    79 GS750e sparkplug caps ("x" type, "s" type?)

    With the winter tear down on my bike already started, I'm in the process of replacing the failing sparkplug wires and caps.
    I don't normally build wires, so when looking for caps, I have no idea what NGK X type of NGK S type mean.
    Any input or info on what resistive caps to get or look for?
    Are there better or alternative brands I should look at or consider?

    Thank you. Found the ones I need I think.
    Want to confirm the resistance (bike is in my shop ~100km from home). It has MARTEK coils on it, but I can't find any markings in the photos other than 1-81 which comes up with nothing in a search. Can't even locate a similar coil in Google.20160924_144933.jpg

      Be careful to only use NGK resistor type caps if you are using copper core non resistor wires. You don't want to use resistor caps with suppressor type wires because then you will be doubling up in the resistance so to speak.

      To measure is to know.

        That is the plan. Copper wire with resistor caps.
        Ordered new 7mm wire already, just need to confirm the cap resistance for those MARTEK coils.
        Guess I may have to hit the shop and measure all four wires and caps on the bike to find if it's still 5k caps

          New wire and caps came in. Need to work on the wiring harness with new wire and connectors, but all looks good so far. The NGK caps are much nicer than the aftermarket ones that were falling apart.

          Picture doesn't do them justice.
