E3 plug failed
I had to pull the bike out of the garage today to move stuff around. Started up and ran it back in and suddenly it started missing on the rear cylinder. I pulled the rear plug and it was wet. Swapped it with the front and sure enough it was the spark plug. E3's with less than 2000 Km on them. Thing ill go back to stock plugs. The E3s seem to start the bike better but then again, there never was a starting issue with stock.

I had no issues at all with them. And it did start better. I'm an engineer and I am perceptive to every little noise, rattle, misfire etc etc on a motorcycle almost to the point of being obsessed. I want my bike to run its best, look its best and be as dependable as I can possible make it. Yes I'm obsessed with my skoot to the point of wiping and waxing the frame periodically. Is it dumb? Is it a waste of time? Not when my life depends upon it. I don't hose my bikes down, I detail them after every ride. I look for leaks, cracks and any and everything that should not be there. Some have called these "glamour plugs, hokey and gimmics", but the detail I go to on my bike I can attest they start it better. The physics behind it backs it up, however are they worth the expense? I don't know, is one "oil" better than the other...........oh $hit, I went and mentioned "what oil is better'....sorry sorry sorry....lol

Here's a truth:
every manufacturer wants to advertise "more" power, "more" mpg without adding more cost.
if any doodad did that- the manufacturers would add it from the factory and every car and truck out there would tell you how they have more power and more mpg.
doodads and unicorn dust may mask something else which results in a perceived problem, like a mis-map or a dirty sensor, or a bad connection.
multiple electrode spark plugs give more possible variation in burn time ( do we have 1 spark or 3?) ...is the burn then 3ms or 1 ms?
and on recent model bikes may interfere with the ion sense, which the ecm relies on to calculate the results of fuel/air and spark timing in the combustion chamber (and this may happen with any other than stock spec plugs and wires...even screaming eagle)
some aircraft engines have been designed to use multiple electrode plugs.

I would have to dig back through too many dead brain cells/memory to give the answer I should give but the plug has nothing to do with it being wet. Never been a fan of gimmick plugs, have tried them in bikes and cages but you need to look at the true cause of why the rear cylinder has a wet plug.

The rear cylinder had a wet plug because the plug stopped firing yet the injectors continued to throw in fuel. I put the bad plug in the front cylinder to see and it wouldn't fire the front cylinder. the plug would not fire. Swapped it out with stock and all is good. Never had an issue with this bike and I maintain it to the nines.

A spark jumps the shortest route. When one electrode wears away and another becomes the shortest rout, the sparks jumps to that electrode. It isn't like having 3 spark plugs because all of those electrodes get dirty at the same time.
Aircraft don't enjoy the same "luxury" of pulling off to the side of the road when the engine quits. If one electrode burns away or breaks off, the other one will continue to fire. Redundancy.
