    Yamaha gp1200r carb jetting and tuning for triple pipes

    Just in the process of buying triple pipes for my gp1200r and would appreciate some guidance and the carb tuning.

    My mods so far
    Fresh built motor
    Trued and welded crank
    Carbs de choked with fuel return mod done
    Flame arrestors
    110 pilot. 125 main 1.5 needle and seat 95g spring , 45 psi pop off
    Protec 150 psi head
    Free flow exhaust
    Riva programmable cdi
    Fuel tap removed
    Fuel sender flap removed
    Primer
    Worx intake grate
    Solas 13/20 set back impeller

    There's probably some bits missing but all main areas have been covered. Any help would be ace

    First thing did you go back with nikicil cylinders. You need to break in the Pistons and rings before putting the triples on.

    Hi thanks for the response. I've done 20 hours on this rebuild so far. Two of the jugs are niskel and the center jug is sleaved. The jug was sleaved by previous owner aprox 100 hours ago. I was going to run it like this for the time being then as soon as some 1300 or bigger jugs come available up grade . That's if it hasn't popped by then. Hopefully with a slightly rich jetting, nothing to crazy it should hold up ��
