    GP1200R was running excellent, Help??

    Well, I rode for 2 days with no issues and it ran great. Rode again today and at the end of a wavy lake ride...I headed back at full throttle on smooth water and it started cutting out at high speed after about 5 seconds. Should I come out on the high an 1/8th? I am 1 1/8 out on low and 1.5 out on highs.

    Below is my set-up:

    1.5 N/S
    95 gram spring
    110 Pilot
    125 main
    43 Pop off
    32:1 ratio
    SBT carb rebuild kits with New SBT motor
    Wave eater couplers
    Flame arrestors with choke and accelerators removed.

    Thanks

    Piston Wash is the burn pattern left on the piston..

    Top of pistons look burnt with oil. I have also attached pics of plugs from my wrist Left to Right Front, Middle, PTO.

    We have a search feature. In general you are looking for a thumb nail size wash at the ports.

    If the plugs are new,it will take a bit to get color out of them.A 'mis' sounds more like electrical.Example,a bad plug wire will cause a mis,a crack in the plug insulator will cause a mis,coil etc,....running lean will stick a piston from heat and lack fuel and oil.
