Anyone here on this forum try any of these Brisk Spark Plugs, they state they out perform any others on the maket and help increase mileage and power. They make them for the Kawasaki 1700 models.

Here is what they state;

If you need aggressive ignition performance and spark voltage at unparalleled levels don't miss the chance to purchase Brisk Bike performance spark plugs. Misfires are now controlled and these plugs will allow you to have steadily high levels of improved acceleration and throttle response. Thanks to Brisk's commitment in innovation and its 25-year experience in plug manufacturing, misfires and non-firing issues have been abolished for good and all, consequently combustion conditions have improved dramatically, resulting in increased engine performance. These heavy duty plugs are designed to help Buyers improve HP, torque, kickout time and acceleration furthermore to increase fuel efficiency. Our racing plugs' design ensures optimum mix ignition in the cylinders and warrants extra HP, compared to standard projective tip plugs or other brand performance plugs. 360-degree electrode plugs outperform even iridium spark plugs in regards to firing energy, extra power as well as durability.

Never heard of them, but honestly, as long as your current plugs are firing everytime, I cant see plugs making a noticable difference i performance. If you have a high performance ignition with higher voltage, a different electrode metal may last longer due to not burning out as quick.

I have often wonder how companies can sell these products that will "Improve" you performance. A spark plug, is a spark plug, is a spark plug. Get a reputable brand that manufactures a quality products that will withstand the heat of your ignition and go. This is my opinion and opinion only. But all of these "performance enhancing" spark plugs are just marketing gimmicks. 1 ground electrode, 2 ground electrodes, or 1 big one that is a complete circle around the center electrode, you still get one nice blue spark and it will travel the path of least resistance.

A spark plug does one job:
It creates a flame kernel in the compressed air/fuel mixture.
The flame kernel travels (propagates) across the combustion chamber in the form of a controlled burn.

It never ceases to amaze me how much useless crap is marketed, and how steadily the public gobbles it up.

BTW -- Nobody in business for a slight 25 years makes their own spark plugs. A steel foundry, ceramic foundry, and several hydraulic presses/crimpers are necessary. A very high capital investment for a niche product.

Run what came in the bike and you can't go wrong.

Anyone want some snake oil? Anyone?

The plugs that come in the 1700 have a good reputation for reliability. I don't see a reason to experiment with something that isn't having a problem, and perhaps introduce a problem that I didn't have!

Here is some of my experience with plugs.
First, there IS A DIFFERENCE in plugs and it pertains to the how and where in their operation.
HUH?
As has been said, the plug is the final conduit for the voltage generated in the coil. The gap is the exposed part of that conduit. The "quality" of that gap, where the gap sits in the combustion chamber, how that gap affects the voltage of the spark and the quality and size of that initial ball of flame that starts the combustion process will have an influence on the affectiveness of that plug.

I had a GSXR1000 in the shop a few years back that had headwork, milled head and a set of cams. The work was done by a popular race shop for sportbikes. During the dyno work here at my shop we pulled the plugs to inspect them. We found a set of Brisk plugs. I had never heard of them and was very interested in them as they were very different from what I had seen before. I am guessing they could be classified as a "surface discharge plug" as they had no ground electrode. This is the "how" the plug design affects the spark quality.The spark had to jump from the center electrode to the base of the plug, and that distance was at least .100", quite large. A gap this large would have the affect in raising the voltage required to jump that gap but also shortening the duration of that spark.
Now the "where" aspect. Since the spark must jump "back" to the base of the plug, that initial ball of flame is now starting on the side of the plug. That flame front now has the protruding spark plug in it's path somewhat blocking it's path across the combustion chamber. Such a large path for the spark would suggest a HUGE ball of flame and good and complete combustion.
The plugs were clean and in good shape, but as my curiosity of thier performance grew I decided to install the plugs we use in the GSXR's for a back to back comparison. The plugs we use are platinum tipped dual ground electrode plugs. NGK brand. The dyno runs were less than one hour apart and the results were impressive.
The NGK plugs started to show a power gain at 5000 rpm. There were gains of 2.6 hp @ 7000, 3.4hp @ 8000 and 9000 rpm, 2.9 @ 10,000rpm with a 1.3 hp gain at the peak! The brisk plugs wre no match. I have also seen no gains in performance with E3 plugs when compared to the plugs I sell.

