Identify these bikes! / Re: L'il Villiers

From what you have given me I think very early postwar. It all seems to point that way. As it happens my Excelsior equivalent is a 1940 model so more or less last gasp prewar and very handy for comparison.
Supposedly Villiers did their final 9D upgrade in 1939 but when in 1939? War was declared in September which is also around the time the whole motorcycle industry including Villiers started announcing next years ranges and anything new. I'm still ploughing through 'MotorCycling" at the State Library and haven't got to 1939 so haven't an exact date yet but will in due course. 1940 was going to be a big year for Villiers. Lots of changes and upgrades that came and went between the declaration of war in September and the halt of civilian production in April 1940. Hopefully the State Library will clarify a lot of questions.
My Excelsior has the AAA prefix only and the number, 18330 is in the expected prewar position. The frame number is 1073 with the correct prefix for a 1940 Model 0. It is on a flat boss on the left side of the steering head lug just above the down tube. The frame number is always on the special raised boss provided for it. Your auctioneer isn't trying too hard if he can't find it.
The first batch of postwar Excelsior to arrive in Victoria all have AAA****A engine numbering system in the vertical style. We know this from the AOMC engine number cards as they all contain the date of first registration which leads me to believe its the original fitment with the auction bike.
We also know from past investigation that a Waratah /Excelsior was not quite the same as the current model Excelsior . All Excelsior but not quite identical, usually with the odd part from previous years models. I think that is what has happened here, in an effort to start selling bikes again in the early days of peace Excelsior cleaned out their stores and made up a batch of Waratah from what they could find. As I mentioned before, that bike has a prewar frame and forks that were used on other model Excelsior. The frame number would reveal a lot. I think it's genuine and very early postwar.

Have been in and out so trying to keep up to date with everything....

Yesterday I spent an inordinate amount of time looking for anything that was 7/16" in diameter in order to make up a new breather insert for the timing case, then eventually I found the remains of the stud I used to make the grub screws for the holes in the cases. I thought I'd thrown it away, which is not like me, but eventually it turned up in the Imperial taps & dies toolbox!

I also found the remnants of the tubing I'd used for the push rods, which is 7/16s as well.

I first tried making fitting from the old push rod tube


But the die got away from me somewhat.... :(

So I tried to make something up from the stud.
But I only got so far...


Unfortunately when I tried to drill the hole down the axis of the stud... The bloody drill bit snapped.


So that was plan B down the shitter.

I had another, more successful go at Plan A, with the other bit of tube from the new push rods


But to get to that stage... I had to get the grub screw out first.

Which was a struggle.

I used an impact driver, heat, a dugga dugga, more heat, the impact driver again, more heat, hammering one end of the slot with a screwdriver, more heat, more dugga dugga...

And EVENTUALLY the !"£%^% came loose!

I mildly mullered the thing, so today I started by cleaning up the grub screw in case I need it again, and cutting the slot a lot deeper!


Some more parts also arrived today.

These are extended adjuster screws for the Concentric.


Compare to the old ones


And fitted to the carb


The main benefit, as far as I'm concerned, is that I can tweak the screws without a screwdriver.... :D

I then rummaged through the filthy bag of filthy hoses again and found something vaguely appropriate for the breather and fitted it.


It vents directly into the catch tank


Hopefully that will reduce the amount of oil being blown out of the push rod tubes, and if so, I'll have a go at sealing them with RTV, but I'm hoping to have time for a quick test ride tomorrow....

Maybe.

Because the other thing I did tonight was whip the Pilgrim pump off the timing case. Still not sure why I did that... But hopefully it was worth it.

Well, in wanted to see if the continued oil weeps that end up dripping off the bottom of the pump were actually coming from the pump.


This is a "spare" I have, which I got out to peruse and ruminate on, because I wasn't sure exactly which bolts were holding the pump on.


This is the driven side.


The pump is only held on by 2 bolts.

So I undid and drained all the hoses, and removed the fitted pump
The gasket came off easily with a sharp knife, it was shagged.


