Hi Dave, yes dimensions basically the same with the Bully snail cams (405-420mm).
Don't know yet what these dimensions will be once aftermarket notched snail cams are introduced but I'm guessing similar.
I think Berry's idea with this swingarm was to make it adaptable between 250 and 325/350, hence the two allen head bolts 10 mm apart

My Honda swingarm from Berry also has the 2 allen bolts, i thought it was to give you different options ? Is your stand on the left hand side, if so i whish mine had of been made like that, it's a PITA when draining the oil on the TLR, because the drain is on the left & Berry put the stand on the right side :(

Mine on the correct side (right) for the Bully. If Berry fits those double allen heads to all his swingarms than I guess it is for adjustability depending on how big the snail cam is.

Early 325 barrel and head

I'm very much looking forward to when Greg has a nice 325 :Bultaco: set up for trials competition. The things he does setting up his twinshocks should make it very nice to ride.
It will also be great to know how it goes back to back against his :italjet: Piuma, as in which of them is the better :Bultaco: :shock: :shock:

Matching numbers Bultaco frame found!

Postby Greg Harding » Sun Oct 25, 2020 9:49 pm

Hi Everyone,

Just sharing that we found the matching (sort of rolling) 158 frame under the house at the :Bultaco: Emporium.

The 159 and 158 swingarms have different part numbers probably shorter on the 250’s to make up,with the shorter frame and forks, the 1 inch shorter wheelbase
With over 3 times as many 158’s produced than 159’s which seems odd to me but they were brought out around when those nasty ty175’s arrived and sections turned into mostly tight turns, anyway maybe they changed the bashplate Some where in the middle of production, all the 158-159’s I’ve seen haven’t had the slotted plate.
Cheers Ross

Ross, I see now what you mean about shorter frame, forks and swingarms, a :Bultaco: 158 is more :yamaha TY 175 size and dare I say it, like a :montesa 172. :!: :shock: :lol: :lol: :lol:

Also I can narrow the round hole to elongated hole change to somewhere between 158 01114 and 158 01581

No lottery win Ross but I am very happy with purchases and I hope I am not the only one picking up parts in these unprecedented times?

Greg there were quite a few different :Bultaco: rear hubs in the late 60s to mid 1970s.
I went looking and found one of those "all aluminium" hubs you had spoken about but it came without a motorbike attached so I don't know what it is from. Looks nice though. Here is the "all alloy" hub I found tonight:

and here is the back wheel from my 1968 :Bultaco: Sherpa T model 49. I think it is the same as was fitted to the model 10 :Bultaco: and model 27 :Bultaco: Sherpa Ts. The little spoke flange is riveted on.

And here is the hub that followed and was fitted to late model 49 :Bultaco: , model 80 :Bultaco: and model 85 :Bultaco: and probably lots of other :Bultaco: . This one is going on my model 85 :Bultaco: Alpina

Ye Olde Bultaco wheels

David, I know you said no motorbike attached but something tells me that the bike you are imagining is nothing like the reality, I will let you think about it. Here is some photos of :Bultaco: M49 rear wheel and what I think is :Bultaco: M99 but not sure, warning that might be backwards?:
1603792669634.jpg

The sprocket mounts and brake assembly are the same.

However the springs and shoes are different.

The axles and brake plates interchange but the spacers are different.

So here is my theory about the steel spoke mount on small side of hub, I think they were worried about the spokes pulling out of the hub. Also I am pretty sure that the 2 holes is where speedo drive goes?
