Britbike forum Forums British Motorcycle specific Brands Bsa bulletin board West coast hornet TT pipes and rear mounting plate

Would anyone have images and possibly even detailed drawings of the rear brackets for the mounting brackets that support the tail end of the exhaust pipes on the underslung west coast TT pipes.

Thanks in advance.

I'll look at one today, could probably email you a shot. Don't have one off a bike right now.

That will be great Leon, thank you.

I pulled one off and traced it. 6 1/2" long, dog bone looking ends are 13/16" circles. Shank in between end circles is 9/16" wide and straight. Thickness about maybe 5/32". Forgot to measure holes center to center. If you want a picture, beaverbikes at gmail dot com.

Win,

If you want, any and all pictures of the setup can be emailed to me and I will post them here for all to see?

Jon I'll do that, have to dig out my older computer first.

Sounds like a plan!

@ Jon and Leon, that’s great, thank you both very much!!


Perfect, thank you. I would think the bolt holes would be fairly self-explanatory. More so with the photos?

Thanks Gary. I gotta say, though, I've only ever had four of these pieces in my hand, but all four were flat.

That’s great Gary, thank you.

Out of interest, which end does the bend go to? The pipe end or the frame end?

Thanks again.

The bend is at the top at the frame and they go on the outside of both the pipe and the frame. The original factory holes are larger than the bolts to allow for adjustment since the pipes fit a bit differently on each bike and each side.

All of the originals I have seen had the bend. None were flat.

Both of them on my 67 are dead flat. Both of them on a 67 basket case I saved last year were flat. Both with original pipes.

You have both been really helpful with measurements, I will make some stiff card mock ups using the dimensions and see if it requires the bend from there I can do it with the card before making the final metal item.

Thankyou again.

Allan, looking at those measurements, I reckon BSA used the C15 rear brake torque arm and put a slight bend in it. The part number is 40-6034 and someone is selling them in unpolished stainless on e bay. Wouldn't be the first time BSA re used a part for something else.

Thanks Vic, price isn’t too shabby either (certainly compared to the cost
of making one)

I’ll buy one and see how it goes.

Allen…..Peter Quick sells used 40-6034 for $6 US.

Well he did as of yesterday…if they actually are the same part the price might go up!!

Gordon in NC

A good reason not to buy from him if they did go up in price just off the strength of that, but I would be surprised if he did that. Since there are so few west coast hornets out there and the pipes seldom come to market, I doubt they would be much call for them.

Shipping from the states, customs etc (parcel force in the UK would even add a handling charge of a fixed value) just makes some parts orders not worth purchasing from outside the UK. If it’s something special then of course that’s different or if your putting a big order through.

Allan, I was only kidding about the price raise. Peter is a straight up kinda guy and I do most of my business with him.

We are very lucky to have someone like him in business.

What I was getting at is if they are the same part, there seems to be plenty of them out there. Heck I have some I’ll never use in my shop. ( but will probably go to Wade someday with the rest of my C15 stuff) Yea C15 bits in the UK should be on every street corner.


Gordon

Gordon, you're right there are loads of them at every autojumble and on e bay. I' m fascinated to see if they are the same part hiding in plain sight.

[quote I doubt they would be much call for them[/quote]

It's surprising what sells and what doesn't. I thought that when about 3 years ago I bought a job lot of NOS BSA and Triumph parts to find to my dismay that it included 14 right hand TT Bonneville exhaust brackets. I now have one left.

I’m 99.9% sure mine are from a C15. If I have time tonight I’ll drag one out measure and photograph it. Doesn’t prove much but it could be used to compare to Gary’s.

That is if someone doesn’t beat me to it.

Gordon

Gordon, I beat you to it. I remembered I've got a complete NOS C15 Competition rear hub in a box in my hoard, with torque arm. Well it's official, 68-2826 is simply 40-6034 with a bend. The dimensions are identical to Gary's diagram. Hiding in plain sight after all.

this discussion took an unusual turn, but I have to eat some of my words above. The bracket I pulled off my 67 to inspect was completely flat, apparent when it was placed on the bench. But I figured I should look at the other side, the right side: that one does have a bit of a bend. A more gradual bend than in Gary's picture, almost from the center. Now I have to look at that other 67.

Hope this isn't clouding up the thread BUT......I'm going with Vic's assessment that they are the same part. I finally found mine ( they were well hidden) I'll take some photos and share here in a bit.....got some honey dos to take care of first.

BUT........I did measure one and it was exactly the same (sans bend) as Gary's. Photographic proof later.

I won't use mine......kinda promised all my C15 bits to Wade. BUT I can be bought.

If you're going to use them on a C15.......$6 plus shipping

for use on a West Coast Hornet.........$75 plus shipping

If you can find a use for them on a Gold Star........$250 and I'll cover shipping.

NOTE: Prices are for ONE (1) bracket only.........don't try to low ball me......I know what I got.
