My bike (a ‘67 Victor) suddenly quit while I was out for a ride this morning. No bang, just died at 40 mph, after 30 miles on the road, and running very well. Wouldn’t restart.
I suspected the coil, but when I finally got it home (thanks to a friend with a truck) and tested it I got readings of 1.7 ohms and 6,000 ohms in the secondary.
These numbers seem normal. And I just used an in-line spark plug tester and it lights.
Confirmed the point gap at .015, I was going to check the stator but as I’ve got spark... Carb is good and was just cleaned ultrasonically. Would a failed condenser prevent starting?
So any things to look at? I’m can’t really think what else I should check
Thanks
Adam

Wait for it to cool . Singles can get finicky to restart when they're hot .



... stuck valve ...?

Wish it was just that, with which I am very familiar. I added a choke for summer stops.
In this case I was on the road, under power at ~40mph when the bike died, and will not restart.
I have compression, compression release required, tho I’ll check valves tomorrow..

If you've got spark and compression, it should start if you squirt a couple cc's of gas into the spark plug hole, unless the condenser is a dead short to ground (but then you wouldn't have a spark). Of course I assume you have a new spark plug and it is not already fouled. The bike will start with no condenser, but won't rev up and the points will look like St. Elmo's fire if it does start. My second bike ever was a '66 Victor, and what I remember most was - - trying to restart it when it was hot. I never did figure out why, buy always succeeded eventually, so I didn't try to find out. That was a long time ago!

If I recall, the rotor must be timed correctly to get the spark at the right time, so check that the rotor is tight and has not stripped it's key.

Pull the valve adjuster cap off and have a look at the pushrods
Good chance one is not where it is supposed to be.
If the exhaust does not open you will have lots of compression.

As previously mentioned a bit of whiff ( I use carb cleaner it is easier on the engine ) down the plug hole, just a short shot.
If it does not go bang then check the points cam has not shifted on the taper.

If it does go bang then repeat the process except spary the goo in the carb throat.
If it goes bang again your carb is the problem
If it don't go bang then the valve / valve timing is the problem.

What could cause a good running bike to shut off?

No fuel. Empty tank, blockage in the peacock, stuck float.

No compression. Major foul up, stuck valve, broke ring, holed piston.

No spark. BROKEN OR LOOSE WIRE!! Bad coil, switch, or voltage.

I,m looking at the third possibilty

I’ve checked flow from the petcock, at the petcock outlet and a the carb bowl drain. Steady flow ensues.
I had the valve caps and pushrod inspection cover off and the pushrods are seated and the valves are opening (and closing) in the correct order.
I’ll try Trevor’s suggestion this coming weekend and add a drop of fuel through the spark plug hole to see if it catches.
If it doesn’t, I guess I’ll order a replacement/spare coil. They’re cheap enough.

It’s ET so there is no switch or battery, only 3 wires (the other 2 are for lighting) from the stator to points and coil and ground. All tested ok with a multimeter.

Thanks to all
Adam

Does the Victor use a dowel ... or rotor key
To locate the rotor ?

The stator is keyed. I took the primary cover off in order to really grab on to the stator and make sure it’s on tight and didn’t slip or come loose from its center.
Stator is tight and Timing is still right on.

continuity , from coil ... lost when the Points open ?

The points cavity wiring space is a bit cramped .
The coil wire connection to the points/condenser stud can
Twist or twist-off a strand of wire and ground out . ?
This would cause a short if this was a battery ignition.
But with the ET ignition
it would just prevent the points from breaking the shunt-circuit ..?
