The infamous loosening gearbox grub screw. Refrain from riding it until it's tightened, as you can be unable to select gears. Gryph should chime in on the joys of remedying it.

Yup, your grub screw is getting loose. It's a good reason to to do a complete driveline lube and clutch service. It's about a two-three day job, but gets a lot of otherwise time consuming jobs out of the way in one fell swoop.
Here's a list of things you can do along with that damn screw to make the job really worthwhile:
-Lube final drive and driveshaft splines
-Replace rear brake pads
-Service the starter brushes
-Service the alternator monkey nutz.
-Replace the rear main seal
-Replace the clutch o-ring
-Lube the clutch splines
-Check the clutch
-Clean and service the gear position switch
-Lube the swing arm bearings
-Clean and lube the center and side stands
-Service the clutch pushrod and drive shaft boots
-Service the clutch arm and cable
-Clean, anti-seize and torque everything from the engine back
-Service or replace the rear master cylinder and brake lines
-and a good inspection and detailing of the rear half of the bike.
These are all jobs that are very easy to do when the rear of the bike is disassembled and the transmission removed. Get all those jobs out of the way now and except for the drive shaft splines, you won't have to screw around in there for at least 4-5 years.
