I suspect the nearest you will get is the Smith's 8 day chronometric clock. A fine match for the chronometric speedometer and handy for these longer rides...

Twins / A7 ST plunger 1952 - Clock
« Last post by ANNIS on Today at 11:21:56 »
Trying to find a competition clock to mount alongside the speedo. This to match the setup on the Maudes trophy winning MOL303. I have checked with the National motorcycle museum who has MOL303, but there is no identifying names or numbers on their clock, so I'm struggling.

The clock is black surround and slightly smaller than the speedo, has a 12 hour dial with a reset/timer needle.
Any ideas or suggestions please?

Singles / Re: B44, Bigend, Piston. Bad vibration.

I have stripped the engine.
I dont think a new bigend was really needed. There is JUST perceptable movement.
Now I have it stripped, I will fit a new alpha bearing.
I suppose the whole job was a waste of time and money, but I still want to get rid of the vibration.
I might try making a weight, 58% of the rod and piston (is this correct? ) Then drilling the flywheels as needed.

answering my own question!
I checked again.
Gripping the piston with both hands, push up and down, moving around and sideways.
Finally found a point where a very small amount of play was felt. Enough to hear a small click.
Im guessing that that is the answer?? ANY play is not acceptable??

Suggestions for a good supplier for replacement bearing please.

I dont think you would struggle to sell it on if you put an ad on here, british bikes seem to be going mad at the moment!

The Star and Garter / Shooting Star
« Last post by A10 JWO on 15 October, 2017, 15:05:15 »
About ten years ago I became aware of a nice shooting star in one of my neighbours garages. There are enough spares including a rebuilt engine and gearbox to build a second bike. He died a couple of years ago and his wife is now considering selling as a job lot. I may be the point of contact one day in the future when this lot is advertised. I have sold quite a few bikes on ebay and other sites, but this is quite a big parcel. What would be the best way to dispose of this lot. It is in Essex.

Twins / Re: A65 Fitting a oil pressure gauge

Put a loop on the capilliary pipe so that there's no tension on it.
Vibration is the enemy.

Should you intend to use the pressure gauge as an instrument whilst bike being ridden rather than as a workshop diagnostic tool you may wish to consider how to isolate the copper capillary from engine vibration and possible fracture.

A fractured pipe, which is situated between the pump and the crankshaft, would likely lead to a catastrophic engine lubrication failure.

Service sheet below from BSA gives a pressure figure.

Pre War / Re: Sloper wiring info advice please
« Last post by tonyairconchap on 15 October, 2017, 09:27:31 »
Hi Bevan, thanks for the offer, i have a wiring diagram but it does not give the length of the cables under the tank panel.
should they be long enough to remove the panel?
How long shoud the inspection lamp wiring be?
To remove the tank i will need to disconnect the cables, could i install a connector block to make it easier....anyone else done this?
kind regards
tony
