is it popping while in gear still, or are you clutching in?
whenever i’m at low RPM’s (2000 or less) and have the clutch engaged, and am just coasting…i get tons of backfires…ranging from barely noticable to gun-shot like…
it’s just fuel being dumped in the exhaust i would believe…and it’s not too uncommong for aftermarket exhausts with no cats and such…
backfire is bad when it does it while you’re on the gas…
but, if you’re still worried, check the full exhaust…and if you have the ability, check to see if you’re running rich at all…that might explain excess fuel… :gotme:
