That was a brilliant film and a wealth of information. Well done!
Best batch of Bantam building bulletins from the Bristow Bantam barn. Bloody brilliant buddy👍
I should move to Banbury to finish off the rhyme!
Great work Dean. I've actually remanufactured the loctab washers for the gear selector mechanism recently for the very reason you showed. I don't really think there's a suitable off the shelf item that most customers would like, and most customers like replacement stuff to look the same. It's all coming together nicely mate......
Thanks Bones. It's good to know that you have remade the tab washers. The ones offered are pretty poor.
Best wishes, Dean.
Another great video Dean, plenty of hints & tips.
Wellseal, my favourite sealant!
Thanks Ian. Wellseal is good stuff for sure.
Best wishes, Dean.
Shall we all agree that this Bantam is going to be smoother than a Rolls Royce engine.

Hi have been watching your channel for a while now very interesting
We mess about with motorcycles not British well not yet
Italian bikes and Japanese
Some road and some race
DST racing projects
Looking forward to seeing your next video
Thanks very much. I have a soft spot for Italian bikes too.
Best wishes, Dean.
Good job brother
Thanks brother
Many thanks for the video Dean. Great to see progress on the bike. And, yes, I follow Dale and Allan Tweed (and Bones). Wonderful channels.
Cheers, Peter.
You're welcome Peter. I'll be glad to make a start on the new project soon. Best wishes, Dean.

Always glad to see you Cain
First!
Beat Cain by seconds!

why were the steel discs omitted from the flywheels
The D7 models never had them fitted. BSA dropped them for a number of years as they were troublesome and prone to break loose. Interestingly, they went back to fitting the discs on the later models from D10 when they were looking for extra performance.
Best wishes, Dean.
I never saw an engine(D7) that did not have the discs fitted but I believe you . I did a lot of engine tuning for racing Bantams and I used much smaller solid flywheels with oval con rods made by Alpha ,plus a horseshoe in the crankcase to fill the gap that the smaller flywheels left, I also used one very thin chrome plated piston ring and a Gardner carburretor
@@user-tn6sp2nz1g very strange. Service sheet 506 dated Nov 62 states they were not used from the D5 onwards. I know they were fitted again on the D10. My original D7 crank had never had them, no stake marks at all. BSA were good at changing things around so who knows? Personally, I think they are more trouble than they are worth. Stuffing the crankcase as you suggested on your race engines would be more effective in my view.
Best wishes, Dean.
That was a brilliant film and a wealth of information. Well done!
Thank you, I hope it helps someone out.
@@retromechanicalengineer I think it's a certainty that it will. I wish Grandad could have seen it. But then I say that about a lot of things.
