I never used the iridiums I do however like tinkering with the gap I found for my bike at.038 the bike pings a little less but will gurgle a little more on decel but at .035 it will ping alot when it gets hot. The fuel probably has more to do with it but bye and large .038 works best for me go figure |

Eric, if you knew as much as you think you do, then you'd know that picture is of a plug for a ford modular v8. The plug goes deep into the head and the heat shield has been known to seize and break off upon removal. That's why you see anti-seize past the threads.
I find it better to let people think i'm a dick, than to keep typing and remove all doubt. I have no doubt about you sir. |

So, all the posturing aside, blah, blah blah, does anybody use that extreme spark type plug?
Never sure about dealing with companies that can't spell motorcycle, not usually a good sign.
Their other designs look interesting but their bike one uses the old recessed electrode style which history has already passed by.
How about the pulse plug at about $35 a pop?

I've posted a thread about those Pulstar's before and came to the conclusion there crap. I've used the NGKi's before and like them plus after my own research I think they're a good choice for me. So just confirming, there is or is not a need to gap the Iridium plugs from American Sport Bike? |

I'll vouch for the Extreme spark plugs. That is the company that bought the Torque Master brand which was made by a SoCal inventor in El Segundo, California before Bosch started producing similar products. I've been running the same amazing TM plugs in my 3 Buells: '03 Firebolt for 52k miles, '98 S3 for 38.5k mi. and in the '96 S1 for 47k miles.
Of significance to this thread is that 1) they don't foul, 2) the (equivalent) gap, at 0.120" inch is non-adjustable, 3) the resistor is sized to produce a hot spark yet provide long electrode life because of the 360 degree firing pattern.
Of course they are more expensive than conventional spark plugs but, hey, if they'll last 200k miles in an ordinary car, they should last the same in my bike, right? Well, I'm on my way to find out.  I'll keep ya posted when I reach the first 100k milestone. |

This much is for sure...there is a lot of BS and ignorance about spark plugs...toss in all those gimmicky double throw down super trick multi gap blah, blah designs.
It'll make you head spin...and you stand a good chance of making the engine run worse or damaging it..stick with what the engineers decided the motor needs.
Here is the skinny on irridium...it is used because it is tough and heat resistant...that is the reason they last so long...either way if the physical design is wrong and/or the heat range is wrong....you are in trouble.
I used to run the "standard" NGK (at $1.35 each...less on sale) plugs in my "metric" dragbike...with no ignition problems at 11K+ rpm AND nitrous...I have Denso irridiums in my Buell...should outlast the motor... |
