• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Brisk sparkplugs

Im always afraid of this type of plug, heat range maybe off and burn piston.spyder has a pretty high compression ratio to fool with spark plugs
 
Verious forms of surface gap plugs have been around for some time. We had to run surface gap plugs in the early 70's 2 stroke Kawasaki triple motors because everything else would foul very quickly. The surface gap plugs would also foul but not as readily.

I sell the NGK Iridium spark plugs so you have to take that into consideration with my opinion. But I can say with confidence that the Iridium plugs are a proven performer. If I found that a surface gap plug was a better deal, I would go that direction myself.

My experience with this surface gap type of plug is that they are designed as a remedy for conditions in the cylinder (usually fouling) that are not optimal (like with my Kawasaki triple). There is a reason that the single electrode version of the spark plug is still around after so many years. The fact that most racing engines use a single electrode plug is also a great testamony.

As mentioned above, there is more to a spark plug than spark. Proper heat range is also very important. Surface gap plugs usually tend to run hotter (again, as a solution to fouling). This may not be a good idea in an otherwise properly functioning engine.

I'm not saying these won't work. Just that I'm going to let someone else try them out. I will be interested if someone gets these plugs to see what they think.
 
I would only use this plug in the ME5 Spyder. :roflblack: What the heck is a ME5 Spyder ???:dontknow:


Brisk plugs comes slightly different 360° gap shapes varying according to the current vehicle cross reference.

One other point for your consideration. The Spyder GS/RS uses an ionization current sensing knock control system. This measuers the "feedback" from the plugs to determine if the engine is knocking, and adjusts the timing and fuel mixture accordingly. Changing to a different type of spark plug can adversely affect this process, and could ruin an engine under the right circumstances.
 
:agree: Besides whats wrong with the stock plugs:dontknow:

The answer is Nothing! But that could also be said of the stock muffler, air filter, tires, handlebars, windshield, etc. The truth is, there is almost always something that will work better than the stock OEM item. And this is where the Snake Oil vendors try to cash in. Not everything that glitters is Gold!

You have to navigate the film-flam and get what really works. That is the beauty of a forum like this. Sooner or later someone will try it, no matter what it is. You can usually come here and find out what works before blowing a lot of money and ending up with 3 or 4 discarded trials sitting in the corner of your garage.

The stock plugs are fine and I am encouraged that now the Spyder comes with Iridium plugs. I think this is wise as the cost vs benefit is greatly in favor of this change. It also is encouraging to see that BRP is continually assessing the Spyder and all of its components looking for reasonable, cost effective ways to make improvements. This is not always the case with every manufacturer.
