Farkling unbelievable spark plugs!

[Formori]

I don't think there would be a significantly higher loading effect on the coils since the overall change in voltage (say, 1cm is 10KV, so go from ~3mm gap to ~1cm gap, voltage goes from 3kv to 10kv) has negligible change in current draw from the distributor (stator in bikes?).

That makes plenty of sense, I was just wondering, having seen videos and things involving coil overheat and failure due to massive electrode plug usage that overloads the coil.


if you read the product specs:

On the surface of the spark plug insulator (between the center electrode and spark plug shell (ground) is a conductive titanium oxide compound in the shape of rings, bonded by a special patented process. Because these rings are conductive, the rings act as a "short cut" for the spark discharge on the way to ground.

Spark "travels" from the center electrode to the edge of the first conductive ring, uses the ring as a conductor, jumps out from the other edge of the first ring intot he edge of the second conductive ring, uses it as a conductor, and then the spark discharge "jumps out" into the spark plug shell (ground) to complete the secondary ignition circuit.

So, they've basically extended the ceramic insulator, and given the current a leap-frog path back to ground.

its perty interestin i think.

Hmmm, I've never seen that, but I'd definitely like to know more about how that's supposed to work (or fail, whichever).

From a little reading, I think the brisk plugs just use a larger inductor coil to jump the voltage coming in (like most plugs do) and the missing tab above it means there's nothing to get in the way of the spark to air/fuel mix, making it more efficient (and the longer spark helps too).

I've just ordered myself a set of these, and she's been a little jumpy starting off lately, so I'll see how they work compared to NGK stockers and let you know!

Not saying I was skeptical before or anything, but you guys have me wanting to give them a shot now.

What's awesome is that a few months ago my wife would prolly give me crap for spending an excesive amount on something like that. But now that she's the one mostly riding the bike, it's ok. lol
Now I get dirty looks for spending money on the dual sport. lol

Since I and others do feel an improvement in performance, I'm seeing about a dyno run.
Some places around here have free dyno days for our local club members. I'm checking if I can do a double run with iridium and Brisk plugs. Maybe include standard plugs if they let me.

now you're talkin!


make sure your iridium plugs are brand new too, post up the runs!

Curious, I have done only a little reading about spark plugs, but are these just unbox and install, or do you have to do anything to adjust/set them for the bike.

I was reading about gapping spark plugs.

I will research that if I need to, but was wondering if you guys just plugged them in and they started working.

[jestercinti]

no gap neeed.  Just unbox and install.  See pictures in this thread an it will make sense.

These arent normal spark plugs, they dont need to be gapped (although i think most plugs now adays come pre-gapped) because they spark in a mushroom shape

[codajastal]

Spark plugs turned up today so I will let you guys know if there is a difference. At the moment I have iridium plugs in there.

UPDATE

Well I took out the iridium plugs and installed the Brisk ones and started the bike as per normal (No choke (it doesnt work) and a little throttle to warm up (I have a throttle lock)

I usually have to keep the throttle on about 2.5k till I start riding off or until bike is really warmed up before I can let go of the throttle and then it usually idles rough until I have ridden up the road.

Well WOW it took about a minute at 1.5k to warm then it idled perfectly without any assistance. This has never happened before. The bike actually sounded much better than the other bike which was very strange to me as it never has. I cannot wait to go for a ride and see if the performance changes.

I will be getting some more to put into the other bike which already runs and starts fine to see what happens there.
So far I am very impressed

If you think about it, that means that the brisk plugs are making your engine cylinders burn hotter.
All. The. Time.
The only way your engine warms up to standard running temp, faster, without changing the capacity of the engine, is to increase the temp in the heating element, so to speak.


I leave it to more mechanically astute people, to speak on what ramifications that may have for the engine, long term.

For my own non-adept viewpoint, this suggests to me that people using the racing plugs, may want to somehow increase the engine cooling factor. But I have no idea how to do that, or how important that may be.

[Janx101]

hmmm.. after thinking a short while on this ... i beleive the solution may lie with more high speed riding in the evenings when the air is cooler .. more cooling airflow with naturally cooler air! .... wow my powers of logical extrapolation are absolutely humming today!

Ok maybe I should not have used the word WARM as it obviously means something different to me than to you.
I do not mean warm as in HOT I mean as in time it takes the bike to idle properly without having to blip the throttle. The bike is not running any hotter at all or getting hotter sooner, It is however running better at a sooner rate than it did before.
Here in Beautiful Australia on the east coast of Queensland we do not have to WARM our bikes as you yanks seem to?
Hope that clears that up?

it does seem though as while warming is not so prevalent here in Aussie.... the time honoured Roasting of tyres is frequently taken up.. why just the other day i was relaxing in front of the TV and saw what i can only describe as a mini festival in honor of tyre roasting!... the participants would roast their tyres till the desired smoke level was reached then ride off down these weird parallel pathways after the judges signalled them with a victory flash of a odd looking metal "xmas tree" ?! .. i assume the short ride and subsequent return past the admiring crowd was to acknowledge the 'job well done' uluations in appreciation for the aforementioned Roasting Display.

also.. i noted that the best roasters were often invited back a short time later for a 'roast off' to determine the ultimate smokemeister!

they also mentioned a trap was around somewhere.... i have to assume that it is only activated for those participants whose roasting abilities left much to be desired ... they said it was at the end of the pathways .. which makes sense i guess as a victory lap should not be allowed to complete if the judges deem the smoke level unworthy...

The engine isn't actually running hotter, it's just burning the fuel more efficiently and since it can now (with the new plugs) ignite better the engine temperature doesn't need to be as high for smooth running, so it doesn't need the choke to warm like it did before.

To run hot like you're describing means you're running lean and not getting complete combustion, and so your carbs need to be adjusted.

With the wide temperature and humidity spans we've been having here lately, I can't wait to try these new plugs!

Hmm.  yeah, that could be another explanation.

But on the other hand, "burning fuel more efficiently", can often mean "gets more energy out of the fuel per unit".
Which usually results in "more heat per fuel unit".

Might be interesting if someone could actually use some kind of thermal probe and measure.

not to change subject, but your avatar is pretty good 

[GI_JO_NATHAN]

Ok so..ordered mine today!

[codajastal]

Well I took a ride around the block on the red GS. Only about 2kms/1.5miles? and just in that short distance I am so farking impressed with these plugs. Better response, absolutely no balking or flat spots and the bike seems faster? Cant wait for the other ones to turn up so I can fit them into the black GS. (took it round the block too and wanted to get off and go back to the red one).

[slipperymongoose]

I can't believe those plugs are for real.

[codajastal]

Oh they are definitely for real slips. You know I would not say they were if they were sh!t cause I tell it like it is.
