Spark plug read

That may explain my disdain for looking into rear-view mirrors. There is only a disorienting red flash...and a resonating whew!

Your setup would necessitate using resistor caps...correct? :kiss:

I don't know?! It seems like no resistance doesn't matter but even in this thread there's confusion. I'm going to run the copper wires and b8es (no resistance) and see what happens.

I respect your opinions, and highly enjoy looking at the visual aids employed when making your points.

My bike has a Dynatek 2000, put in a couple years ago along with a pair of Dyna Mini-coils. I specifically inquired with Dynatek (Larry N.) about going with solid-core wires, and he suggested there should be no related problems created by doing the setup that way.

Also, I did that hundred-mile ride today, and when done, there was no apparent difference in plug appearance from the picture above.

The Dyna 2000 listing at Z1 Enterprises includes a recommendation of Dyna suppression (resistor type) spark plug wires, and includes a link to the Dyna 2000 installation instructions.

Here is an excerpt from the instructions:




According to the reported advice received from Larry N. at Dynatek, the resistance provided by the R plugs in the secondary loop is an acceptable substitute to sufficiently replace the resistance provided by suppressor spark plug wires.

It follows that the Dyna 2000 is included among the delicate electronics that could be adversely affected by lack of a resistance component. However, such is not the case with other less sophisticated bike ignitions such as stock points, Dyna-S, and stock Igniter, which perform perfectly without any resistor component whatever in the secondary loop.

Good Fortune!

An thinking another option for solid core wires with non-R plugs would be fitting appropriate resistor style plug caps, whereby standard NGKB8ES spark plugs could be used.

The standard plugs are sometimes more readily available. In a pinch, traveling cross-country and needing a new plug, would rather be needing a standard plug.

Good Fortune!

Thanks Patton, I couldn't say it better. After all of this, I'm still confused that Dynatek would not state the same in their literature (unless the sale of resistor plug wires is a primary consideration), but left it for me to determine.

NGK says their "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.

NGK produces caps -- "covers" -- with various ohm resistance specs:

Including the 5 ohm version:

I haven't yet found the ohm resistance specs for the Dyna suppression wires in order to compare the wire's resistance with the 5k ohm resistance in each R spark plug.

Perhaps someone could measure the ohm resistance in a new Dyna suppression spark plug wire, and let us know.
The wire's resistance will presumably be in the neighborhood of 5k ohm (which would match the 5k ohm resistance in an R plug), but will probably vary with length of the wire.

It would be interesting to know whether (1) the measured resistance in the secondary loop between non-resistor caps on suppression wires, matches (2) the measured resistance in the secondary loop between R plug tips in non-resistor caps on solid core wires.

Good Fortune!

Am learning that the ohms resistance is measured "by the foot" in suppressor type spark plug wires, whereby a longer length will offer more resistance.

Suppression plug wires are available in two types, being graphite core (such as Dyna) or spiral core plug wires (such as offered by NGK).

Spiral core wires use a magnetic field to reduce electrical interference, and are lower resistance than graphite core to provide more spark.

However, the ohms resistance in a foot of suppressor plug wire (either type) may significantly differ from the 5k ohms in an R plug. Per the above link, suppression plug wire typically has a resistance of 3,000 to 20,000 ohms/ft. depending on the manufacturer.

Good Fortune!
