Farkling unbelievable spark plugs!

[gsJack]

1. Higher HP and torque by up to 3 %
2. increased economy by up to 5%
3. 360° Firing Technology
4. Improved acceleration by up to 15 %
5. 25,000 miles - 40,000 km duration

That's about 1 more HP at best.  I change standard plugs at 6-7k miles and notice the difference in performance.  With 95k miles on my 02 GS now I notice even more improvement in performance after a 2-3k mile oil change.  Sounds like a value equal to a Suzuki oem air fillter bought at list price.  Hope the duration claim holds up and you get the 25k miles out of them, at about $2.5 per DPR8EA9 the value might be nearly equal.

if the contest would have been for zip ties I would have bit earlier. wire is too much trouble.

(you paid too much for plugs)

[noiseguy]

The newer automotive plugs (in watercooled engines, anyway) last a lot longer than the old style plugs.

I replaced my Chev Impala's plugs at 100K. The original AC Delco Iridium plugs I pulled out looked the same as the new AC Delco Iridium plugs I put in... I think they could have gone another 100K if not for the risk of them galling into the head. Plugs cost about 4X as much as the cheapys, but I figure it's also good for another 100K... that's 4-6 fewer times I need to work on the plugs. Win.

I'll be skeptical until I come over and see/feel/hear it for myself. I'll keep an open mind, but there is only so much a spark plug can do.

This morning I wanted to see how well they work. as you mentioned it was warm yesterday, this morning it was 55 so that would be a good test.

Started with no choke or throttle. It did die out after about 30 seconds. So I started again with just a little blip of the throttle. No choke. Idled fine at 1100. In 30 seconds it went up to 1400 idling. Rode off to work. No choke. Ran better than he ever did with iridium  plugs and the choke.

I'm convinced they work better.

Working on the video now.

[stokes776]

Cant wait to see the video on them.  The way you speak about them makes me want to buy a set!

[CrownSeven]

Put in an order for a set.  We shall see if Adidas is smoking crack or not 

Also ordered a set of the Bullet Vis running lights.  Been wanting a set for a while now.

Ouch very unhappy about my local zuki dealer then as I payed 20 a plug and 'apparently' they only come in 4 packs so am left with two spares. . . Yay wish I had of known about these lol

There's a reason some call them stealerships. Now then, some are better than others, and the same one can be reasonable on one part and rip you off on another. But it's always best to have some idea of what you are dealing with before you walk in there, so you can choose to walk right back out if they want you to bend over and drop your pants...

Case in recent point - I now have 25 each of the pilot screw o-ring and the top cover o-ring in Viton, which set me back $6 and $3, respectively. Not only was the local dealer out of them (and 4 days to get from suzuki) but they want $3+ each. McMaster sent them in 2 days - if UPS hadn't goofed, would have been one. There were some other things in the order, so I can't say exactly what the shipping for just those would have been, but they are very small and light - along with some heavy stuff it was $5 or so shipping. If anybody had been willing to measure a set that wasn't shot, I could have had the whole set of carb o-rings (not the float gasket, which is a Suzuki-only or at least Mikuni-only part) 25 times over for about the price of one or two each at the dealership. Which is why I measured the new ones as carefully as possible and posted those measurements in my thread and the carb sticky thread for the next guy...

I may have some teeny tiny o-rings for sale when I feel like I have time to be a "responsive seller"  - and they won't be $3 each.

Just to keep Adidasguy truly happy - you could have bought some at wally-mart for, like, $2 each ;^)

Anyone care to try to explain where the benefits may be coming from? Dyno comparison would be perfect but I don't see that happening any time soon.

The Brisk site has performance data. Also a video showing the difference in the spark.

MY VIDEO
Showing me starting up Phenix this morning with no choke at 55 degrees. I didn't know if he would start without choke or not. He did. never has started before without the choke. He always needed choke and a minute of warm up.

