It is interesting when a couple say spark plugs have no effect on performance, power or mileage.

While we have read of 2 people with the same problem, I believe it is more if an installation mistake. The top cap must be unscrewed. Then the Brisk use a 16mm wrench rather than 18mm. If you don't have a 16mm you won't get them correctly installed. (Most wrench sets seem to omit 16 and 18mm sizes). These couple of people didn't have a poorer running bike - they basically had a dead bike. That points to installation issues as mentioned.

Many of those that tout spark plugs make no difference do seem to feel iridium plugs are better. They also have a preference of what brand to use. That invalidates any argument of spark plugs not making any difference.

Then we have the issue of gapping. Our stock plugs are pre-gapped. Someone asked recently in some other thread about gapping plugs. The gap makes a difference in the spark. If properly gapping a plug is important, then it means the length, duration and power of the spark are important.

Brisk plugs have a different shape to the spark. Therefore, if gap is important then a different, more open and powerful spark should be better.

Except for maybe 2 people, all with the Brisk plugs have found some improvement and probably more than half of us have been very happy with the change in performance. I seem to think the two significant changes are smoother running and no lag when going WOT (smooth acceleration without that momentary drop in power)

For those that say plugs make no difference I ask:
1. What brand and type of plug do you use and why?
2. If using iridium plugs, why waste your money on them when you say the plug makes do difference?
3. Why aren't you using the cheapest, crappiest plug you can find to save a few dollars since plugs make no difference?
4.Why are there high performance racing plugs? Wouldn't racers be using the cheapest plugs around since plugs make no difference?
5. Have you actually compared the Brisk plugs to what you use now?
6. If 2 people had problems and they were correctly installed, then again that invalidates the argument that plugs make no difference.
7. If plugs make no difference, why do we have choices? Why are there different types on the market from stock, iridium, platinum, multi-spark and ring fire? Wouldn't the market dictate only the cheapest plug would be bought if plugs make no difference?
8. Some plugs ARE better and better made: which is a reason the FAA has to certify a plug before it can be used in aircraft.

It is OK since it is the internet to be argumentative about Brisk plugs. It is only natural to put down something you have not tried. But look at all your reasons why you do not use the cheapest plugs around then reassess the discussion on Brisk high performance plugs.

Brisk does have dyno runs to back up their claims. Most of us using them fully agree with their claims of better power, performance and mileage. Some agree with part.

(To the two who couldn't get them working: please look again at how you installed them.)

I am no expert, but will offer my thoughts. I have used stock, iridium and the brisk, and the iridium are my preference. While I can start the brisk with no choke, i find I can ride the bike faster with a little choke and the iridium plugs. The bike won't start with choke with the brisk, so I have to give a little gas and then put the choke on so it doesn't die. I will admit, the bike sounds nicer with the brisk and seems to perform better while warm, but most of my rides are very short so start up time is important.

Adidasguy:

1. I did unscrew the caps before installation.
2. I did use the right socket to install, and made sure that they were seated properly.
3. I didn't have a dead bike right off the bat. In fact, it worked for about two months, only with decidedly longer start times, about 2 to 3 seconds of cranking, I'd say. This was eating away the battery charge in the mornings (specially cold ones)
4. I'm not really "touting" anything. I'm simply sharing my own experience with the "Farkling unbelievable spark plugs!"
5. I never indicated any preference for Iridium, or any specific brand of spark plugs. While I don't feel I was arguing anything, I don't see how my story is "invalid".
6. I would say that while there are some posts that are clearly argumentative, I don't see how mine was. I just followed a recommendation done by one of the most prominent members of this forum. It didn't work for me. I'm sharing that story. You're clearly passionate about these plugs. Cool! I'm happy that they work for you. Seriously!
7. Lastly, I did acknowledge some gains in mpg and very little in power. In my opinion, too little to justify the price and the lag at start/need to gas it a little, etc.

Didn't like them. Pulled them out. I'm happy again! I, based on my experience, would not recommend these plugs to anyone.

Thank you for clarifying that. The original brief mention of what was going on seemed like you just put them in.

What did they look like? Were they getting fouled? Indications of running lean or rich?

Let's see what happens with the other plugs in. I wonder if there is something that is fouling the plugs. We'll again see in a few months of riding?

Can you post a picture of them so we can see if they were getting fouled and see how your bike was running? Something happening over a couple months of degrading performance might be plug fouling with time.

11 pages, and only one independant dyno run posted.

then, its discredited or replaced with "feel" and "impressions".

that's all I needed to know the $3 each plugs were right for me.

suckers. born. every. minute.

Brisk plugs are not new, they have been around for years and always make for interesting topics in the many bike forums I visit. Taking every comment I can remember into consideration I would say 50% of users swear by them and the other 50% swear at them!

Until I see the real experts ie the mainstream manufactures setting up their products specifically for, then fitting and reccomending Brisks I will Always remain sceptical and before some one suggests it the answer is no, I wont be bothering to buy and fit a set just to satisfy curiosity. I simply cant be bothered on the basis I know for a fact that even if they do live up to the hype they wont improve my enjoyment of motorcycling by one iota. However I wont dismiss them and if buying and using them is another one of those things that makes your little world even more warm and fuzzy and/or makes your bike even more special then go for it.

