ORIGINAL.SUNBEAM USED LOCAL COMPANIES FOR THE FEW BOUGHT IN COMPONENTS THEY NEEDED
AND THIS COMPANY WAS LOCAL TO SUNBEAMLAND
WOLVERHAMPTON.

Hi BEAMA.
I think that this will be the first of a long list of questions, although I am not 100% sure whether this is pre-`38 or exactly 1938. My brother wants his pile of rust, oops, I mean Sunbeam, put back together again.
We`ve just shotblasted the frame...which one is the frame number ? There are all sorts of numbers....
Cheers
Jeff

Hi Jeff,
What model is it ? m8, m9 etc. or what is the engine number or capacity. is it a side valve  or ohv.
Sorry are need more info.sunbeam made motorcycles from 1912 untill 1937 then AMC took over production
until 1940 making there own versions ( high cam ) from 1939.So there are a lot of different numbers.
Sunbeam frame numbers are on the front bottom of the headstock and also on the top of the gearbox mount.

Hi Beama.
Sorry for the delay in getting back to you.
We have just brought up the box of engine bits and a couple of boxfuls of rust !!
I am not sure of the cc...but it is ohv and we think 1938.
It hasnt got the large triangular timing chain cover, just pushrods and the elongated oval timing chain cover.
I think that the frame number is 26-1049 and the engine is stamped A 23 E 540.
Does that help ?
Cheers
Jeff

HI JEFF.
A23 ENGINES WERE 1938 250 cc MODEL 14
FRAME NO'S WERE ALSO A23
NOT SURE ABOUT FRAME NO/ 26---
BUT A20 TO 30 SERIES WERE 1938

Hi Beema,

I have a 1929 Marston Sunbeam Model 1 for sale in case you know of anyone interested in purchasing one.

The bike is in v good condition and has been used frequently.  I have not advertised it anywhere else at the moment as I have only just made the decision to part with it.  It is taking up space that I need for other Bikes!

Regards

Helmet

Hi Beama. After all this time... I have another question if I may. You were spot on with the numbers cc date etc. It is an A23 1938 250cc model 14. We are now at the point where we need to source valve springs and I was wondering if you had any suggestions. Thanks, Jeff

hello lads, this is my first attempt at this site... looks very interesting. i am restoring a '36 mod 9, '31 mod 9, and soon starting on a '35 mod 9. i know enough about 'beams to be dangerous, but  i wish to know if anyone knows why in the rockerbox of the mod 9 there is a 3/8" spring and at the end a ball bearing the front is situated with a slotted adjusting screw with an orfice. we know that the small #55 jet floods the gallery with oil that gravitates to the guides, the exess returns down via the tubes onto the cam gear. so why the ballcheck?? there's no pressure?? also, if one fits a Mikuni to a mod 9, it will preform like a stratovarius!.

HI LEON,
SUNBEAMS RUN AT UP TO 40 PSI ON THE ROCKER FEED. DEPENDING ON THE SELECTED POSITION ON THE METERING VALVE.THE BALL IS TO  HAS TWO FUNCTIONS, ONE, TO STOP THE OIL RUNNING BACK DOWN THE PIPE AND KEEP UP THE PRESSURE THUS GIVING FEED FROM START UP AND TWO, TO KEEP OIL IN THE ROCKER OIL CHAMBER. WELL THATS THE THEORY ANYWAY.
NICE TO KNOW YOU ARE STILL INTO SUNBEAMS, I USED TO SPEAK  WITH YOU SOME 6-7 YEARS AGO !
MIKUNI ON A SUNBEAM !  COME ON LEON. MY 90 IS QUICKER THAN IT'S BRAKES ON ITS AMAL.

Hello Beama I asked you before about my model 5 1930 and you tipped me about trevor davies who as you said had a register of pre 38 sunbeamers.
But I already tried to contact him before in may I think and tried again last week but again no response so that's why I asked you again about his e-mail
Did you have any contact lately with him?
I am just curious about the number of bikes of my type that are left

SOMEONE ASKED ME THE SIZES FOR A MARSTON SUNBEAM MAGNETO  SPROCKET EXTRACTOR. CANT REMEMBER WHO ASKED BUT BASICALLY YOU NEED A 5/8" DIA, 20 TPI (WHIT, 55 DEGREE ) BOLT ABOUT 1" LONG UNDER THE HEAD. WITH A 3/8" (HIGH TENSILE PREFERABLY) BOLT WITH ABOUT   2" THREAD LENGTH ( FINE THREAD, BSF OR UNF ) THRO' THE CENTRE. REMOVE THE CAP ON THE TIMING CASE. USE A BOX SPANNER TO UNDO THE SPROCKET NUT. SCREW IN THE ABOVE EXTRACTOR (NO NEED TO TIGHTEN), SCREW DOWN THE 3/8" BOLT HARD, IF I DOESN'T MOVE TAP THE BOLT HEAD. DONT FORGET IF YOU REMOVE THE MAG, THE SPROCKET WILL DROP DOWN THE CASE UNLESS YOU PUT A BAR ETC THRO' THE CENTRE HOLE.
DONT FORGET IF YOU DO RELEASE THE SPROCKET YOU WILL IMMEDIATLY LOSE YOUR TIMING SO MAKE SURE YOU KNOW WHAT IT IS !!!
