Once again, the gap?

I want to double check the gap on my new plugs just to make sure they're where it should be before changing out my plugs along with my new 10mm Screaming Eagle plug wires.

spark plug gap

Do the spark plugs need to be gapped if so what is the gap?
Asked by: greekgod71
You should check the gap and adjust it if needed before installation. Your Owners manual will list the proper gap for your spark plugs in the specifications. Owners manuals are available for download from harley-davidson.com, choose Owners from the home page (top right) then Owners Manuals.
