Richard,

Whew! Put me down as another soul who made it to the end of gigantapost. The main thing I got from it is  what I think you intended, that being, you've got some really unusual bikes there that we need to see.

Good Morning,I had a good chuckle with the replies from richard and dutch [did I get that right?]. Very funny and yes I do like unusual bikes and I quess I am also an unusual guy. Also, my high school grammar teacher would have given me an F for that long run on post. Anyways, I think I figured out how to send pictures so will do so later today. I do have one question though. Does anybody know if the separate early A-7 inlet manifold will mate up to the dual port A-10 head? Is the center to center width of the ports the same? Billerick

Richard,

Best chance for an answer to that manifold question would be to separate it to its own tech topic. That way it can get the attention of someone with that knowledge who is not following the current thread.

 Lucky it wasn't deep so dig it out.
 Note that I said "  It sounds like the one I erroneously had on mine..." not to imply that's what yours is   , and I'd be surprised if you haven't been down that Avenue....

 Mine is of ferrous(or should that be 'ferric'?) metal and no backing plate or splines as I used mine for those. Here's some pics, hope is of some help;

This breakdrum is from a B44 but it is usable also on A10 SA frames. I have such a drum fit on my A10. As I remember there had to be used an other bearing sleve, the same as B44.

cheers Klaus

 Klaus if you're responding to me, Let's not get carried away with what mine is, it may be ok on '54-'55 SA, but not on Plunger models, and I won't get involved with other S/A's on this.....but if you're responding to billierick, I'll stay on the bench

 The query was billiericks, I was merely offering a (probably wrong) sugestion;  ^ ^ ^
 

Dunlop alloy rims and a rather unusual rear drum brake which I can still find very little info. about except that it was made for the BSA QD rear with an alloy drum and steel QD center and a bolt on rear sprocket and an alloy backing plate. So far no one has been able to ID it whether aftermarket or factory race part? It is a very well made piece and of very high quality. John made an 47 tooth alloy rear sprocket for it but it came with a steel  56 tooth sprocket and the brake was on a Goldstar catalina scrambler originally.

[billierick]

hello, The B44 brake is not the same. The only thing that is slightly similar is the alloy backing plate. The drum I believe is steel on the B44 and also it does have a removable sprocket but it is held by 9 or 10 bolts. On my brake the drum is  alloy and the sprocket is held on by 6 bolts. The brake plate  as I said is similar but definetly not the same. For one thing the B44 plate appears to be cast alloy. The plate on mine is fabricated or stamped?? the same way that the standard plate is on a Goldstar. I have got to figure out how to get the pictures posted. I am not very computer savy so if any body can take me thru this process with baby steps I will try again.I did get all the pictures from my phone to a file in my computer but thats as far as I could go. Thx, billierick

If you guys go google and put in BSA Goldstar competition rear brake.  Go to images and then count down 8 rows 2nd pic in from the left is the backing plate for my bike and then count down again from the top 24 rows and the drum side of my brake is the first pic on right.Thx, billierick
