Since the gap size has a direct affect on the spark plug's tip temperature
and on the voltage necessary to ionize (light) the air/fuel mixture, careful attention is required. As a rule, the more power you are making, the smaller the gap you will need. A spark plug's voltage requirement is directly proportionate to the gap size. The larger the gap, the more voltage is needed to bridge the gap. Most experienced tuners know that opening gaps up to present a larger spark to the air/fuel mixture maximizes burn efficiency. Many racers add high power ignition systems, the added power allows them to open the gap yet still provide a strong spark.

more spark IE length..... more complete burn of the fuel
I'm sure if Bear was unchained, he would prolly give you a more complete answer
Biggy D could prolly shed some lite as well

BTW, the moron that designed the clips that hold the plastics on my 450 needs to be slapped. PIA.

This used to be one of the tricks we used to squeeze the last bit out of drag engines and I have not seen mention of it in years. Were we wasting our time or is it just not worth the time and trouble?

That why you folks ask me important questions like....... what is 2 + 2 =?
should we use pitstick?

I have always indexed my plugs on my drag cars and then on my winged sprint cars and I did it on my TRX 250R as well. On stock machines I have never bother to do it, but the thought just occured to me the other day that I should be doing it on my 700R now that it's been internally modified.