Woohooo second view  (im assuming you were the first) great video, but walmart is still cheaper 

i may have to get some

[kml.krk]

nice! I am impressed.
If I was still commuting on a bike I would actually get those! I can't wait to read more testimonies.
PS. I don't care for increased HP much but any help with starting, especially in winter, is greatly appreciated here

Well, it was a full day of twisties. 160 miles in all. My mileage in Phenix was about 5% better than I ever had: 62 mpg.

One problem I find in a group doung twisties that affects my mileage is the huge 1300's like Harleys and Yamahas. Their engines have better engine braking so in the turns and twisties they can just let off the throttle. I often have to do a little braking then hit the throttle again to keep a proper distance behind them. I think that cost me a couple mpg. Not complaining - I had a fantastic ride today. Smallest bike on the ride today was a Yamaha 200 dual sport. There was a cool Honda CBR-250.

What I noticed most in comparing Phenix now with him before, and the other 3 GS500's was performance.

When going 60 or so and hitting the throttle, it accelerated. There was no momentary hesitation or any feel of sluggishness. Yes - it is a 500 and won't pop a wheelie. But on a sudden twist of the throttle, it was smooth with no perceptible drop in power all across 3000-8000 rpm (I don't know if I went over 8k - I happened to see 8k at one time.)

Overall power band seemed smoother with no drops or hesitation or sluggishness.

I'd say overall I am quite impressed and pleased with these plugs. Perhaps the better spark results in much better combustion resulting in the improved performance.

When I get the rest in, I will do some video of before and after as a comparison. I know it can be hard to understand the difference. We all know our bikes and how they run. Each bike has a personality and characteristics to how it performs. That's how I can tell the difference.

FYI: Phenix has a 2006 engine with stock carbs and in need of valve adjustment and the carbs probably could use a good cleaning as the PO was not good at maintenance and admitted that (motor from a 2006 bike bought for parts due to farkled up title making it untitleable).

If only Wally-mart carried them everyone would be happy (right iclrag?)

[scrichton]

I'm taking a leap of faith too.

Look what I found on fleabay

Lots has been said about Brisk plugs over the years in various bike and car forums but this is the comment that sticks in my mind the most.

We, Brisk, don't claim any specific value increase of HP rating. What you have seen on the link, is an independent stockist/supplier, marketing the spark plugs with their own HP claims, and this has nothing to do with Brisk.

From here: http://www.gixxer.com/forums/showthread.php?t=278645

Makes you wonder what else could have been ` made up` and whats fact and whats fiction 

I guess if you perceive an improvement with these plugs and are prepared to accommodate the extra cost and reduced lifespan that goes with them then go for it, afterall its your cash. I am quite happy with the way my bikes start/run/tickover using  traditional style OEM plugs. If they were good enough for Suzuki when the GS5 was designed they are good enough for me now and I doubt the average rider would even notice 1 or 2 extra hp on a well maintained GS5. My mpg figures are always a variable depending on conditions and choice, afterall I ride for kicks not for economy and I can see +/- 15 mpg. I am not going to pay extra for something that supposedly increases gives a slight increase in economy when it is of no concern to me.

BTW brisk are not the only ones who make surface discharge plugs, just about all the major manufacturers have their own take on the design strange thing is they dont seem to have caught on. The biggest question of all though is.........if all these gains can be made just by fitting a particular sparkplug why aren't the manufacturers doing it on the assembly lines??

[The Buddha]

These plugs obviously shoot the spark into un obstructed compressed mix. The rest of the plugs in the world have the hook electrode in front and the arc is to that electrode. My thought is that these wont last as long as the old style ones. They obviously have some way of making that occur, and I suspect it may give up sometime long before the regular ones do.
Cool.

cost

Brisk plugs cost 4-5 times the price of traditional plugs because people are prepared to pay 4-5 times the price than traditional plugs.

Suzuki will be buying thousands and thousands of sparkplugs at a time, manufacturers want to sell them thousands and thousands at a time, because it is a far more cost efficient way of doing it for both parties.....economies of scale etc. The discounts will be huge and the actual difference in `factory gate` cost per unit between the two types, assuming THERE IS actually one would be insignificant when you consider the potential gains and increased market appeal the `improved` bike would have.
