Mossy, how'd you do this? 
Did you weld the circle onto the square (tech talk, I know)? Can you clue me onto the steps and the specs of the materials?


Rolled a piece of aluminium into a 64 mm external circle twice as long as the end result then hose clamped the piece that would be unused. I then shaped the edge on the side to weld so that it fitted into the original square and welded the 2 together.

Couldn't see where you have it on the pics.

1. Insulation splits and causes shorts.
2. Wires break.
3. Nothing actually goes wrong (if you're lucky!).

I've been wiring motorcycles since 1981 and that curve makes me shudder.

Custom made for $80 nzd in mild steel about 40pounds uk.

Once its made he will upgrade me to stainless if I like for double that.
I think hes likely to be selling them if anyone is after one now he has the jig etc.
Theres 2 so far waiting to see what its like with the idea of getting one.

Will post a lot of photos once I have it.

just an input

you might notice that the inlet pipes on the standard muffler collector are staggered in length on an 8 valve  , on opposing sides to allow for clamp fit up

this could be a good thing to think about as it is noted that the welded pipes on later 16 valve models with stainless tubes seem to crack ,

I have a suspicion that the odd lengths of the pipes and heating effect , along with vibration causes this ....perhaps there is benefit from the clamp fit as it allows the pipes to move slightly and avoid the stress and eventually cracking .
unless you intend the fittup to be spring loaded and interference fitment

just a thought

Yes we have allowed 4-5mm gap in closest pipes for clamps to fit even side by side.

KafeRacer wrote:You are probably right,  It is just hard to comprehend the fact that the BSK rearsets will cost more then the whole donner bike!  I only paid 500$ Cdn for the donner, mind you is was not running and was in many pieces when I picked it up.  Cost about the same a a bsk rear set as it sits in the photo.
