Should I be carrying extra spark plugs for the (2018) P1000? My Honda ATV is very sensitive when it comes to spark plugs, but these must be a different type of plug based on the price - $18.92 ea. I carry a lot of tools, jack, jumper cables, etc., but no extra spark plugs. The plug # is NGK 31909-HL4-003 I believe I was reviewing my tool bags and noticed I had no extra plugs. I guess I should definitely add them to my tool bag.
