    951 rejetting

    I have 46cc miller head, rd f/a, tdr waterbox, and will probably get rinaldi reeds. How should I go about rejetting?

    Don't even bother with the tdr waterbox it will do nothing for performance ,it will just piss off the people you ski around, they are barky load.
    The miller head is ok but make sure you are running .67_.70 th squish or you will have to run higher octane fuel.
    The rinnaldi reeds are good but use the 10 mm spacers as well or they will chip the corners after 10 hrs or so
    R & D filter is ok but proks are better and easier to get off and on but its ok to use
    Jetting I would go with this as its a proven winner
    Some say change the Needle and seat but I have never done this on a rec ski.
    Needle and Seat 2.0 mm, pop off needs to be 19-20 psi no higher
    Accelerator pumps working use 87.5 lows, pumps deactivated use 95 lows
    highs speed jets 165 or 167.5 if you are conservative
    Low speed adjusters open 1.5-1.75 turns
    High speed adjusters both closed
    If you can have the timing advanced 1-2 degrees this will wake it up
    Even better is a lightened flywheel and machined down PTO
    Then a white pipe is your next option and you dont have to change jetting from above either
    Prop I would have the stock prop re pitched so it gives you approx 7100 rpm in flat water and accelerates from idle to 7100 with a linear rev range
    Thats how we set 951s up for rec
