    Need advice on rejetted carbs on stock gp1200r and primer kit

    Bought this gp1200r last year and it would only top out at 55mph and would bogg down often. I pulled the motor and carbs this winter, put in new mounts, reeds, starter, black box, and gone pre-mix. Carbs were in horrible condition. I was surprised this ski even ran. Compression is 110 all 3 cylinders. Anyways, I'd be happy to get this ski up to stock speed for now.

    I've never worked with carbs before, but have learned a lot on this awesome website. Got these jetted carbs and a primer kit from MRBTD. Rejetted to 122.5 mains, 110 pilots. My motor is essentially stock, but got Riva f/a's, compliments of jeffntx. Ski already runs with a solas impeller, not sure of pitch.

    Anyways, how do I connect this primer kit to the third cylinder? Does the primer pump connect to the reserve or the on line? Should I plug up the oil inlets? Do I change oil ratio or stay at 32:1? Just wanna be careful not to seize the motor with these modded carbs.

    call me....You need to add that T to the return line. The the third carb just comes from the smaller T that goes to #2
