ok so on this molkt carb on my gpx 150, blip the trottle and hold it, and it bogs till the engine dies. i have a 105 main jet and a 25 pilot jet needle 2nd notch from top. could the pilot be too rich. should i try the pilot that came in the carb or is it going to be too lean and cause damage. i have the mikuni on the way but sunday is a track day and i would love to ride.
