On the mid sixties 250/441 BSAs there is 1/8" spacer on the bottom engine stud, on the drive side between the frame lug and the crank case. This is often overlooked during reassembly, resulting in the lower frame rails being tweaked in.
Using a 7" length of M10 x 1.0 studding with two nuts on the inside of the rails the gap can be spread to the specified 4 5/8".
Once the motor goes back in there will now be clearance which can be measured accurately and a bespoke spacer made to take up the gap minus 0.002" resulting in minimal movement of the frame when tightened.
I've been studying this picture of a young Mr Fisher for longer than is probably good for me. I've always wanted to piece together something that pays tribute to the bike, but never had a frame suitable.
The frame is now here, James Holland has taken the two odd halves of a frame that I sent to him and jigged them into a mating pair. This will now be the foundation of the tribute Tiger 100.
A few posts below this one shows a Parilla Tacho that I confessed my lust over. In the year or so since that post moves have been afoot. I have had a pair of Bantam Speedos reworked and am now the proud of owner of this fine pair. Both are calibrated for use on Triumph Twins, the Speedo to a pre unit gearbox drive, and the Tacho has been modified for a timing case drive.
I think, just maybe, that this is the only pair like this in existence.
