    Does this sound OK for Carb Tuning?

    GP120R, Milled Head, D Plate, Stock CDI (will add R and D Later)
    Carbs redone by Island
    110 Pilots
    125 Main Jet
    1.5 Needle/Seat
    95gm spring
    No Acc. Pump
    Riva F/A's

    Lows-counterclockwise 1 full turn

    Highs-#1, #2 counterclockwise 1 1/2 turns and #3 counterclockwise 1 3/4 turn.

    Will adding the R and D change this?

    Thanks
    T D

    I'm not going to second guess Carl. If it were my ski, I'd want 120's on the highs - but 125's are certainly safe.

    I ran 125's with the chokes removed I had great results with this. I would run 120's if you did not remove choke plates.

    I'm more or less wanting to make sure I have the Hi's and Low's turned appropriately. God Forbid I lean this thing out and melt a piston. I would rather run a little on the rich side and just live with it.

    IMO, 125's are very rich for an unported 1200. So I think you're very safe.

    No porting but he is running an aftermarket ignition. That will require slightly more fuel right ?

    EDIT : I see where the ignition is not installed. The difference between 125's and 120 mains is approx 1/2 turn.

    You are definitely on the fat side on the highs you will be plenty safe there. The lows are right where I always set mine.
