Hey Guys, My 2002 mmax is running lean this year, she will idle fine and go at anything over 1/2 throttle fine. but when idling if i blip the throttle she will lean backfire, or if im driving partial throttle low speed i have to pull on the choke and she's fine. I checked for vacuum leaks and ruled that out, I have cleaned the carbs , tank, and fuel pump (carbs 3 diff times) and she's still the same way, i then decided to pull the vforceIII reeds and found i can see light down between most of the reed petals and the cage, could this cause this problem? i don't have the stock reeds anymore to test......
