This could be an early sign that one carb is slightly leaner than the others.

While it is running acceptably now, this could be a sign that that carb is about to burn that cyl/piston without even an overheat alarm warning.

Lay all the plugs out in good light (sunlight) and take a few hi res pics and post them here.

It wouldn't hurt to clean your carbs and pay very close attention to the float levels
