Trouble is, even in your scenario below, there are too many variables..........

The "swing" on gas mileage is 10 to 20 MPG.....

not for me. As I've posted a few times here and there, when I'm doing just my standard commute run, I get a pretty standard 55/56mpg every time.
It's 99% freeway. Something like a total of 10 lights/stop signs total, to cover 20 miles. So I know this sort of accuracy is possible.
The point is, to measure it over exactly the same run.

I would agree with you, that 2mpg isnt much. I'd be more worried about what it might be doing to the engine.
5mpg more, and I'd be all over it, even though that's technically "only" 5% difference.

I know everyone is skeptical about the "miracle potions", but I would think that the amount of people on here relating that they noticed a difference should account for something.  As for the testing, i will swap mine out when i get them and take note of the mileage at fill ups just like I do with it now.  Most of the time I get 47-48 MPG during the hot weather, as of lately I am getting 50-51 MPG since the temp has cooled.  I am shocked at the MPG's that some get out of their GS's on here! 

Adidasguy, when you posted that you got to really give them a test and recorded 66 MPG, had you taken that route before with the old plugs?, And if so, what kind of mileage were you logging then?

BTW, mine are ordered and waiting to be shipped

Used to be a little over 60 on similar riding.

When plugs were swapped, I had Iridium plugs in for just a couple months. So I was swapping out pretty fresh plugs. I had noticed little difference from stock plugs to iridium ones. Noticeable difference from iridium to Brisk.

Can you define "more responsive" in some objective terms?

0-60 times faster?   0-30?  0-10?

Are you telling me that my throttle is "unresponsive"?

I would gladly do the blind taste test with you......think you can really tell the difference?

To hell with the mpg.  I ordered the plugs and replaced them in my 08 and I can feel and hear a difference immediately.  The throttle is much more responsive.  Thanks Addidas

Such testing should be done with brand new stock plugs vs. brand new brisk plugs as well to level the playing field.

Iridium plugs are not designed for carburetted engines, because just a tiny overflow can permanently damage 'em.

Maybe your bike wasn't happy with them in the first place, hence the Brisk ones feel so much better?

Just a thought.




They're way over my sparkplug budget anyway.
For the price of 4 Brisks (+shipping and customs) I can buy 20-25 Densos, which is more than enough for my lifetime, nevermind the bike.

Huh?
Where is that written?
"Overflow" of what?

I guess I better tell my Suzuki dealers to stop selling iridium plugs.

Sorry, english is not my native language, so...

What I meant was, if the bike runs rich, or the carbs "spit" a bit more gas than usual (cutting the throttle in high rpms, etc...), Iridium plugs (by Denso) tend to burn out permanently.

I've witnessed a couple of such cases (the center electrode just dissappeared from plug), so I never installed them, just the "normal" Denso plugs.

We don't use Denso that I can think of.
We use NGK Iridium plugs most of the time.
It seems many companies make Iridium plugs.
Denso says their Iridium plugs are good for 30k miles in a car as opposed to 120k miles for standard plugs. They also say they will soon be making them for motorcycles. their web page is dated 2012.

Different market, different products, I suppose. We have both Denso standard and Iridium here, and the NGKs are so low in quality recently, everyone is avoiding them.

I'd love to test those Brisks, just for smoother engine running, but does that justify the price?
Could you upload a video or a sound recording perhaps?

I'm not interested in HP gain (I got more than enough), or gas mileage (15-39 sprockets are pretty economical combo for me).

Of course....scientific method.....

Another thought..supposedly the Brisk plugs derive their "magic" do to more complete or "more efficient" fuel burn.....i.e. same fuel,  but more burned = more power, smoother etc...

If this is so...wouldn't a simple emissions test show the whole story?

Incomplete fuel burn shows up as hydrocarbons in exhaust (I think).......

So ...   Have the emissions checked..then switch plugs and have 'em rechecked..see what the difference in exhaust gasses results...

Come on guys...I grasping for anything, anything objective...give me something!

You are right that a better burn of what's there is the difference. I also find it is a more consistent burn as shown by smoother running of the engine.
Mashing on the throttle I don't get that momentary lag. Acceleration takes off in a smooth curve.

if there wasn't a difference in spark plugs, wouldn't we all be using el-cheap-o Champions or wally-mark plugs? Why would we use NGK? The why go iridium?

Its OK if you don't think the high price of Brisk plugs are worth the change in performance. However I think anyone who questions that one plug is better than another should be forced to use the cheapest plug around since they don't think plugs make a difference.

Once yo say "I won't use that cheap brand of plug" or "I prefer iridiums" you have admitted you believe plugs do make a difference. Now it is justifying the added expense of Brisk .vs. the performance.

