in my experience it was because
1/ the spark plugs were dirty ( i clean the plugs on almost every ride)
2/ the plug gap was incorrect - this stopped the problem - the preset gap was too wide.
3/ Exhaust leak if on deceleration
4/ Timing incorrect (if thru carb)
5/ incorrect valve adjustment
6/ intake valve not seated
