    02 GP1200R Possible Carb Problem, Bogging/Dying at low RPM/MPH HELP

    Recently bought a 02 GP1200r used with about 100 hours on it. The ski has a D plate and chip and has good compression on all 3 cylinders first off. The problem I am having is when it is cold it is hard to start and also has severe bogging hesitation in the water only at low rpms and speeds. Once I warm it up and gte it over 30 mph or so it nevermisses a beat and I can hit low 60 mph on it. If I let the ski sit on the shore for 20 mins or so it goes right back to having a bog hesitation at low rpms. the plugs were also replaced at the start of the year and I am running pre mix 40:1 oil in it. What do you think the problem is on it? If you think it is a carb problem, how hard is it to get to the carbs and rebuild them? A local shop wanted $650 out to door to do all 3 with parts and labor. Thanks in advance.

    I am thinking you are going to have to rejet, those skis are already seriously lean on the pilot circuit premixing the ski leans it even further.
    Y'all know me, still the same O.G. but I been low-key
    hated on by most these &^$$@s with no cheese, no deals and no G's, no wheels and no keys, no boats, no snowmobiles, and no skis, mad at me cause I can finally afford to provide my family with groceries

    I was 300SXing when 300SXing wasn't cool !
