Answer
Hi Shawn.
 Was the bike running with the old plug in?  If so, then just match the plug so you know what plug fits there now and use that size in the future.

 The other option is to replace the head so that the plugs that go in are the correct ones.

 If you try to resize the plug hole down, then it will never work quite right.

Good luck.
