    Hey Tommy, IMHO I think the 1300 should have come this way from the factory. Smooth crisp response in all throttle ranges, no lag or blubbering, no more flat spot @/near the 5700 rpm range!

    R1 reflash.
    Stock rebuilt engine with ProX pistons and Millennium repaired/replated cylinders.
    New head, stock compression
    Riva Kawi adapted FA
    Riva Blue hose free flow.
    NO jetworks!
    *increased rev limit* with the oem impeller you could see 7400. with a tweeked Skat impeller it came down 150+-., and increase in speed. The new owner of the ski said it was good to go...


    Personally, I think it was worth the $$$. For a stock rebuilt set up with the R1 the ski was reliable and predictable. It launched hard like it had jetworks mod. and of course final speeds are how the ski is dialed in with the plate, tabs etc etc...

    now , if you are going to add mods, increase compression, it is best to speak with Bill Chapin.

    The R1 is a stand alone ecu and not run with any additional fuel controllers for this set up...
