Farkling unbelievable spark plugs!

[Janx101]

Maybe they're out because of a sudden run on them for us GS500 people?
I've ordered 10 plugs (5 sets) for my bikes (and Trey, not mine now) and a spare set. All came in a few days, but that was before everybody started ordering them.

PLUG HOG!!!!  ... you are a one man plug shortage there Adidas!! .. dont go blamin the collective 'us GS500'

I found them - I got first dibs! 

4 sets went to the 4 GS500's. One of the spares went to bluesmudge's CT-110

neener neener neener - I ain't a hoardin' dem sparkies! I'm just a makin' me bikez runz better.

[Janx101]

yeah i get it!.. you're not only a plug hog but a gloating plug hog!! 

and .. should the new designation of the CT110 ... be CT111 ?! ... now it has all the extra go! .. 

[Formori]

He didn't take them all, cause I got mine today!

Adidasguy, I have to say, biggest and most noticeable difference from a single performance upgrade part I've ever bought!!!

I did a test to prove to myself if these actually made a difference (since I was a little skeptical) and I tried to start my bike from cold in the garage (ambient ~24 degrees) (Celsius for those Americans ) it tried, sputtered and then promptly died. I tried this 3 times without choke. Then I started the bike with a little throttle and let it sit for a moment.

After doing other things around the house, and removing the fairing and fixing a crack in one of the mounts, I replaced the plugs and from cold again tried to start it... It started without hesitation and ran smoothly without choke or throttle

I then took her for a quick ride around the block, and it is noticeable smoother and WAY more torquey! Throttle mashing is fun now!

We have only had Trey for 2 days and it's only been getting down to the mid 50's,but every cold start has been with no choke !!.I'm a believer !!!.

I've read enough to try these bad boys out. Within the next month!

Hey adidas, have you got your neighbor to try these plugs?

[Phil B]

on the whole choke/no choke thing.. can a gearhead attempt to explain WHY a regular type sparkplug benefits from choke at cold start, but these ones get by?
What is heating up and getting happier? holes for the fuel to come through,  expanding?

[Formori]

A choke on a carburated engine is there to "richen" the air/fuel mix for startup, since when an engine is cold the fuel doesn''t atomize well and this creates an incomplete burn in the cylinder, so the engine runs rough or doesn't stay going.

If you use a choke, it'll richen the mix and also raise the throttle a hair, to help warm the engine before you put it in gear and put strain on it, which, if not warmed can cause problems in the engine as the oil isn't warm enough to circulate fully, and running lean burns hotter than it's supposed to.

These plugs have a much larger spark gap and are also deeper in the combustion chamber, providing a much better burn in the cylinder, even when not under ideal conditions (mix, temp, carb fouling, etc). They just burn the fuel better, and that allows them to keep the engine going even when it's cold, and at a lower rev also means it'll warm the engine more evenly and produce less thermal stress on the internals, making everything run more smoothly!!!

This is just what I understand, did I miss anything?

You beat me to it!
from what i understand though, they are not technically deeper in the chamber, as they extend to where the end of a normal sparkplug is at, however the way they spark (mushroom shaped) goes deeper into the chamber as it isnt between metal vertically so it sparks out of the plug instead of on the inside of it

that's all i have to add

[NortwestRider]

Just to clear this up alittle,just because I don't need the choke to start the bike it still takes alittle time to warm up enough to ride off.What happens is this, start the bike and let it idle for maybe 1-2 minutes while you get your helmet on.Then give it some throttle till it takes it,let idle again and your good to go.

On regular spark plugs, the spark can only go in one place: that tiny gap. If fuel is not there, you mis-fire.

With the Brisk plug, the spark can go anywhere in the 360* circle. A spark will follow the path of least resistance. Rather than poorly atomized fuel having to get in that tiny gap on a standard plug, it can be anywhere in the vicinity of the Brisk electrode. That will result in a firing of the cylinder even if the fuel is poorly atomized. As long as there is fuel somewhere near that electrode, the spark has an infinite number of paths to take in the full 360* circle.

The insulator has, in addition to the standard electrode, 2 rings of titanium which act as a passive electrode. The spark can jump from main electrode to the passive then from somewhere around the circle jump again. With no many paths the spark can take, it will result in a good burn every time.

Unlike a standard plug which must have fuel in that little gap. Then the standard electrode acts as a shield preventing the combustion  from going in every direction. Cumbustion must go around the electrode, which will slow the burn. The brisk plugs have nothing to block the combustion. It will mushroom out in all directions unimpeded by the standard type electrode.

[Formori]

Something I just thought of to add to Adidasguy's post, that people would file the electrode of the spark plug round so that fuel/air mix could get in and out of the spark's path easier, but it reduced the life of the spark plug.

(As far as I know, people still do this but it's not recommended as it can reduce the plugs effectiveness if done wrong )

And riding to work this morning was amazing! No choke cold start, low-idling warmup and very smooth rpm's all the way to work! Thanks Adidasguy for posting about these!

Interesting.
Has anyone played with a brisk plug, in the plug wire out side of the engine?
Ok that sounded wierd. I mean like if you were testing a plug, to see what the spark looks like.

Lol, I played with my plugs last night when I was installing them!   

The spark pattern is random around the head (or so it looked) and didn't favor any point on the ground, and it sorta mushroom's a bit. The sparks are a lot longer than a normal plug, and looked brighter, but it's pretty cool nonetheless.

If I setup my camera right I might be able to get a photo of it.

[GI_JO_NATHAN]

Huh.
Kinda makes you wonder why the gap is so imprtant for every different vehicle with normal plugs.

From a nice post at
http://www.teamswift.net/viewtopic.php?f=11&t=7183

Plug gaps were critical back in the days of Charles Kettering - too large a gap and there was insufficient voltage to jump it, no spark occured and the engine misfired, too small a gap and the resulting spark was too small to ignite the mixture and again the engine misfired - we had to clean, file (to ensure square edges - easier to get a good spark) and gap the plugs about every three months to prevent misfiring, and also maintain the breaker points, keep them clean, filed, gap adjusted correctly (this affected the ignition timing more than anything else) and smear a little grease on the cam to prevent the heel of the breaker points from wearing too rapidly.

...
Modern automobiles, and that includes these fifteen year old cars, all come with breakerless electronic ignitions, lots of spark voltage, and they'll fire the plug almost without regard for it's condition

MIght try

[jestercinti]

I give up.  Time to order the epic plugs.

I just flipped over 9100 miles and it's starting to stall when I release the throttle when pulling up to a stoplight.  I've been busy keeping my company out of trouble (I'm an auditor) and being the president of a local auditing organization (ISACA) that I totally forgot about my valves 

Looks like I will order the plugs and some shims very soon.

[yamahonkawazuki]

We're sorry. This item can't be shipped to your selected destination. You may either change the shipping address or delete the item from your order. 

Google  "br12ZC". You'll probably get a dealer there.

Or try Magnum Tuning's site directly (I posted the link)

Or try www.brisk.com

Or go to www.brisk.eu

or have em sent to adidas, and he can send to you. or send to me, and i can do likewise. ive been here since 2003 i can be trusted, as can adidasguy
