When I first started messing with small engines I was told by shops and riders that NGK is the only brand to use . Years later when I had a Honda CR125 I would have to clean the plug with carb spray , scrub the electrode with sandpaper folded over and regap every 3 months or so . A trail buddy told me about the iridium and synthetic 2t oil as I used cheap junk . So I went to a MC shop and bought one along with Bel Ray MC1 2T oil . First thing I noticed the electrode was much smaller in size . It fired right up and I never had a oil fouled no start or fizzle like I would get since I premixed heavy . The synthetic 2T only smokes at start up where weedeater stuff left a com trail .

I used Bosch Platinum in my Honda cars along with Bosch wires as AutoZone wires sucked and they worked great . A buddy tried the Bosch Platinum in his Camaro and it was not as good as before . So we got some GMDelco standard plugs and darned it they worked better .

I have the same NGK iridium in my Echarm before I left the dealership and it has over 16k miles on it and starts up instantly .

Iridium is a semiconductor which means it has less resistance than a conductor like copper and it also has better flow of electricity . If you notice the video and others the standard plug the arc flows around where the iridium keeps the same arc flow . An iridium will not wake up a sleeping monster in your scooter , but it will start , run better and outlast a standard type

There are no spark plugs that increase engine performance, if thats what you're after.

b : the manner in which a mechanism performs.

a : efficient operation
b (1) : effective operation as measured by a comparison of production with cost (as in energy, time, and money) (2) :

Sparkplug gap alone can raise or lower your engine's MPG. I don't see how that doesn't correlate to engine efficiency/performance.

With this example shows that iridium plugs cause some change in mpg.

"Iridium metal is employed when high corrosion resistance at high temperatures is needed, as in high-end spark plugs, crucibles for recrystallization of semiconductors at high temperatures, and electrodes for the production of chlorine in the chloralkali process." Wikipedia

Here we see that the physical properties of iridium are indeed different from the standard applications of copper and other metals in a spark plug.

This is the spark pattern:

And finally, here's some propaganda from an iridium sparkplug manufacturer that shows the difference in fuel consumption:

www.globaldenso.com/en/products/aftermarket/plug/qa/iridium/images/p14-2.gif

Conclusion:
Spark plug gap plays a significant role in the spark pattern.
Spark plug spark pattern has an effect on MPG, even if it is minute.
The characteristics of spark plugs range; copper, platinum, iridium, silver, etc.
The characteristic of a sparkplug's spark thus changes.

Thus, the economical efficiency of a vehicle is not wholly dependant on, but is indeed effected by your spark plug and spark plug gap. Therefore; sparkplugs effect performance.

Ok....As long as your spark plug is functioning properly you're not going to be able to tell any difference between different types of plug. If its matched to the vehicle and gapped properly its going to do its job. There have been many number of spark plugs come out on the market claiming to increase performance. The only people who believe they actually do are the people that wasted their money on them. Its almost akin to the magnets you stick on your fuel line that magically increase fuel efficiency. Have you ever heard a real hot rodder or engine builder talk about spark plugs? I know a lot and I haven't. Because whether its made of copper, platinum, or iridium its going to do the same thing. One may outlast the other but thats it.

As to the gentleman you quoted getting better mpg after changing to iridium plugs that you point to as proof... If I poured something in my tank, bolted something onto my engine that was claimed to get better mpg, chances are I'm going to. I can drive tomorrow and get an increase of 2-3 mpg if I want to, by changing my style of driving. And if my mind is looking for mpg because of the magic I just did to my vehicle, my mind is going to give it to me, by paying more attention to how I drive. Car manufacturers have been sued because the real world fuel efficiency of their vehicle didn't live up to what was claimed. If a simple spark plug could fix the problem, then why wouldn't they do it? Don't say its cost. Auto manufactures are under pressure to meet CAFE standards, re-engineering vehicle and vehicle lineups to do so. Why do you think Chrysler and Fiat teamed up? To bring a more fuel efficient vehicle to their lineup to offset their gas guzzlers. If they could pop an iridium plug into all their engines to see an increase in 2-3 mpg, you don't think they would do it? They don't because it doesn't work.

There are spark plugs that create a 'sonic boom' that would disrupt gasoline bubbles in the vapor, causing them to become smaller. I don't know if it works, but some websites are keen on proving it does. In actuality I don't think anyone is going to see any change from chaning spark plug type neither. You could put a golden spark plug in there, and still ride just the same.
Perhaps if there are milli seconds of difference, on the tracks it would make sense, but for ordinary bikes, it'd make more sense to re-set your carburetor's AF ratio every day, and make sure the tires are pumped, than any other mods.

It is easier to initiate a spark from a smaller tip surface

I wouldn't say that's true.
It's easier to initiate a spark when the arm and tip are closer together, but with a wide center pin, the spark can form anywhere on the surface of the center pin. With a tiny center pin, there's a lot more heat that the pin has to endure (which is why they chose irridium), and the spark is more focused.

Besides, if you look at it in slow-mo, there's not one, but several sparks that appear every time the plug ignites. It goes so fast, we barely can see it, but it are several sparks, that cause ignition.
When you lengthen the gap, the bike needs more power to overcome to create a spark, and there will be fewer energy releases (or sparks) seen in slow mo.
When you shorten the space between arm and center pin, the spark will be smaller, but more sparks will be fired in that millisecond.
It's actually healthier for the bike to have a small spark plug gap, than a big one.

But like with anything, there's a middle road you'll have to figure out what works best for your bike.
On my taotao ATM50, no question, a 0.012" gap is optimal!
I set that same gap for my 150cc, and it works fine.

Ug. ^^ This post is so, so very filled with inane, nonsensical misinformation, I wouldn't know where to start. Do you just make this stuff up as you go? :-X

Please consider a little research before posting authoritatively, Prodigit!
