The Star and Garter / Re: Light bulbs
« on: 23 February, 2017, 15:18:29 »
In  my opinion I have tried positive  LED headlight bulbs from Dynamo regulator conversions, and consider them to be the best available, the pattern is okay and are much brighter, the ones from PG are not so good.
My tail light unit came from Beck Electronics in Holland, this is not a bulb but a plate which after taking out the bulb socket wire went straight into the hole but I'm not sure if he is still doing them now.

There was usually a lot of play in this type of brake plate and a lot of riders often packed them out to stop the clunking when applying the front brake, if you have one that's tight, I believe its better to leave it tight, I have even seen them with a allen screw tapped into the brake plate lug, hopefully you have not filed off too much.

I see that you say your C15 came from the states, looking at some of their sites, it seems that a lot of US bikes had a 19T sprocket on the gear box, although the standard sprocket was 17T, I have just gone up to a 18T but have not had the chance to try it out yet, I am hoping it will give me a little longer legs, I believe Feck do a 19T but I'll wait and see how the 18 performs.

Have a chat with our National branch secretary, he has one, so he can tell you all about them.

The Star and Garter / Weekend away
« on: 20 February, 2017, 09:05:28 »
Gillian had a few days off at the weekend so she said "lets go down to Wiltshire and see some of the Wilt's branch lads, they are a friendly bunch", I thought, okay, yes, they won't get their blow pipes out this time of the year, so we could be safe. Thursday night we arranged to meet Doug & Sarah Brown for a meal in the evening, which was very nice, the venue was a bit basic but it will be okay when they finish it, tried to arrange a night out with the lively lads from Wiltshire but they turned out to be quite a let down, they were all frightened at the thought of leaving their town and traveling 15miles to meet us except for Clive & Margret Orchard who arranged to meet us at a pub, some 25miles from their home, and Clive was feeling ill at the time, so well done Clive and I hope you are now feeling better but for the other BSA members who let us down I do hope you are feeling guilty now, no names no pack drill, the wrath of Gillian is upon you.
Had a great time down in Wilshire though and I am quite surprised at how many wonderful (historic) things there are in that area to see and great motorcycling roads, so why is it that every year on their camp ride out, they want to go to Calne bike meet? looking at other peoples bikes is okay but not all day, come on Wilt's, get your act together for this year, or would you like me to arrange a ride out for you? ;D

Pre War / Re: Sloper brake problem
« on: 11 February, 2017, 11:54:55 »
I thought there was a dual braking system on the sloper, when the front brake is applied it also operates the rear also.

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
