sorry, I forgot, your ugly and so is your mother.    and just by reading the last two weeks you should have known that if you want to talk about spark theory and burn rates, you should have asked about firstgear jackets.   duh.

Dude... chill... I was just asking a question with the hope of an engaging intelligent discourse.  

Guess this is the wrong forum for that.

(p.s. never did get a response to the rate of burn question.  I was expecting the coversation to turn to the physics and chemistry of fuel burn, hot vs. cold air intake and engine cooling methods... water vs. air vs. oil, and the pros/cons of large engine temperature variation and optimal operating temps.  Moot now, I give up.  You win.    )

OK I did answer that ... The detonation comment ...
But Lemme put it this way ... 99% of the chamber volume is the head, valves, cylinder wall etc ... 1% is the sparkplug ... heat from the plug has no consequence really ... it sparks and that's what really matters, and faster burn isn't that good ... it may detonate. Slow burn may be incomplete at high rpm, but usually mix burns fast enough to let you redline even if its slow ... BTW make it over rich ... and it wont burn at all and that causes your power loss ...
And no phaedrus we (I) dont oppose the new idea's with negativity ... atleast not where GS stuff is concerned ... But I have done some research and very much know what will work in those situations ... I do oppose the status quo - NGK sparkies are one biggie related to this really.
And davipu's analogy about 100watt bulb is incorrect too ... OK here is the reasons ... Higher wattage bulbs are lower resistance not higher, a plug with a more larger resistor wont make a hotter spark, it will if anythign kill the power of the spark, a spark plug has infinite resistance really, its open, a resistor in the plug wire helps keep radio interference down if you have a radio off the electrical system of your bike ... and doesn't do anythign for spark. A better and more powerful spark is going to need a larger plug gap, and to back that up you'd need to fit a higher voltage ignition coil, one which is capable of making enough voltage to jump the larger gap. So you cant just spend $1.50 and have more spark at your disposal. You can however get a plug that cleans itself well by virtue of retaining more temperature.
Cool.

hibbidy hoopla.  next your going to say that champion plugs run better... :mrgreen:

Uh, the only ignition advancer that's available anymore already is the poor man's version.  Send your stock one with a $5 bill to Bob Broussard and he'll make you one.