Bottom line, where the plug gap sits in the combustion chamber, how much of the air/fuel mixture is exposed to the gap and how little the plug "blocks" the flame front from spreading across and thru the combustion chamber is all important. The 1700's use an "extremely projected tip" Iridium plug that is one of the best designs available and I have dyno results and customer feedback documenting that fact.

Iridium is a very hard metal so electrode wear is minimal as compared to a copper or platinum center electrode plug. These plugs can probably last 50,000 miles!

Wow, impressive write up. I am not arguing your theory at all when I say this as I do not have the education or experience of you. But in our (average Joe) day to day lives, I do not believe a 1 hp change would make me smile any bigger or smaller while cruising on the V2K. Even though I know I need a good clean complete burn of fuel in the combustion chamber. So I will stick to the NGK _____ plugs that my service manual calls for.

EDIT: Sorry I misread your last post. I reread it after I replied. I thought you said the Brisk Plugs showed improvement over the NGK. My Bad.

Were these the plugs you pulled out of the zook. I have never understood how companies claim multiple sparks with only one center electrode. Doesn't electricity follow the path of least resistance and will still form one spark to the closest/cleanest part of the base of the plug???

That plug looks like what we pulled out, but that this comparison was done back in April 2007. Whether it was the same I do not know.

Brisk is claiming mutiple simultaneous sparks, how that is accomplished I don't know. Lighting tha a/f mixture at 3 different points with the resulting 3 flame fronts would improve combustion efficiency and could be beneficial for performance. Engines with more than one plug per cylinder benefit from better combustion due to "lighting the fire" in different areas of the chamber.

The power improvements on the dyno are the results of increases in torque and that is one of the things you WILL feel. In this example there will also be an improvement in mpg, an increase in engine smoothness and improved throttle response. Positive dyno results will translate into real world performance gains.

... if it dose what is say it dose... I like being knowledgeable in what products are available but sometimes it is hard to tell what is truth and what is advertisement fluff. And this is something that I (on my own) can test one way or the other.

The only way to get multiple sparks is to re-saturate the ignition coil primary winding, collapse it, and repeat in succession. No spark plug can do this. The Law of Conservation of Energy tells us the spark will jump the gap with only the voltage required to close the circuit back to ground. If a plug gap requires 8kv to arc, and the factory coil is rated for 50kv, putting in a 100kv coil is of absolutely no benefit to anyone except the guy selling the 100kv coil.

If you want multiple sparks, buy a MSD. You won't see any benefit unless the engine and induction system are highly modified..

Ray, thanks for the detailed explanations that you posted here on how Plugs really work and what you have found out over the many years of experience in your motorcycle shop.

Will keep using these factory installed plugs in my Vaquero for sure.

Thru the years I have found that increasing the spark voltage does indeed provide benefits to performance, and one way that happens is in being able to inrease the plug gap from lets say .032" to .045" and up to .050". The higher voltage can and will jump the larger gap without high rpm misfiring.
That bigger gap provides for more of the a/f mixture to be exposed to the spark, thus a bigger initial ball of flame.

I have used MSD systems for many years. Thet are multiple spark discharge only up to a certain rpm at which the electronice just cannot charge the capacitors fast enuff. The biggest advantage to something like the MSD or the DYNA CDI is in the hotter (higher voltage) spark. Installing a Dyna CDI on skoots has an immediate improvement in performance even at stock plug gaps!

Yea, their claim to simultaneous multiple sparks is quite far fetched!!

THANK YOU SIR...but this thread has me thinking, again. Quite some time ago I looked into installing a set of Dyna coils, but they are so much larger than the stockers it would take some ,uh, inventiveness to fit them.
The stock plug gap is larger than most other skoots at .039" to .043". To me that indicates ignition coils with a healthy output.

The Brisk documentation states multiple simultaneous sparks, not multiple consecutive sparks.
Reminds me when the GM HEI ignition system first came out. They were recommending gaps in the .060" range, but after a couple of years, they backed that specification down to the .040" to .045" range.
