British Bikes / Villiers headlamp switch
« on: Today at 07:20:59 AM »
Bit slow here, need something to git thungs movin agin ?

Anyone care to explain the Villiers headlamp switch ?
Waratah/Excelsior 125cc circa 1945

I thought it was a Miller, but new/replacement has a chrome ring around it.
And would be (slightly) too big to fit ??
What retains it - a large wire circlip ?

Villiers Services in the UK is the goto place for Villiers bits.
No idea if they have these particular parts.

1920s BSA's had an I-section backbone, but I'm not sure if it was like that.
Something about Francis Barnett's "built like a bridge" comes to mind also,
with all those bolted joints ?

We are assuming there is nothing untoward going on here,
like a case full of broken teeth jamming up the works. !
Without a full inspection, its a bit of a lottery if this will be good.

Draining the oil and inspecting what comes out is a useful diagnostic tool.
If its nice and clean (and new) it can go back in ?

Can you turn the box over at this point, using the back wheel.

The leading 2 teeth on that quadrant are not ground down at all.
This gives a rather brutal initial engagement, and they can jam.
Ground down a bit, they lead into the others, and swing into action. !

If that were mine, I'd get out the angle grinder with a thin blade,
and shave a bit off the 1st 2 teeth.  Keep the same basic tooth shape,
just shaved a bit, and no sharp edges left.  Easy does it....

So can you now kickstart it OK ?

Is that a fast click click, or slow
The chain contacting something could be a slow click,
but a fast one needs further investigation.
Even the tyre contacting something

Don't recall, is this bike new to you.
Some fettling is to be expected....

P.S That box is later than the CP expected for 1951 ?

If you google this problem, its exceedingly common with Burman boxes. !

The solution is to grind down the 1st tooth on the quadrant, and the 2nd tooth a bit.
Assuming you haven't reversed it from its original fitting.
Which can also be a fix.

Pulling the clutch in when this happens can also sometimes free things off.

Have you tried turning the engine/gearbox over, via the back wheel. ?
And seeing if that makes any difference.

It sounds like the kickstarter is not meshed or located correctly.
Let me find the Ajay booklet to refresh the grey cells, if someone doesn't chime in sooner.

Good call. ?
On a twin, you'd just swap the plug leads over.

But 4 stroke singles don't work like that.

then WIND forward

Aye, if all ye backlashes accumulate, then you may be in no mans land....

Lightly tapping the sprocket onto its taper is highly recommended,
or it may slip or move while you are tightening up the nut.

Good if its all good again but ...

That screw also possibly needs a fibre washer under it/them ?

Since the sprockets look to be in excellent condition, the chain may not be worn ?
Can you just pack the magneto up a bit higher on its platform ?
Or is the platform adjustable even, with slotted holes on one side ??

Usually you'd just reset the timing to suit. ?
Banging the gear onto its taper, and ensure it doesn't shift while doing so, etc.

If the gear shifts on its taper, maybe it needs to be ground in, to get a better grip ?