I'll try a riding video - I have a long steep hill where I can mash the throttle - with different plugs. Far enough from my house that when I get there the engine will always be the same temperature.

After 45 years of riding,40 of which have also been offroad I have tried most every brand of plug, here what I have learned!!.
In 2strokes autolite plugs ALWAYS fouled within 30 minutes or so ( from 125cc-500cc ).Champions would SOMETIMES last a full weekend.NGK's were by far the best,I could go for a whole year on the same plug!!.In my street going 4 strokes I never had many problems with Champions but I never felt like I was getting everything out of the bike with them.Autolites always fouled in 2 of my bikes,my 550 seca and my 700 virago bobber.I can honestly say I have never,ever had a problem with NGK's in my street bikes and in a 2stroke I changed them every year just to start new but I would carry the old plug as a spare.Now I have Trey and he has the brisk plugs and he runs great,starts with little or no choke and seems to get good mpg.I have never ridden a GS500 with NGK's so I can't compare them.When we head to Deadhorse next June I will be bringing EXTRA plugs for both bikes and they will be NGK's!!.

HUH?    Suzuki specifies either Denso or NGK....both common and available.

Iridium really doesn't make sense to me in that engine.

You are equating price to performance........

First of all, you have to define "performance"    then you have to figure out a way to measure it...then you have to run tests to compare......

For instance fuel economy would be one parameter of Performance....but getting 66 MPH on a single ride, without any comparison to anything else just does not show anything.........

Performance parameters such as "smoothness" are certainly hard to define, and even harder to measure........"throttle response" is another purely subjective parameter.........

My bike has never experienced any discernible "lag" of any type, using stock plugs....I have also never experienced any "lack of throttle response".   So I would not even begin to know what I am missing!

My bike also seems to get exactly the same MPH as you, but with stock plugs...so where's the benefit?

How about this?  When you do that video...make many runs...and change from the Brisk plugs to Regular NGK and back again...several times...BUT....    have an assistant choose and change the plugs, so you do not know which are installed...  mix them up....two runs with the same...then change.. then don't change etc....A" blind taste test".....see if you can "name the plugs"...say 10 out of 10 runs....Then I would see some objective information as to the improvement offered by these plugs.......

Only problem I see, is I don't like to remove plugs when the engine is full hot....

Of course if I were doing a definitive test....It would require many more runs, over varied terrain...longer distances...at different temperatures etc.  Also I would throw in a set of really cheap ass plugs, and maybe even a defective plug...just to keep the rider honest!

But hey.....I do appreciate your input so far....really....better to let you do the hard work, and me to watch!

science aside... i've noticed that the people that have tried the brisk plug report that they notice a difference (un-qualified of course) .... and those that haven't actually tried them , have every reason known to history why they wont work and cant work ...

I dont think Brisk would market them as having some advantage if they didnt have some advantage... like the renthal people wouldnt market their bars as better .. or pirelli their tyres ... or Smuckers their peanut butter!

demanding scientific evaluation might better be aimed at the company rather than the user.. the company might actually have done some previous testing or something! 

if anyone is happy with real/perceived performance gains for the $ spent then  .. its all good... getting one's knickers in a twist over lack of quantifiable data just because it goes against one's viewpoint is just stress for no reason... someone wants justified data .. let them spend their time/money ...

anyone who is already happy with any change ... whether real/magic/imagined/holy intervention .. then they can be happy.

kinda easy really ...

oh and this being a discussion forum and not a Licensed Testing Authority laboratory ... viewpoints can and of course will differ. 

Thank you Janx.

I started the thread because I found some spark plugs which I felt really improved the performance of my bikes. My neighbors also noticed they sounded better, quieter and ran smoother.

I'm not here to sell anyone on them.

I just reported that I found a good product.

I don't need to do any comparison tests. I'm not here to sell them to you. I'm not here to convince you they are better than what you have.

I like Shorai batteries. If you like Wallymart - that's OK.

If you like Champion or K-Mart plugs, that's OK.

This being the internet, people can take a discussion to ad-nauseum just to be arguing with no real purpose in mind.

I am delighted with Brisk plugs. Make up your own mind. Try them or don't try them.

Thank you again Janx for saying what needed to be said.

Everything else you were saying made since, but this, you need to be a more discerning consumer about :-}

There are PLENTY of businesses, whose revenue is based *solely* on their ability to market to gullible people.
Pure marketing. Not any actual advantage, or even benefit of the product At All.

Not saying brisk is one of those companies. Just saying your premise there is invalid.

I am not a gullible person and never have been and I am happy to say the plugs have made a world of difference to the running of both my bikes
I am so happy that adidasguy mentioned them here and cannot thank him enough

Looks like the only way to settle this is to get a GS, some normal plugs, iridium plugs, and some brisk plugs, a camera, and a dyno.
