No need for anything fancy.
Plain non resistor is fine especially if you have resistor leads or caps.
Never run more than one source of resistance if any..Mikuni Viton Choke Plunger Seat Renewal.

As above, stock was resistors in the caps, none in the plugs. The exotic electrode plugs are more resistant to spark erosion, so wear slower and keep their sharp electrode edges longer. They don't add power, just deteriorate a slower rate. Makes sense for long service interval cars. Worth the extra money in a GS? Probably not.

The resistor can be removed from the plug caps, and replaced with a chunk of solid core copper wire. That will allow running resistor spark plugs. Just an option...Ed

NGK discontinued B8ES (2411) plugs a few years back. They'll sell you the BR8ES (5422) resistor plugs as the replacement. These are externally identical and will screw in and work, but they are resistor plugs, not the correct non-resistor plugs.
The listings for the B8ES on scAmazon and fleaBay are for counterfeits; spark plugs are some of the most widely counterfeited items on the planet. Only order and install spark plugs from reputable automotive suppliers. Napa and a few other places list the NGK 2411 as available to order, but they will substitute the BR8ES/5422.
The Denso (ND) W24ES-U (4030) was also factory correct on the same GS models and seems to be available off and on. Right now they're on RockAuto for $1.42 each, so you might want to grab a few sets.
As Ed states, one resistor in the ignition at a time is enough. If you need to use resistor plugs, then use non-resistor wires and caps, or convert your caps.Last edited by bwringer; 09-16-2024, 07:36 PM.1983 GS850G, Cosmos Blue.

I buy them in boxes of 10.
Very easy to spot a fake and ebay always sides with the buyer if you happen to receive any and returns are free if the item is not as described so no big risk buying from there.
Lack of the part number on the hex flat and loose sealing washers are the main giveaway for NGK fakes but i've never had any yet.....
