Question about resistor plugs...

[Guest]

OK, so i'm not all that up on electronic stuff.

I'm using green Dyna coils with copper Dyna wires... do i need to use resistor spark plugs, or can I use the non-resistor as well?

I don't have any electronics on the bike (radio, GPS, etc...)

Thanks

From NGK's web site:
"Q: When should I use a resistor spark plug?

A: NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.
NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.
They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.
In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion."

That is their official stance. (Clearly blood-sucking lawyers are involved.) Personally, I would not use a resistor plug unless you want to listen to an MP3 player whilst you ride.

Thanks KK, just wanted to be sure...
