    I have a UK model 1100c as in the topic. The manual says the UK model has 125hp whereas the USA
    model has 147hp. Does anyone have an idea where the power output is restricted? The same carbs are
    listed, with the same jet sizes. The same ignition advance is also listed for both model, except at
    idle. How else could they restrict total power output?

  2. Only early UK ZZR1100s were restricted to 125bhp.

    The restriction was in the carb tops, and changing these for ZXR750 tops
    allowed the slides to move that bit higher and liberate the extra poke.

    If yours has flat carb tops, it's restricted. If they have domes on
    them, it's not.

    It is restricted by the carb tops. Look at yours (the black plastic
    cover on the top of the carb) and if it is just a couple of
    millimetres high then yours is restricted. A full power model has
    carb tops that are about one and a half centimetrs high.