This is where the pump fits:
Top to bottom: fastening hole, drive aperture, fastening hole, oil feed oil.


(No wonder they leak...)

I was actually pressed for time, so I hurriedly made up a new paper gasket using the original as a pattern


Then got the 3bond out again and applied it "sparingly"


Placed the gasket


More 3bond on the outer face of the gasket, then refitted the pump, remembering, thankfully, to replace the drive thimble first!


The primary and secondary pumps are both held on by the 2 bolts... But nothing is holding them together. Well, I think there's some silicon sealant or something, but no visible bolts/screws or anything! I also have a nasty feeling that silicon bond might be compromised....


I did the bolts up "finger-tight" to let the silicon 3bond go off with a little bit of expansion, then I'll do them up properly tight tomorrow, and pray that the grey goop didn't get into the feed hole!

Yep, there was the Old Fossils Run at Waterlooville, and another classic meet near Guildford on the same day.

Forget the ISDT, here's the 125 Waratah on the home sporting trial front, prewar.

From the auctioneers: " The engine number is AAA24024A was located running vertically down centre of the gearbox. Will add the photo later.
Frame number is not visible, will send a photo of the steering head casting."

What do you think 33d6? Are we very-late-pre-war, wartime, or very-early-post-war? I don't think I'd argue if someone said "1940", but I don't know the significance of the suffix "A" on the already "AAA" engine number.

The flat-back VEC headlamp (Acme progressed bullet shaped VEC headlamps on at least some 1940 models) and the fact that new Waratahs weren't landed until July 1946 (but which time we might expect post war numbers?)... yes just pre war maybe?

Re the frame number, I told them, "The frame number is usually on the left side of the steering head casting." Anywhere else it might be? A photo would be good.

Cheers

The 8D/9D engine did much better in the ISDT than you think R. The Dutch make Eysink, were the other user besides Excelsior and the record is 1937, three Eysink entered winning two bronze and the other retiring with a frame breakage. 1938 saw one Eysink and the Excelsior entered, both winning bronze. 1939 was the ISDT run on the verge of WWII where the entire British contingent left before the event was over. The Excelsior owner "retired" on the second day but we don't know whether he actually retired or left when told as no one really reported on the activities of private entries. It was all about the official teams. Those representing the country, the Army teams, Club teams and the like, private entries rarely got mentioned much and rarely photographed. Usually they just turn up as background in the odd photo. No Eysink were entered for 1939. Finally Eysink had three 9D  powered entries in the first postwar ISDT and won a Gold and two Silvers.
Not a bad effort all up for a 125cc Villiers.

I look forward to any reply from the auctioneer. It'll make interesting reading.

However, the 1939 Excelsior brochure shows high level exhausts as std fittings on the 125cc Universal, 
so you'd expect the Waratah here to be the same ...

I have a pretty poor illustration of a 125cc (8D presumably) Waratah in December 1937 and it certainly has high level pipes like the GO Universal Excelsior.

I've emailed the auctioneer re engine/frame numbers for the Waratah.

It had nothing to do with competition,

It never actually occurred to me they might be used for competition.
If someone won a medal in the ISDT, then I'm in awe !!

I think the high pipes with Excelsior was just a matter of making your 9D powered bike look a little different from the rest. So many makers took up the 9D they all tended to look the same so a maker had to do something to stand out. It had nothing to do with competition, Excelsior had the Manxman for that.
 Wolf also fitted high pipes but Wolf never had the same exposure as did Excelsior.
So far I can list Coventry Eagle, Montgomery, Wolf, Excelsior, Carlton, Chell and of course  Francis Barnett and James as making 9D powered bikes without listing the Continental users.

Nevertheless, a private entry 9D powered Excelsior did earn a bronze medal in the 1938 ISDT so they were willing beastie if you pushed.

Aye. High pipes was a prewar thing.

If the model you wanted didn't come with them, you could probably order them anyway.
Road trials, of the long distance type were very popular.
And having 'the look" sold very well.
Just watch out for the leg burning potential !
