Okay I will start with the current settings 06YFZ 3000 ft GYTR slip on Box lid removed Stock filter Cam mod Dyno jet kit (all jets listed are DJ) DJ 144 main DJ pilot 48 DJ needle 5th clip AP timing and duration set to factory specs 2 turns pilot screw Heres the problem, after a few long hard full throttle pulls the bike falls flat on its face as if it were out of gas, dies, the only thing that keeps it running is the forward motion with the clutch out. theres also a popping on deceleration problem, but I assume that a lean main (correct ?) Is there a temp switch that shuts down or retards the timing when a lean condition causes the motor to over heat ? a fuel cap not venting, or a carb float thats not filling the float bowl ? It didnt do this before I started messing with the carb, so i'm pretty sure its carb related.
