Hi all
Does anybody know what causes the rev to not drop as quick as they should? When I blip the throttle it’s sometimes slow to come back down to idle !
Any help would be much appreciated.(1979z1000st)

Possibly cracked rubbers between carbs and head. Is the throttle snapping shut all the way.

Blocked pilot jets are typical. I always drain my carbs after every run as I never know when I'm going out next on the bike. Ethanol, say no more.
