    Congratulations on the channel growth mate, well deserved. I'm glad the racing season is coming, race bike content is always good. Great to see three generations of Bantameer at work.
    Best wishes, Dean.

      It sounded a lot better after I got the main jet right which wasn't on the footage..........

    Thank you for that it was brilliant as ever. Well done on 1000 subscribers, you deserve it! The sound of a two stroke engine brings back so many memories. As kids in the 70s Dean and I would often stay at our Grandparents. The both of us top and tail in the same bed. At the back of their garden was a big metal fence with a long straight road beyond. Teenagers would race 2 stroke bikes up and down there late at night, we would hear it through the open window. Sounded just like in your film. Great to see the young ones getting involved in the workshop.

      Hi Mate........Had a good chat with Dean last night. This bike is so loud! We'll take it off to the special and secret Oz Bantams testing area (4Km NW of Seaspray Grid Ref.......) and give it a run over race distance with some extra gear put on such as tacho/speedo and head temp sensor. It really does go well and we are currently 1/2 way through a build for a similar engine. The casting side is going well so watch this space. It's apparently a good way to up your subscriptions!!! Take care mate chat soon.

    As always, an education and interesting to watch. Followed you via this channel for ages. One of the few sites I don't 'fast forward' on and if memory serves, think I came accross you originally back in the day on the UK based BSA Bantam club website. When dosh permits will be contacting you regarding my D3 engine that is currently in pieces. Have a heap of new parts from Rex Caunt, however my brain knows what needs to be done, but, my hands and tool skills are somewhat lacking!. 🤣 Maddog, Melbourne. Keep the clips coming.🙂👍

    I once had a Bantam, that was a bit of an oddball. I think??? it was a 175 but never realy knew. it had no lugs on the frame or on the top fork yoke. it also came with a oversize cylinder head that had 2 spark-plug holes. Plunger frame with no spring shrouds and no provision for a head light. No mounts for either centre or side stands, though the green paint work was in good condition, My problem was I could never get it to go (even when towed behind a car). It was a fun (waist of time) project

      You should have tried one of my electronic ignitions.

    As some one who has built and raced Bsa Bantams for over 25 years im sorry
    to say that's no racing Bantam Sir ,to day a racing bantam is either water cooled read valve or large finned alloy with matching heads CR gearbox with beefed up clutch full flywheels with matching cases mikuni flat slide carbs disc front brake etc etc

    • @OzBSABantams
      @OzBSABantams  4 месяца назад

      Your obviously English...............Firstly, my brief from the customer was to build an engine that replicated the original engine that was in it built in 1953. Secondly These are actually Bantams unlike what is raced in the UK. Thirdly AMA (Australian Motorcycle Association) rule prohibits the use of the following ........Flat slide carbs......Water cooling if the engine was originally air cooled.......Reed valves if it never had them..........Disc brakes if it didn't have them..........you can't change the stroke of the engine. If you don't believe me check it out for yourself. This engine does have an 8 spring clutch, CR gearbox and other modifications. The engine I'll be building for myself will have a large finned barrel either an original modified or scratch cast. About the only thing original Bantam on those "Bantams" you race over there would be the primary cover. So to even call them "Bantams" is a bit loose.............

    Ever stuck a power pipe on one of those?

    • @OzBSABantams
      @OzBSABantams  5 месяцев назад +1

      Yeah I have. The whole point with this bike is to retain as much of its originality as possible. The customers Father-in-law built the bike around 1953 long before tuned pipe technology was available in the West. The bikes I will build for us will have tuned pipes and I've built tuned pipes for other Bantams I've done.

      I'd say that has everything to do with your device settings and not the video..........

    These were war repatriation from dkw , except the dkw was superior, like bristol cars were bmw copies

    • @OzBSABantams
      @OzBSABantams  5 месяцев назад

      Yes that's correct.......Copies of the DKW RT125 were built by Harley Davidson, Yamaha, and about 4 other manufacturers.
