    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.

    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.

      If it works Kev! I could buy a proper clutch tool but instead I use whatever scrap I had to hand!

    Shall we all agree that this Bantam is going to be smoother than a Rolls Royce engine.

    why were the steel discs omitted from the flywheels

    • @retromechanicalengineer
      @retromechanicalengineer  6 місяців тому

      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.

      @user-tn6sp2nz1g 6 місяців тому +1

      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

    • @retromechanicalengineer
      @retromechanicalengineer  6 місяців тому

      @@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.
