I know this topic has been brought up a lot but there’s never a solid answer, so I have a 2006 trx450er with the HRC and a white brothers carbon exhaust and currently I’m running no air box lid, 178 main, 45 pilot, 75 idle, 55 leak jet, 2 1/2 turns out on A/F and I’m about 1000ft in elevation. I am having deceleration popping and it’s only at the bottom of the gear I tryed adjusting my A/F and at four turns out it only piped once or twice. I know anywhere from 3 out or more based of what I’ve read is that I need to go up on the pilot so I put a 48 pilot and the popping basically went away but when I turn the quad on there is a loud pop every time and it cranks a little more before it starts. It started up almost instantly with the 45 pilot. What is the cause I’m very confused?
