Singles / Re: !950 b31 petrol tank
« on: 16 January, 2018, 21:15:01 »
Hi Guys
Thanks for all the info. My tank has the small oblong BSA badge with wing. Underneath at the front there is a link pipe connecting the two sides of the tank. According to Julianís parts book this link pipe was only fitted on the M series part No 66-8285, my sprung 31 should have tank part No           65-8161.
Does anyone know what the physical difference is between the two tanks. The reason I ask is that the tank needs re chroming and repainting if spend the money on this tank will it look right or should I look for the right tank

Hi Guys
I need some advice about the petrol tank that come on my bike ,the frame is a 1949 plunger. Is it the right tank if it isnít what is the difference.  As I am trying to fit a solo saddle I thought I had better check that the tank is ok size wise and shape etc.
All The best

Singles / 1950 B31 Saddle
« on: 04 January, 2018, 16:57:07 »
Hi Guys
I am rebuilding a 1950 plunger B31, and want to fit a solo saddle. I have brought a wasselll one from Dragonfly (large lycett type) but when you offer it up with the springs on it appears to be the right width but to long (about 14inches) to fit the cutaway in the tank properly. Has anyone got any pictures or measurements of the correct one or has anybody fitted an after market one

Thanks

Hi Julian

Hi Julian
Thanks very much your reply and a chance to look at your great parts book. Looking at the parts list for the stand and my casting No 29-48?? it looks like I might have the wrong stand. Do you or, anybody, know what the physical differences are as the picture looks the same.

PS can you buy the parts book you use anywhere as with the pictures and numbers it's easier to see if you have the right parts fitted in the first place. Once again thanks,

Hi Guys
Can anyone give me some technical advice please? I have a 1950 B31 which I am trying to renovate. I brought a rear brake rod complete at the weekend but when I got home and checked it is was longer than the old which is 20 inches overall. Can anyone the correct length please.

Best regards

Hi Guys
Pictures to go with the previous words 3 of the cylinder head and 1 of the cylinder. Julian said the cylinder number denotes a 1953 cylinder (should be 1950),.
Thanks everyone for your help

Hi Guys
Thanks for the replies But I am afraid I still need help. How can I tell if my cylinder head is the right one (1950) is there a part number stamped on it or what does it look like compared to the post 1953 one, also the comparison of the cylinder.
On the top of the cylinder is a spigot that goes in a register on the cylinder head this fits ok but the other two machined surfaces where the threads are on the cylinder head and the loose bolt holes on the cylinder do not meet any ideas
Sorry to be a pain

Hi Guys
Thanks for the replies and the information. It looks like the engineering work on my engine may be more than I am capable off , if thatís the case can anyone recommend some ware or someone who could do this. Also on removing  the rocker oil feed banjo bolts I found that they have a large hole the same as the return one could this be a later modification or has someone just fitted the wrong ones.
Thanks again

Hi Guys
Can anyone give me some technical advice please? I have a 1950 B31 which I am trying to renovate and started to take the engine apart. Taking of the cylinder head there was a thick head gasket, I did not think there was one, can you tell me if they are the right parts. Iron head and cylinder casting No on head66-1157, casting No on cylinder 65-1703 or could be 66-1793 or the 66 could be 65. And worst news on the inside of the cylinder liner, timing side and 2 deep groves about the width of the gudgeon diameter I take these are not meant to be there. I f the liner is gone can theses still be got or repaired. I live in Dorset
Best Regards
