My quad is brand new (1week) and I just removed my lid and the quad bogs a lot. The stock plug is black(rich) and when I change it to a DPR8Z it stays ''silver''(lean)... I've turn my fuel mixture screw few turns out, in... and my quad bogs when I'm at idle and I press to WOT(in neutral). I just want to know if I should reput my mix screw to 2.5 turns out and buy a 155 main or anything else. ALL IMPUTS WILL BE GREATLY APPRECIATED :)

Thanks a lot

And how did you turn the mix screw??? with ur fingers or you turn the carb by loosing the intake boots screws?

i would make sure the skrew is 2.75-3 turns out with an open air box lid and a stock pilot jet. i would try a 152 keihin main for starters.

try to avoid revving it to full throttle in neutral. it is tough on engines.
