    Aargh, my bad! Didnt measure opening so have to estimate: About 5.5cm x 6.5cm on open end. Length is accurate, 20.5cm from powerhead gasket. Those holes on sides of tuner are 12mm each. Excan is full of 8mm holes on upper end.
    And offcourse little grinding downwards from P/h gasket with everything put together!

    What is size of the throat at rear on those carbs? I have 2 sets of 60hp carbs but they have 44 jets and would like to run them on an old 49ci motor but keep hearing that they are too small?

    They look fast, but do they deliver.......

    Looking really nice.

    Did you machine those stacks? Or were they off-the-shelf item?
