Hello all, I stumbled onto this by accident and wondered if anyone here has tried it.  Basically, you remove the resistor in a spark plug and replace it with a piece of copper wire.  I thought this was an interesting idea mainly because non resistor plugs are not locally available for me.  Here’s a link to the procedure by one guy.  There are a couple others, but all seem to use the same principle.
Thanks,

One wonders why a guy who is trying to impress the world would not "proofread" his video set-up, making sure the viewers could see his hands, his saucer, and everything that, in this video, happens off-camera. Not saying his idea doesn't work. Just that it's a little less convincing when you can't see a thing he's doing.
Except burning his head with his torch.

the topic is interesting, I will probably try this at some point
and because this is a "nice guy" forum I won't say that I was hoping to see him set his bushy brows on fire

Zero resistance he says, expect for the plug gap which has many, many thousands of ohms resistance.  This seems like a bad idea, unless the objective is to take a perfectly good spark plug and make it far less reliable.

I would rather ditch the resistor cap and run a resistor plug if I were determined to minimize resistance in the high tension path.  On the other hand, I've had no problems running resistor caps and resistor plugs on many two strokes and most modern two strokes come that way from the factory.

I agree that this mod is likely to reduce reliability...

The claim of losing over 2 times the spark energy is BS...  and spark energy is flea power.  The only thing that matters is having a system that reliably ignites the air/fuel mixture.  No horsepower or efficiency can be gained by a better or more powerful spark than that!
Adding resistance to an old system...  like by running a resistor plug and a resistor cap... will reduce the spark voltage of what is an already marginal voltage in the 15,000 to 20,000 volt range.  (If I remember correctly it takes around a minimum of 10,000 volts to jump a 0.020" spark gap under pressure).  Really not a good idea on those systems as you start getting close to the point of unreliable ignition.

In comparison, modern systems are likely to have more voltage than God's own lightning so the extra resistance is not a big a deal and can actually help ignition by extending the duration of the spark a few milliseconds.

The engineers design the system with a certain amount of resistance in mind.  Best practice is to stick with what resistance they originally designed.... especially on older systems.  As non-resistor plugs seem to be getting phased out, I'd swap to a non-resistor plug cap or remove the resistor from the plug cap before I started messing with trying to remove a resistor from a spark plug.
