    SMW,

    The Dynafly 14/20 is too big for a stock FXHO ... I lost 2mph and it was sad outta the corners ....as have a few mates and they got the same results.

    It needs the full RPM kit to turn it really. I tried it then with just trumpets, rideplate, free flow air filter and still no go ...

    A repitch to 13.5/20 or even 13/20 and work back up would be a place to start.

    I put in a Concord 13/20 and lost .5-1 but holeshot and mid was much improved.

    Regards
    Anthony

    FXHOR,

    If you are installing the full RPM kit from Riva (or R&D Performance for that matter) use the Dynafly 14/20, as recommended by Rivs, for that kit.

    It will give you between 62-64 mph against the 59mph of the stock craft. I've run my 06 stock ... 59.27 (gps). Both of them !!

    If you are just after more speed by only an impeller change there is NOT a prop available to do it. If you use the Dynafly 14/20 you lose speed and load the engine unecessarily because in the stock "state of tune" it wont turn it.

    The Concord 13/20 (for stock craft) I used was a special batch by Solas ... as far as I'm aware they are not available ... they might be now ?

    Anthony
