Halo spark plugs

Some R 1100 RT rider suggested surging would be better or stopped after using the Halo spark plugs see

http://www.haloplug.com/
not a great site for a new product maybe they are better in technics as promotional?

The technical explanation seems ok.

On a Belgium forum some riders reported a significant better riding of no progress?

For the S, only the big sparks would be available.

Someone have some experience?

Snake oil if you ask me. If the plugs in the bike are able to make a spark and ignite the explosive mixture of petrol and air in the cylinder, then how can a different plug make any difference?

Maybe it is possible the ignition time is quicker because of the shorter
way the spark has to make?

It seems only some riders from Belgium have tried it with some better results,
also a R11S TwinSp rider said he would try to change the main spark plug but no response till now.

I launched the question on several other R11 forums till now any reply.

A new plug from Brisk

The site above has evidence to support it makes the larger engines in US autos better. As for BMW twins?

There is one advantage, that some on here may welcome

:-

The Halo’s gap is preset at the factory and, unlike standard spark plugs, never needs to be adjusted. The gap remains constant to ensure optimum combustion and maximum engine performance.

Except that it is a physical impossibility. Whenever a spark fires, material from both electrodes gets removed. You can slow it down by using different materials, but never stop. Unless they have found a magical means of adding material.

Don't think so. Electricity travels at the speed of light and nothing can go any faster. If it did work then you could get the same by advancing the ignition timing.

Any manufacturer is going to post a few favorable comments on their website but they will never post the comments from people who thing that the do nothing.
The spark will always jump to the nearest part of the outer electrode and so the gap will not be uniform all the way around after a few miles.

That is exactly my thought! The Brisk boasts that it offers a 360 degree spark, between centre and edge. That may be the case if the plug is prepared to nano precision, but I suspect it will soon deteriorate to a normal, single arc to the nearest point.
Plugs have clearly improved from the old Champion N9 that would burn away rapidly with leaded and oil fouled petrol. As I have mentioned before, unleaded petrol and new plug technology allows plugs to last 20 000 miles in normal engines. High performance demands more frequent changes, to the degree where race engines are aged by the hours of use.
I suspect almost any new plug will give 'better' performance when first installed. Brisk type plugs may allow a slightly better flame growth as there is no electrode shadowing the initial spark. It will need a dyno test to prove it.

Race engines run on mileage not hours,as for plugs!!bet the most i've ever done on a plug is 3000 miles and even then,it's like chalk and cheese putting a new set in,last time i ever checked a gap on a plug must have been late seventies when in the those days a new plug didn't mean it was going to be any good.

3,000 miles the longest you do with a plug? I leave mine in for 12,000 miles and they come out looking just fine.

The f650 forum had a debate on the use of plugs to get rid of surging. Debate after debate after debate. The point made there was not a different plug material but a slightly longer (more protruding) electrode.... apparently hitting a "hot spot" in the combustion mass. Sounds like a lot of bollocks to me, perhaps just a poor excuse for not mapping the engine well enough. But hey... I'm no expert

I've seen plugs that have done 20,000 mile and looked fine,the ran crap.
