    Yes it can be drilled and tapped to us on FZR/fxsho. Have several already done. As for gain on a hot day my ski woul lose about 100-150 rpm with 82.5 exit nozzle. Would then install my 85 exit nozzel to get my rpm back and speed. Bob

    The oem nozzle bored out performs better though.
    I can have my machinist cnc bore a nozzle to whatever size for a small fee if anyone needs.

    $40 and about $10 for return shipping so $50 shipped back to you. and its also a good idea to do the steering nozzle aswell to match. the round steering nozzle out performs the oem oval one, WHEN combined correctly (example) 85mm exit nozzle and 90 steering nozzle.
    pm me if interested.
