Twins / Re: A10 rocker cover
« on: 11 February, 2017, 11:50:43 »
Anybody know of a fool proof method of refitting the A10 rocker cover, and keeping the the pushrod location tool in place while doing so?

The best method I found was to use the comb but bend it in an S shape so that it fits flat on the top fin of the head then secure it with some thin mole grips, this holds everything in place and I find its pretty easy now, I hope your using one of my solid copper gasket sets, to stop the leaks.

Thanks Julian, I guess that could be the answer to the problems, hopefully. :)

Twins / Float level on a 930 carburetor
« on: 09 February, 2017, 09:23:51 »
I have a 1963 A65L which is running but I cannot seem to get it to tick over correctly, now I believe someone told me some time back that the float level in the 930 concentric carb is critical so I made up a tube so that I could see what the level was, turned out that the actual level was roughly 1/2" below the joint of the bowl, I think, if my memory serves me right that someone said it should be 1/8" below he joint.
Am I correct in thinking that the later level should be correct and that I should try to adjust it to that sort of measurement?

 I have a spare solid copper gasket that came off of a C15, your quite welcome to it for the price of the p+p, the other trick with these is to put a thicker gasket under the barrel, or double up.


Singles / Re: B31 crankshaft/ cushdrive woes
« on: 06 February, 2017, 13:10:53 »
Have been through the old parts books.

The B31 used the same drive side mainshaft from 1946 until 1957 when it changed for the alternator engines.  Part 65 1128 for the shaft and nut 65 2520 until 1955 when it changed number.

So the thread would be 3/4 inch x 20 tpi cycle for both cush drive nuts.

I dont recognise a 22 tpi thread. A cycle thread would be 20 tpi or 26 tpi.

22 tpi is fairly close to a 1 mm pitch metric? And 18 mm is close to 11/16?

Colbrew, Whitworth did a different size on their threads, some of those were 22TPI, most likely that's what you have, if I remember correctly I had to purchase a tap, I think it was for a military M20 axle. HTH

Twins / Re: BSA A10 twin leading shoe brake
« on: 03 February, 2017, 08:57:31 »
I don't know why everyone raves about twin leading shoe brakes, I have found using both this also the single sided brake 8" drum as on the early GF and GS the most efficient ie, better that a TLS, I think a lot of problems with braking are to do with the distortion of the drum when a new rim is fitted, if its not laced properly.
My 2p for what its worth.

Julian. You could be correct with the bike but I think the photo was taken somewhere around 1948-50 judging by the dress, the pirates were a speedway team initially formed at Poole in 1948 and when you think of it, we all rode old bikes then, anyone who had a new bike must have been quite well off.
