Whats your mods? Elevation. That pilot seems kinda rich. a ripped carb boot will give you that backfire to. ive spent many hours on a dyno so let me no your mods and ill help ya out

hey i have a full duncan exhaust, k&n filter with airbox cover removed, and a jetted carb. my bike pops too when i let go of the gas but i thought that would be normal right??

try turning the fuel mix. screw out and make sure exhaust is tight!

ya it started off with an exhaust leak, then still popped, tinkered with the jetting ended up going with a 50/182, and moving down the clip on the needle
