Im trying to order the BRISK sparks...but havent decided yet..if I do, I will test it on my dyno table with varios of ignition timing...If they produce overall 360 degree spark then I think it will be a difference...But how long they last dont know...for racing I would change it 2 times per season...

One more thing is, because of the 360 degree cap it will be hard to read the spark,especially ignition timing, fuel to air I think no problem, temperature of spark also under ??...so will see...will report it...

I was looking at them the other day, for the price they better produce something...

You're near-stock, it makes no sense to dick around with different plugs. The amount of money you're dumping into this bike with minor mods is going to end up costing you the same as something like head and cams

Basic thermo dynamics, better combustion,u get a better bang for the bike = more power
Im.getting a spare engine that i will mod.the.head and use my moded tb,also will do some mods to.the inyector layout...still working on my cad design to make place for it

Were there any objective facts in this thread? Sorry I missed it.
Keep on experimenting on your dime, and hit us with some objective facts.

But now, there is another- the force is strong in this one!

That is assuming that the spark plug is delivering insufficient spark to detonate the fuel. You can change the spark plug heat range up or down based on your application, but that's still going to net you negligible horsepower. Same thing for spark plug gap, which you can vary until you find the gap that gives you the most power. Once you've reached that peak, you can also find higher voltage coils, which will allow you to run a larger gap, but that will also only net you with very minor gains.

He could also drill holes in his airbox. Also, to be objective, it would have to be a test that is repeatable on standardized equipment. Yet, we all know that even with SAE standardization, not all dynos read the same.

I've built drag motors, street motors and track motors.
"There is no replacing displacement."
If you want real gains, larger bore, high compression, cams, head work and dyno tune.

Many are satisfied with milling the head .10-20 thousandths of an inch, and a nice set of cams degreed to proper specs and a dyno tune. I've seen 7 HP with milling the head alone on an R1.

Unless you increase the air flow through the engine creating a need for more fuel, you are limited to your gains.

The only time high performance coils are needed is if you have a lack of spark, We've run turbo Hyabusas upwards of 250 HP with stock coils and NGK plugs. I'm an avid user and supporter of NGK plugs.
I'm all for tinkering, so carry on. Just dont go backwards in your quest.
