    I was at the ONE Moto show in Portland Oregon earlier today, 3 day show, people from all over the US and world were there (its a BIG deal!) and should be a bunch of pix and videos online shortly, I might soon post some pix, But thought of this thread as there was several UNIT BSA bikes there at the show but a very nice well build BSA Unit twin Bobber similar to this frames lines was there. I took some pix.
    (Will post soon in next few days, It takes a bit to convert the files and resize)

    I know Ed G, He helped me out a with a bunch of info on my 1947 Villiers Famous James. Seems like a good guy. I have never used his cranks, But theres enough people out there using them they must be okay, But be advised, Most of them are rephased. 270 degree which helps and makes a very interesting motor for many reasons. But its not for everyone and a bit complicated.
    You have to run a special cam and ignition to do it, I think he offers all that, But instead of a 350 deg twin its rephased like a Ducati*.

    * The reasons for running a 270 degree crank is it has some advantages, The vibration is not as bad, but it HAS to be dynamically balanced, But the 1-2 stroke cancels out the vibration a bit so it revs very smooth and can run higher RPM. We did this on Sir Eddys LSR Norton to run up to 11,000 RPM.
    Eddy built his crank with machining. Ed G cranks does his by cutting and welding in a Jig, which Sir Eddy was horrified at, But clearly does work, but I doubt they can run as high RPMs, but clearly he has had good luck with them, Some guy on BritBike runs one and has posted high power numbers.
