    Fuck you would not believe the conversation me and Seymour had with Dave nthe ferry for the last BoB trip. Even I who would have a barn full was trying to convince him to sell some so he could finish the others.
    Don't you look at my accountant.
    He's the only one I've got.

    Speedpro, i believe that type of pump turns CW and need buggering about to rotate CCW (disclaimer: intertube copy and paste fact)

    Found this stuff while looking for something else down at the storage cow shed. My old thinned down Wade, FZR head and the new AMR supercharger. The FZR head was destined to be the beginning of a 100cc twin fourstroke SC, might still happen?

    How can you call this a real engine, x2 = 100cc. Thank you Speedpro for the FZR parts.

    What would be a good frame to put the engine in? I'm talking cost effective ( cheap ).

    3ln FZR250 would be easy and cheap, good size rims for slicks, room to lighten it, big enough for old men to ride

    the rules are not clear on this
    The maximum capacity for rebored engines shall be:
    F4 2 stroke 55-100cc - 104cc
    2 stroke 55-125cc air cooled - 130.5cc
    4 stroke 55-150cc – 158.09cc
    F5 2 stroke 0-50cc - 53cc
    4 stroke 0-100cc - 104cc

    100cc SC is f4 not f5
    If you applied the +2mm method for max overboring you may well get a bit of a lift as the pistons are so small

    on a std stroke 124.84cc
    on std stroke +2mm 135.48
