Hello guys, I've noticed on my way to work there is a long stretch of dual carriageway leading to junction 10 towards Walsall and I've noticed that I'm doing 60-70 mph and when I let off the throttle it sounds like the exhaust pops! Can anyone explain this???? Thanks!   
Probly a crack or little hole in exhaust causing it to back fire my old vx runner did it all time dont worry bout it
It's just backfiring, nothing to worry about, everyone seems flails their arms around panicking for some reason when they find out their bike backfires.
