i have a 34pj carb main needle # is R1470n set in the middle. i have tryed the piolet jets 38,40,42,45,55,58 lean to rich and i cant get it to idel with the turn knob adjuster. my main is a 155 witch i know is close and i know that i shouldnt be any lower than a 48 piolet jet. i am just looking to see if mabe i have the wrong needle size in my carb or what the deal mabe? the bike has a vitos 240 kit with a b1 pipe no port work, so any needle and piolet info or some thing i may try before i off the carb. i have cleaned the carb and have tryed the air screw diff times and i am ganna try a 50 tomarrow thanks
