help wanted with a mystery :-)

[raymo]

Hi Trev, 
it could be a CA7  as I can only get the number section of the original frame number  just assumed it was  a GA

the lower forks are different from my old gold flash as I put the TLS from a  B25 Starfire on that.. I also have a Starfire now and noticed that I cannot do that on this frame/folk set up as the the front spindle screws into the left fork lower, rather than having clamps

will get some more pics up this week end when I  pull it out from its resting place :-)

getting quite fired -up and looking forward to sorting this bike finally... hope you guys keep on my case so I dont let the old girl down :-))

Well I think we can forgive your 'thrashing' the bikes in the past as your now working on them and getting them up and running once again! Your youth stories are always a pleasure to hear so this compensates. Good stuff lads.

Nice pics Ray... It dont look in too bad condition so should be an enjoyable restoration. I dont know what to say about the end feed conversion I've heard horror stories from other lads in the BSAOC, from another Ray in fact. The good old timing side bush... although crude and constantly criticised has not done too badly if fitted right in the first place, good clean oils and ridden sensibly, they have often covered many thousands of miles.

Hi LJ,

 Will give it all a good looking at, the bush may be ok, so may live with it, too early to tell yet.
 I will start at the top and work my way down engine wise..

 Not happy with the endplay on the crank but need to measure it, also think there is a bit off play on the piston small /big ends....

 it all moves.. it is  all covered in oil  ( I recall taking the plugs out and squirting oil  down the bores before banishing it to the obscure part of the garage while I turned to the dark side of reliable house trained Japanese motorcycles )

 Still puzzled about the frame, as CA puts it in the 50s

 will post more pics.. Thanks again guys

Cheers

Ray,
        when you get full access to the bike, try to slip a finger between the battery platform mounting brackets on the frame and the cross member below. If your finger slips in to about the first knuckle, it is CA7 or GA10.
If the frame has only one set of cast lugs on the front engine mounts and a steering lock socket on the head stock and all frame welding is oxy-acetylene, I would say it is a 1955 frame.
On EA7, FA7 and GA7 frames, the finger test under the battery box brackets results in the finger tip only being able to be inserted.
As a matter of interest for some, frames were oxy welded until somewhere in the EA7 series, probably until the sidecar mount was fitted in the rear loop, and then were electric welded.

well took some more pic and  when I zoom in on one I took of the frame number, I can make out   ?A7 10638  the frame has the hollow swing arm and bracket on the left for the cross over brake cable to a full width drum, even though it has a QD half width drum on the rear with a rod operated brake, has the steering lock too

Raymo,

Your brake pedal is mounted in the sidecar rear attachment point. That is why your brake rod is bent and why you probabaly find it uncomfortable to bend your ankle enough to operate the brake, as the brake pedal is too close to the peg.

You have a frame for cross-shaft brake operation after they stopped having both the hole for left side while also having the hollow spindle. In the photo you can see approximately where the hole for the brake pedal should be in the vertical frame member. But it's not just a hole, there would be a tube through the vertical frame member forming a boss for the pedal to ride against.

I had the same problem and corrected it. I can provide photos of my work, just not this minute.

Hi Richard and Ray,

I have also been playing with this, and as you say the mount for the GS pedal is slightly high and to the rear when mounted in the Sidecar mounting point. Thats a pain, i have (when i get time) playing with the idea of making stout plate that fits in the intersection of the 2 frame tubes and bolted to the sidecar mount and somewhere else?? in order to get the pedal mounting closer to where it should be, Now whether all the effort is worth what i actually gain im not sure!

Ray i also notice your going to have the same issue as me this the chainguard! i have a RGS (single sided hub) chainguard, but the wrong mountings on the swing arm!

I just want to change these things tastfully so i can make my bike look correct, without the pain of Replacing the swing arm, or welding lugs here and there as the frame is nicely powder coated by the previous owner (thats as far as he got). Maybe Richard has the solution!!
