    Post Pat's GPR Mini Build Helpo!

    Just got home, thought i'd post this up before i crash

    My goal for 09 is getting this GPR to run 70-72 MPH....

    From my basic knowledge and research, to run my goal...i need..

    1.Cat Removal, D-Plate and sensor
    2.Milled Head to 150 PSI
    3.Flame Arrestors
    4.Re-jet to
    • 110 Pilot jets, 1 turn out on low speed adjusters.
    • 125 Main jets 1-1/2 turn out on high speed adjusters
    • 1.5 Needle and Seat, 95 gram spring (Dull Silver) 42-45 avg. pop-off pressure.
    5.Ride Plate..maybe Jim's plate
    6.Intake Grate...Probably Riva
    7.Solas Impellor (14-20????)

    Not looking to do the Jetworks, not worth it IMO.

    My plan is to rebuild the Carbs during the winter because its been hesitating out of the hole and then hauls ass.

    Any other suggestions/help would be appreciated!

    FYI-I want try and keep this ski reliable and safe...So i really dont wanna go over the board with modifications

    The reinforcment should be #1 on the list.Change out the intake grate second,as a matter of fact,change it right away,stock ski or not.
