81 gs650, coil wires, resistor question?

[Crazy_Russian]

ive replaced the spark plug wires on the 650, the wires came from Z1 with a regular rubber boots on them (the old boots are shot, that's why i didn't reuse them), the spark plugs are not resistor plugs (no R on NGK plug) should i get an NGK plug with a resistor in it? or can i run it just like it is?

[Crazy_Russian]

anyone? help plz, im not to familiar with the ignition system on these bikes

Remove caps/boots from coil wires- wire to wire should have a resisitance of about 12k ohm. Put caps/boots back on, resistance should now be about 31k ohms between them. Just use NGK D8EA plug, it's cheap. So you attached new Z1 wires into your original coils?

You are not required to run resistor plugs or boots. It will be just fine without them.
Hey, my post count is 5555. Hehe.

Tom, yes i did, fairly easy process :-)
Koolaid, thank you:-) congrats

now head another question after thinking about this for a while. whats the deal with the resistor plugs and resistor spark plug caps? im trying to understand this system a little bit more...
thanks guys :-)

Resistor plugs suppress radio interference from the spark plugs. If you don't have a radio in a fairing on the bike you should be OK>

[koolaid_kid]

However, if you do have a tube-type AM radio tuned to your favorite station broadcasting Rush Limbaugh, you will have issues.
Not with the suppression, of course, but with the fact that you are listening to Rush...

I've also found having NPR on the radio leads to issues. Not with the bike but issues of another sort.

hey, whats wrong with Rush? ive watched them live a few years ago when they were here in town
so other then radio interference it wont cause any problems, cool thank you guys!