What is amusing though is that is seems we have reached a stage in the argument where the Brisk supporters are now trying to convince others that they dont actually have problems with them when fitted when they obviously do........and are citing otherl issues or poor fitting techniques for these problems.

if we're talking cellphones, and apple in particular, it would be "the reality distortion field" the late jobs was famous for.


since its only a spark plug, whose one and only purpose is to ignite fuel air mixtures, I dunno. I guess its too easy to point to the dyno chart and shrug instead of accept that part in the Honda, suzuki, and other owners manuals:
"using more expensive parts, fuels or oils only increases the costs of ownership."

I'd just like to chime in with a quick thought/question. I'm fairly skeptical of the spark plugs, but I love me some hard data, which seems to be lacking here.

Anyways I was thinking about it, and the larger sparking surfaces WILL cause the 'electrodes' to run cooler, potentially creating fouling issues. Also, I imagine that a larger spark, like is described in this thread, will cause more reliable ignition in lean situations. I'm thinking fuel/air ratio needs experimentation with these plugs. Stoichiometry only gives us a reasonable starting point.

The ideal test would be someone with access to a dyno testing the brisk plugs in a stock bike, then testing the same plugs in the same bike with a little bit larger jets. Something could also be done with audio analysis of the exhaust to find the smoothness of the idle or warmup period.

Next step down would be someone modifying their jetting to see how it changes how the bike runs with brisk plugs. e.x., adidasguy going up a few sizes, or someone with a rejetted bike going back to stock (leaner) and comparing the two.

Easiest and most likely to happen though, a quick poll to look for a pattern:

For those who notice a significant improvement from the plugs, are you running stock/lean jetting?
And for those who do not notice a difference, or notice a negative impact from the plugs, are you running modified jetting?

I appreciate Badot's attempt to bring this conversation back to an experimental and scientific basis as opposed to accusations.  I do know that adidasguy typically runs with the stock jets, right?  So your hypothesis might be on to something.

This plug looks very interesting but the cost has me a bit hesitant. Will searching for other info i ran across the Pulstar plug. Anybody every use these? These could be an alternative to the more expensive Brisk but have the same results...

Certified testing shows that Pulstar® pulse plugs deliver these consumer benefits:
•Greater engine torque – up to 9%
•Greater horsepower – up to 7%
•Quicker throttle response
•Better fuel economy – up to 10%
•Lower emissions – across the board reductions
•Smoother operation
•Enhanced driving experience
•Easier starting
•Improved towing capacity

Taken from their website.

The Pulstar plug is different from Brisk in that Pulstart's claim to fame is an internal capacitor.  Brisk's claim to fame is the lack of the grounding electrode... Pulstar reviews are similar to Brisk, though, in that they all seem to show mixed results, where some parameters benefit all around, some benefit only one parameter, or one parameter suffers, or paramaters suffer all around...

Well i guess it all comes down to money and what people are willing to spend on a particular item. As cost per unit/cost per mile. Thats how i see it. Worth ~$18 hmmm...i may try the Pulstar since im due for plugs anyway. Dyno results and before and after mpg results on various gs500s with "performance" plugs would ultimalty be the best thing.

I finally tried these plugs. I must say, I did notice a small improvement in the bikes ability to start in the morning which makes me happy. That alone is almost worth it.

Regarding performance, I haven't noticed much of a difference. Maybe a slightly quicker throttle response....maybe. The bike does sound a little better at idle.

Does it start better when it is really cold (sub-40*)?  Just curious to see if anyone has tried that.  My bike is a PITA below 40 (Duh...air cooled and really cold) with Iridiums...have to choke the hell out of it.  I read somewhere that gas atomization occurs at 45* or so.

There I go getting all technical again...

Well, it hasn't been much below 50 degrees Fahrenheit yet in the Seattle area, I'll let you know once the temperature drops.

If I give the bike some throttle for 5-10 seconds seconds, I don't need choke at 50 degrees. Or I give it full choke, start it up, put on my helmet and gloves and then take the choke off and ride.

This was only a small improvement from what it was. You will see the biggest improvement in cold starting by setting your exhaust valve clearances a little loser than Suzuki spec. Before my last valve check it probably took the bike 10 minutes of riding before it would idle with no choke in cold weather-- I'm never going to let it get that bad again.

Valves just adjusted, and mine were bad too. Had to go down 2 sizes.

Thanks for the info.

To ask Adidasguy, and anyone else that has/is using them, if he is still using these plugs, and what his thoughts are. I'd like to know if there's an increase in workload to the battery, to the point that it possibly drains them faster.

Been using them in all bikes. All OK. They are a little sensitive to low voltage since they have 25% higher resistance than NGK's.

I have no reason to take them out.

No extra drain on battery.

I'm still using them and still working perfectly on my Red GS. Done many many miles since install and have yet to remove them for a look as I have had no reason too,

I took them out a while ago, since I had a dying battery and found that the Iridium ones did better on start up...But since I got my Shorai LiFe battery and did a valve job and fixed my jetting, I think I'll pop them back in! Thanks for the reminder!
