If it has had recent work done on the front end ie the forks resprung 2 weeks ago i would check and make sure everything that was disturbed whilst that work was carried out is still ok.
Chances are something could have been over looked or loosened itself in those 2 weeks if it had been disturbed before. Defo check everything rather then assuming head bearings it may well be a simple tightening something up fix that will save you the cost of having/getting new head bearings fitted.
or it may just be the headbearings
