your problem can be a sign of a need for a valve adjustment or replacement depending on history .
checking valve clearance is considered normal maintainance on the four strokes.

Agreed. If you've never had any maintenance done over the life of the bike, it might be time for at minimum a valve adjustment or at most a new top end depending on how many hours are on the bike.
