Title: filter rubber
Post by: wilko on 22.04. 2014 00:34
Anyone know what this fits?  http://www.ebay.com.au/itm/171235725305?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

 looks like A7 & Star Twin, and prt # 67-4596 matches that- A10 is apparently different (67-4589)

There's a similar one also on ebay, part no. 67-4589 for A10 plunger, but is it the same?

 my guess is it's different because the A10 inlet sits slightly higher because of the longer stroke- but am only guessing, I'm sure plenty others are more knowledgeable

I guess I'll be good and not do this, but it's very tempting to ask the seller about 20 questions.  >:D *lol* >:D

THE correct one for an A10 is here:

http://www.ebay.com/itm/BSA-A10-650-Pre-Unit-Carb-Air-Filter-Connector-Rubber-/121250827134?pt=Motorcycles_Parts_Accessories&hash=item1c3b1ccb7e&vxp=mtr

You can buy with confidence on the following assurances:
It's a direct copy from one I Supplied to this guy who then made me 3 of them. They fit perfectly on my pre unit A 10 Plunger. (1951)
I had previously purchased  4 wrongly advertised ones before finally finding an A10 not A7 one.
You can see the "Bubble" in the top of the shape. The "Bubble" sits slightly above the oval shape that connects from the air cleaner. Any round connection that does not have a part of the circle sitting above the line of the oval connection from the air cleaner will not fit an A10.
Hope this helps.
