Identify these bikes! / Re: Barr and Stroud mystery bike
« on: April 13, 2018, 08:35:03 AM »
Having explored the innards of one of JFergs B&S engines in company with him I can't really see how one could say they were difficult to get the port timing right but I'd certainly agree that just because you know how a cam operates to push open an inlet or exhaust valve doesn't mean you totally and fully understand the sleeve valve at first glance. It does require some degree of thought and some people find thinking very tricky.
I also think you can't really compare a double sleeve valve engine like the Knight to a single sleeve valve engine like the B&S. In one move the single sleeve valve reduces engine complexity by half thus markedly reducing any tendency for the famed sleeve valve smoking and excessive oil use. You have to remember the great majority if not all smoking sleeve valve stories all relate to double sleeve valve engines.  B&S motorcycle engines have exactly the same total loss oiling system as every other motorcycle engine of their day and use no more nor no less oil than any other and smoke no more nor no less than any other.

And yes, R, two stroke oil is very good in sleeve valves as JFerg will confirm. His is well pleased with it.

It's a pity the sleeve valve engine didn't receive a fraction of the effort and development as the 'umble poppet valve but it didn't and we now have a fascinating side story of what could have happened but didn't. It keeps us entertained doesn't it.

The original 7 Zetland Rd house is long gone unfortunately. For a moment I was hoping it could be our house as Iíve been told our garage housed a Minerva during WWll and as a boy a local VVMCC member remembered the owner carefully cranking it over to keep the sleeves free. It wasnít much of a leap to hope he was the local sleeve valve nut and he started out building his own cycle car. No such luck though.
I have found out the Davies were the local estate agents. Iíll keep digging.

Most Barr & Stroud engines came 'loose' to Australia Leon. Only a few appeared here already in a bike. I suspect JFerg could pretty well nail down this one as they say it's the 1000cc vee twin.

Mont Albert is very much my neighbourhood. I'll have to see if I can find out more about J J Davies from the local hysterical society.

Where did you get the photo? I presume you found it through Trove? The exact date and page number would be useful. I can then tackle the State Library direct for a decent quality copy.The Library is so understaffed for best results you need to hold them by the hand all the way through. They're willing but drowning.

And we have yet to hear from 'barramundi'. We haven't had an answer to the original question yet. Do you think we've scared him off? The poor bloke probably wonders what sort of nutters has he stirred up.

Hi mini-me,
There are possibly more surviving V series Matchless out here than in the UK. I've known of several V2. I owned a later V3 myself some thirty years ago and an example of the original Model V did surface locally but disappeared again after the owner received a nasty head injury. They all suffer from the same problem of needing an owner with a decent machine shop to sort them out. Like all Matchless of the period they're under engineered and with poor lubrication. Their engines don't wear well.
Mostly we make our own bits as we are well used to non-existent after sale service from English firms. Of course two world wars and the Great Depression didn't help. Doug just has to find the right local firm but as he signs himself 'barrramundi' I don't think he lives in the engineering south. He might just have to search a little harder.
I look forward to his comments on the roller bearing rocker gear.
As I said earlier and Chater Lea 25 has reinforced, refurbishing roller bearing cam followers is not that hard.

Can you explain a little more? Do want to source them because they are missing or worn out? Lubrication on thť V2 was rather basic and the cam followers seize up and wear out rather quickly. Rebuilding them isnít that hard.

Yes, could very well be Levis. One of the Levis two-strokes models  in the late 20's did use that double tube frame arrangement, and those Druid forks and that Sturmey Archer FW gearbox plus the frame number is on the money also. It's a lead well worth chasing up.

Once again, the VMCC is your best bet for info. I can't remember offhand exactly what they have but there was a very active Levis Marque Specialist back in the 1970's-80's who gathered up much of the remaining Levis factory records so if it is a Levis it's quite possible they can identify your bike precisely.

Can I ask about the rear wheel? I can't see it very well but I think BSA?

Hi Barny,
You're not going to get far until you have an accurate frame number so start there. Getting it on the road legally and dating it accurately revolves around the frame number so that comes first. When you have the correct frame number the obvious place to go is the Vintage Motor Cycle Club. They have marque specialists who have a good knowledge of all the minute trivia necessary to tell you what you have. You must be a member of the VMCC to access these marque specialists. They cannot and will not give out the private details of their members to anyone who asks. You must be a fellow member. You can then approach the Sun marque specialist for advice. As I said earlier, my first impression says it is a Sun frame. Remember, in the end it is the date of the frame that dates the whole bike so it is the most important bit to get right.

