    gp 1200 jetting

    I have a 98 gp1200 that over the winter I'm adding a 150psi head and aftermarket flame arrestors. I'm wondering if I'll need to re-jet the carbs and if anyone know what size jets I should go with I'm at sea level.

    You could run stock jetting but will need to turn your high speed adjuster's out.Sock jets are 135 main 100-95-97.5 pilot
