    changing the pistons isnt gonna do anything for you. You need the riva ECU and 12r cams. 12f pistons are just made for a higher compression engine. If you do get the ECU and cams, you will be better off looking into JE pistons or something. since the 12f pistons are OEM they wont last to long. The piston skirts will break.

    its not worth the trouble if you want to do something like that swap the zx12r cams from the ninja over and do the timing mod.

    Please for the info

    When you say Cams from 12R do you mean from Ninja bike or the one from Riva Racing Endurance kit ?

    And does it fit in the 15f ?

    thank you
