With a battery less points system short the wire leading to the points to the engine
With a battery powered points system interrupt the wire between the battery and the coil

Looking at Dartmoor Star's photo. It looks like the footrest bracket is bolted to the brake pedal pivot hole and vice versa.
The footrest brackets use a stud with a hexagonal body allowing them to be mounted in different positions to suit the rider

Is it a dynamo or an alternator version of the B31?

Singles / Re: Centre stand B31 (1952 plunger)

Two points to make here.
1) The centre stand has suffered (and probably the frame as well) from kick starting the bike on the stand
2) forget grovelling at the side of the road fixing a puncture. I have a card with a phone number on it, a nice man in an orange van will come and sort it

BTW pushing a button down until petrol comes out all over the magneto is not a cold start system

It depends what you want from your carb.
If you want originality then its an Amal GP
If you want a carb that carburates cleanly at all throttle openings and engine speeds, will idle and will start easily due to a proper cold start system, then it has to be a Mikuni VM. The Amal GP will do none of the forementioned

B50s don't need an oil pressure switch because they don't have oil pressure. Roller big end, high flow very low pressure

They take the shock when you dump the clutch

The clunk going into first is nowt to do with clutch rubbers
When the gearbox is in neutral the clutch and mainshaft are spinning, the layshaft is stopped. When you pull the clutch in, the mainshaft is still spinning by inertia, clutch drag and bearing drag. Engaging the gear stops the shaft as the dogs engage, the clunk is the backlash in the dogs.
Even if the clutch is not dragging there will be drag between the plates due to movement of air and oil.
Suzuki GT380 triples had a clever little brake in the first gear pinion, when you pressed the lever a little arm contacted a plain portion of the gear stopping it from rotating thus stopping the clunk

Singles / Re: Condenser Missing?
« on: 30 June, 2018, 17:46:29 »
Hi, - interesting. As you know I'm having misfiring problems. My condenser is fitted remotely near the coil. Please explain why it needs to be near the points - I haven't heard this before.

Many thanks,

The condensor does not not need to be near the points, it needs to be electrically connected to the points-coil connection. Fitting the condensor near the coil is better because it is not getting cooked by engine heat

I used the timing cover tapping and made a fitting with a stand pipe on the inside. As you do not have this cover I would try putting a fitting in the tappet inspection cover. No permanent modification to the engine

The later flapper valve breather is better but way from perfect. On my B31 I have fitted the reed valve breather from a Yamaha XS650
