The plugs in the new four strokes last for a long time. The electronic ignition systems along with the better materials being used in the plugs keep the plugs from eating themselves.
I have had customers with the same plug in their engines for over a year.
When you take your plug out, inspect the electrode. It should be sharp on the edges. If the edges of the electrode look rough or burnt, replace the plug.
