What is the best way to totally disable the air cut valve? I have plugged small hole, and cut the pin on the diaphram, removed the spring. This helped, but not completely. Also thought about using silicone, could get messy! Bike is 2000 WR400 yz timed, DSP exhaust, EKN#4 MJ170,PJ42,PAS65,MAJ160,AIR SCREW 2.0 rich on bottom, lean reading on top, cr8eix. ACV seems to mess up jetting more on bottom.
