Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

performance spark plugs

Post by Crash- Elmit on Sat 16 Sep 2017, 3:27 pm

Whilst looking on fleabay for the decals I came across a posting for performance spark plugs that the makers claim increases hp and fuel economy, amongst other things.
anyone on here tried them or know someone that has? I'm interested in finding out the real results of using a set.

If you want to be technical yes... but all new spark plugs will.. 

Since the spark plug is new the electrode will not be worn or carboned up meaning the spark is much more stronger so it'll burn the fuel better (explains the hp claim) because of the stronger spark you won't open the throttle as hard thus saving a minute amount of fuel. 

So albeit they're not lying they've just got got a good marketing technique as all new sparkplugs will do this. Personally making sure the sparkplug gap is correct is more important but I doubt many people even bother with adjusting new plugs to the spec.

Spot on! Which is also why replacing OE plugs with Iridium ones is a good idea. They wear a good deal slower, thus maintaining correct gapping longer. Mine have done 60.000 km by now and show no signs of wear.

Performance plugs may also come with multiple gaps, If my understanding is correct. Not sure if it's possible to get more than one spark though...

Interesting.

I've tried to dig up a little more inf on the manufacturer to see if there's any substance like an R&D department to back up the claims. Here's what I found:


www.briskracing.com/


So, I searched for the part number BRBIKE-471 - see the fleabay text. This came up:



Then I did a stepwise search. It turns out there are no Honda motorcycles listed:



I'm now suspicious regarding the validity of the fleabay offering.


How about writing the Brisk people, asking them about bike-plugs?

I have used brisk flashover type plugs for a good few years now and highly reccomend them.
I don't think that top end power seemed very different but the lower and mid range seemed stronger, it could just be a mind thing or maybe because I use stick coils. Whatever plugs you use, if your coils or leads and plug caps are goosed then you're fighting a loosing battle.
Multi gap plugs don't neccesarily have two or more sparks but what they do have is a choice of paths to follow. If a conventional plug is fouled then it won't fire, and let's face it there's not a big gap to foul is there. However it takes much more to foul a multi earth plug and so less chance of a misfire.
Realistically engines in a road state of tune probably only have an efficient burn about 75-80% of the time and race engines 90-95% so that's a lot of scope for a plug to be fouled.
I have tried platinum and Iridium plugs which do last as previously stated but most still have the same problem of being single point plugs, due to the nature of the thinner electrodes cleaning up better they are more efficient than the standard plugs but in my view not as reliable as the multi earth ones.

Thanks Andy.

I use iridium plugs but was curious if these things were even better, after all anything that improves fuel economy/better performance I'm up for it.

I learned here that Motorworks (BMW parts specialist) supply Brisk plugs, and they are still on Motorworks' website.

The concept of multi-spark from one plug seems to be a poor man's twin (or more) plug setup. You can find research online showing that when running lean, which is bad for flame propagation, multiple spark plugs really help, especially if each spark is timed independently.

Since we don't run lean compared with modern engines, the benefits (if true) are likely to be lower than on a modern engine. Whether their design makes the burn more efficient probably varies from engine to engine.

It looks as though another factor is indexing, i.e. a regular plug will vary in effeciency, especially when running lean, depending on the angle the out electrode is at in the combustion chamber. The Brisk plug may overcome that issue.  According to Wikipedia, though, the plugs with side electrodes can be less efficient. Some of the Brisk plugs have side electrodes, some have a dome (see pics on ebay). It is safe to assume NGK and Champion are aware of these ideas (Wikipedia has a picture of an NGK plug with two side electrodes).

Another thing I found out is that, especially when running lean, a high-energy long spark can also help flame propagation, but wears out the plugs faster. The Ebay ad for Brisk says '..not requiring much higher ignition energy supplied by the ignition system..', in other words they draw a little more power, so I'd be worried about my OEM coils.

I did find a match for our CB500 on the USA site under non-automotive. There are UK suppliers, e.g. http://www.gsparkplug.com/brands/brisk, no need to order from USA via Ebay. Looks like Brisk are a pretty big company. It would be good to have feedback on how they work on CB500.
