Thanks to Paul from the VTXOA for this list
My "X" plugs were DENSO from the factory and look like this.....
Bosch 4418 Platinum +4 plugs with about 1,000 miles on them. Note that two plugs are relatively clean on
the electrode while two are not. This is due to the "waste" fire system which fires one postitvely and one
negatively. Unfortunately, these plugs came to me un-indexed so there is no way to tell which plug
was where on the bike so we cannot determine which was "clean" and which was "dirty."