I'm sure John H told you your engine is also a bitza  with a Super Sport top end on a 1E crankcase. The 1E was the cooking version of the Super Sport with fixed head and cast iron piston. Both the 1E and Super Sport more or less share the same bottom half so popping a Super Sport top end on a 1E is no big deal. It just leaves you with a glaringly wrong engine number when you say it's a Super Sport engine even though it has all the right parts. With that engine number you have an improved 1E, not a Super Sport.

Don't be downhearted, you have the foundations of a happy little fun bike. Accurate dating of the frame may place you just within the vintage period which expands the horizons a bit. Both the 1E and 196 Super Sport were introduced in 1929 and that Sturmey Archer FW gear box dates from 1925-30, so you may have yourself a nice little vintage bitsa and people will be happy to see it on the road.

Whoops! Blew the bottom picture up a lot more to see itís not a carb from a 6E but a later Villiers carb still. Itíll work fairly well but original even better.

You're right Barny. 1930-ish Excelsior it ain't. I have the 1930-ish Excelsior yours is meant to be and the only thing in common between the two bikes is they both have two wheels and an Excelsior tank transfer. Sun used that style of double top tube frame frame and also sold frame fittings to other manufacturers so it's not at all that unusual but forget 1930-ish Excelsior.
I think your frame number 197SS is a recent stamping with someone playing games. I'd have a good hunt around for the original number. You'll have fun trying to get it past DVLA as is.
Can you give the engine number? We can then identify it for you. Villiers made a 196cc Super Sport engine which has a different bore and stroke to their later 197cc engines and I can see your engine has an incomplete carb from a later 197cc 6E fitted plus it appears to have electrics from a 6E fitted also.
To my mind you have a complete bitza made by someone who had a fair idea of what they wanted but didn't quite know enough or have skill enough to do it properly. It won't take much to get it well sorted and then you will have a fun riding bike that you can steadily work on to get really schmicko.
Looking forward to more info.

Now you understand my enthusiasm for wrapping it all up in a bed sheet before removal. No drama. No bits flying about. No waiting for the left ear to be plucked off as a spring whistles past a bit close.

It makes you wonder if the designer ever thought how his design could be put together or pulled apart again for maintenance or just left it to the bods on the shop floor to cobble up something. I suspect the latter.

I used an old bed sheet when disassembling my effort. I wrapped it around the whole shebang several times until it looked like a mummy and then gently tapped away. It caught everything comfortably. Nothing shot off anywhere.

For reassembly I made the clamp as shown in the earlier photo. I first assembled everything on the bearer rod which lined everything up. Then clamped it all up tight with the bearer rod still in place. The it was just a matter of removing the bearer rod, popping the unit in the frame and slipping the bearer rod back in. As everything was new, straight and well greased it was surprisingly easy.

The only fussy bit was not scratching the new paint on the spring covers. You can see the thin card protectors between the clamp and the covers..

I think you've done the hard bit Ian. It's all cruising from now on.

Are the sliders bushed or being alloy do they run direct on the central rod? I'm trying to attach a photo of the last plunger rear suspension I did. It shows both the clamp I used to fit the refurbished units plus the extra grease nipple I installed on the top.

Whilst serving in WWI Norm Maplestone met and married the daughter of FE Baker, the manufacturer of Precision engines pre WWI, the Beardmore Precision afterwards and finally the Villiers powered Baker.
Mr Maplestone came home with new wife plus a couple of Barr & Stroud sleeve valve engines. JFerg can give chapter and verse on this and I believe has even been bailed up by a Maplestone descendant trying to do a family history.
It's all go in the early motorcycle world isn't it. Far more fun than just riding a clean, reliable and utterly boring modern bike that you can only polish.

You're right Doan. It isn't in the right section of this forum. I for one would hate to see us swamped with For Sale notices so would be grateful if you removed yours. As entry to the forum is through the Vintage Bike site you passed by the Bike For Sale bit to get here. Just pop back a step or two. You'll see it there.
Best of luck with your sale.
