Singles / Re: B31 oil leak
« on: 30 June, 2022, 20:15:00 »
You are correct there is no oil seal on the engine, the breathing should be done via the pipe on the bottom of the timing cover. There is a metal disc in the unit coming out of the cover. If there is no pipe then maybe someone has fitted a cover from an M20.

Twins / Re: Speedo cable for RGS Recommendations?

There really shouldn't be oil dripping from the cable, oil can wind it's way up the cable and into the speedo head and stop it working. It would seem that the bush in the speedo drive is worn and allowing gearbox oil to leak out onto the cable.

Singles / Re: B31 (1954) - how to fit side stand?
« on: 15 June, 2022, 19:11:58 »
If you were to fit the centre stand the wrong way round you would be unable to fit the spring as the peg would now be on the wrong side.

It sounds as if the rubber of the chain tensioner has broken away. You then get metal to metal contact which will not go away with the clutch disengaged.

Singles / Re: B31 - won't idle when cold
« on: 12 June, 2022, 09:43:42 »
My B33 and M33 certainly will not idle from cold. I start the bikes and ride off, once some heat gets into the cast iron of the barrel and head it will idle, usually within a couple of hundred yards.

I think the return pipe comes up inside the filter. A spacer in the bottom would need to be doughnut shaped, that is why I suggested a spacer on the top.

Oil returns in the centre of the filter. If you were to make a spacer I think you would need to make one a bit like a mushroom. A stem to fit down the centre of the filter so that it will not fall off then fit the spring loaded button thing on top.

The top of the filter is 1 inch down from the top of the oil tank neck. The spring load button thing is 1 1/2 inch long and when on the filter the top of the button is 3/8 inch below top of neck. The button thing does come off easily but it come close to the bottom of the neck so cannot fall into the tank. I hope this is of some help.

I'll go into the garage tomorrow and measure it for you.

My 1949 M33 has the slightly later gearbox then your B31 but I have fitted a 4 spring clutch to it I bought from Kidderminster. The problem with fitting the later box is that the mounting lug is I believe wider so you need to trim it to fit the early B31. I read about this somewhere about how much to take of. I can't remember where unfortunately.

Twins / Re: Cracked cylinder liners
« on: 08 June, 2022, 22:42:26 »
I can't for bikes but years ago my father in laws Morris Traveller threw a rod and took a chunk out of the skirt on number three cylinder. I just put a chamfer around the broken area. It run for year like it. Also when I was involved with a RT bus the same thing happened on the engine. A good chamfer enabled it to run for a few more years until we sourced another engine.

On my M33 the spring loaded filter top is quite firmly attached to the filter. you have to push on the cap to lock it.

I believe that the A65 around 64 -65 had bigger valves for one year, it seems that it wasn't very successful and they reverted back to the previous size. I'd will have to try and find where I saw the information.

The early A10 badge is a metal BSA with a wing gold in colour.
