    1994 Sl750 - 72mm Bore (Overbore).....has anyone done this?

    Hi Guys,

    I have just bought a 1994 SL750 for a whole 89 (Im in the UK). It has good compression and runs but I have a spare set of stock size jugs/cylinders so....im thinking of buying a big bore kit to take the bore out to 72mm. Have any of your guys done this to your 750's and what were your thoughts regarding the resulting power increase?

    Cheers

    Andy

    not worth the money unless it needs it
    if you are hell bent on more power look for a 780 motor

    Absolutely correct ^^^^^^

    Not much HP gain from just boring a 750. The 780 porting is different and that's what makes more HP.

    Just as reference 750 = 80 HP while the 780 makes 92+ HP
