Fork leg stud

[Worty]

Mornin' all.

Quick question: do any other BSA models share the same front end parts with my '61 Flash?  I've seen some sliders from a B25 that look similar and may need the 'pair of trousers' fork shroud at some point (not sure of its proper name).

   Hi Wortluck

   Head over to those nice folks at Draganfly's Website.  There is a whole load of stuff about BSA Forks.

   Look up your  fork bush applications, then you can see which bikes use the same diameter stanchions as yours, and from that, possible fork sliders. Fork sliders will vary with mudguard mounting lugs, brake anchor lugs and front spindle mounting.
 
  I reckon B40 sliders would be a good start if you need a clamp on spindle.  Draganfly have a table of Stanchion lengths,  but  B40  stanchions are too short unless you have a 21" wheel or want a Lowrider stance.

 Yes, the headlamp mounting was known as "Top Hat and Trousers. " The earlier one is called the "Diver's Helmet" or "Cowpat" depending if you are selling or buying.

Good advice Swarfy - thanks! Draganfly are good.  B40 sounds good - mine has a 19" wheel and clamp on spindle.  The upper mudguard attachments are by way of two studs that protrude from the slider with the lower stay attached by a single, threaded lug.

Thanks again for the info!

Hi wortluck
I think you maybe looking at the same set of fork legs as me https://www.ebay.co.uk/itm/BSA-B25-Triumph-T25-fork-sliders-bottoms/183510068454?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l9372, I meant to buy them last time they were for sale and missed bidding on them. They look the same as mine (60 A7, 61 A10) but who knows it was worth a punt as the only other listing for forks like these was for £425 (they were complete with yokes and every thing). I don’t ‘need’ them just putting together spares in case of a mishap
I followed Swarfy’s advise but could not find anything on the dragonfly website, the part lists of the both bikes don’t show the same forks as in the listing.

  Hi Angus
                  One of the problems with such listings is that often the seller does not Know what the part is from, so uses an educated guess.  Then states " The pictures form part of the description, you must be your own expert, no returns etc." But without accurate measurements and good pictures as a buyer you cannot make an informed decision, as I found out a couple of weeks ago with a magneto end cap. Remember, the item must not be mis-represented and the description must be a accurate.

  Fortunately if you stick to the rules as a buyer, the organisation will get you a refund, simply by debiting the seller's  PayPal  account.

   The item must do what it is supposed to do, unless offered for sale with a proviso  that there is a fault.. For example it looks like a camshaft, fits like a camshaft, but if it won't turn because it is bowed, then it really is not a USEABLE camshaft.
                           Neither is a fork slider with a dent that the seller forgot to mention.

 Swarfy.

The ebay forks are not B25, which would have a hole in the base for damper rod attachment, different lugs for mudguard stayes and no studs and would not have a circlip groove. Certainly look like A10 forks.

B40 bottoms can be used but the brake side has a narrower spindle clamp surface due to the position of the brake plate being closer to the right leg. The later B40 part does not have a circlip groove and needs the A65 type widget to clamp the top bush.

[Worty]

Absolutely spot on guys, these are the ones I had my eye on.  Reason being, one of the studs on my fork legs has sheared off and I wanted a replacement whilst the other is being repaired.  I'd definitely agree that they're not B25 and look very much like A10/A65 (A65 1962-1965 only).  It also seems apparent that only the left side of the B40 matches with the A10 as the right (with the brake plate lug) is a different part number.  For the record, the A10 part numbers (swinging arm late models) are 42-5141 and 5142 (correct me if I'm wrong).  I won't bid against you Angus, but if they are the right ones, I'll put in an initial bid.  I always think that it's members of the forum who outbid me on items (like some ATD bits and a full set of forks recently!), but I always try for a bargain.

Cheers

Hi Wortluck

As I said I do not 'need' them, which leg do you need as I have the right hand one (looking forward from the seat) with the brake anchor. I would be interested in this pair as a spare so maybe we should co-ordinate our purchase effort, or maybe I could purchase them once you have repaired yours. I have a tread in not great shape on the left hand one, still usable though. I do not want to be bidding against a fellow forum member.

Hi Angus, used to live in Rattlesden near Stowmarket.

I actually need the left side.  The studs on that side were much thinner than the right (brake plate side) so wondered if they'd come from another model or just bodged up by PO.  There is another brake plate side slider on Ebay from Bradford for £10 + £6 postage but it's in shabbier condition by the looks of it (and not the one you're after).  No problem getting back in touch to sort something out, but I don't have a time frame for getting the work done at present.  If you're keen to buy, let me know if you're going to bid and I'll back out.  The first bid you see is mine.

Cheers!

Hi Wortluck
I will not bid. I did mean to bid when there were on ebay last week, but forgot and missed the auction end. You obviously need them and I only want them to sit on the shelf. If you don’t mind I will keep a record that you may have a potential spare set and if I need them and do not find alternatives I will get in touch to find if you have had the work done. Hopefully I will never need any.
good luck

[Worty]

Cheers Angus, that's really good of you.

Of course, if I end up with a spare set, I'll let you know - will have to win the auction first though!

I know this is happening already but, with original parts becoming scarcer, it would be good for forum members to continue to trade parts that are surplus to requirements.  Just wish I could find a barn full of decent spares then I could retire!

Well would you believe it. Went to a local little autojumble this morning, 2nd stall and what purport to be a pair of late A10 fork sliders. Turns out that he had two left hand ones, both in nice nick so I bought one, I now have a set as spares  . Wander around the rest of the jumble and on the last stall is a proper pair, they have been chromed which was in good nick and looked OK but I had my pair now so passed them by. I have looked at Kempton and Stafford for these and just not found any, none at all, then like the proverbial bus they come alone in pairs
Wortluck if you don’t win the ones on Ebay I have the details of both vendors and both were slightly cheaper than the ebay ones, although I have no idea on postage.

[Worty]

Brilliant Angus, thanks a million.  I'm hoping for the Ebay ones but will take up your offer of info if I don't secure them.  As I said, it was the left that I was after, but I won't mind having a spare one or two - can always send them on for a few quid.

Funny, but I thought they were like hen's teeth, now they seem to be everywhere??
