Apparently next time I will order the plugs when I get ahold of terminal nuts before replacement time.  _________________ 1996 K1100LT, 73K (bought at 61K on 2006)

Because each coil on a 75 only fires ONE plug... 3 coils (for assymetrical timing), 3 plugs.
4cyl engines use the "wasted spark", so one coil always fires 2 plugs.
(Useless info or what?) |

I understand that. I still don't get why a K75 would need a different plug lead with the resistive gap. Then again I'm no ignition expert. _________________ 93 LT (x2)

The Magnecor wires I just bought also came with plug caps... _________________ Bob T.
