spark plug chart link
its been posted a hundred times but maybe you havent seen it yet
Although I have not seen this page before, I have seen many others, from NGK as well as in Tech School. The plugs in the first pic are good, sans the signs of detonation! Yes, that is detonation, microscopic particles of piston material embedded onto the facing of the plugs!
First thing that should have been asked: Was the bike ran up on a WOT Blast, then immediately shut down, then the plugs pulled for a true reading? If not, and the plugs were simply pulled after normal riding, then it is what is called a "wash." Wash is where you allow the plugs to experience different loads, AFR and operating conditions, the fuel and combustion will literally remove valuable trace from the plug as it cools down, and is subjected to light/no load conditions, such as deceleration.
If you want to read your plugs, and you see something like posted above, I would recommend you use a new set of plugs. Start the bike and let idle from cold to normal temp. Pull plugs, this will let you see what is going on at idle. Clean, or use new plugs, install and go for a normal routine ride. Pull plugs, but dont let the bike idle b/w your ride and the shutdown, or else the idle if too rich/lean will "wash" your readings. Then repeat but go do a WOT Blast and immediately shut it down, no coasting, decel, idle etc...Now you will have a true look as to what is going on with the tuning, at idle, low-load and rpm, and full load and rpm (I believe the PCIII also adjusts fuel in a similar fashion, but havent used one yet). You may end up seeing detonation at low-load/rpm, but not idle and not WOT. That would suggest reducing the ignition advance at mid-rpm/load.
The plugs posted, have signs of rich condition, the sooty area on them, but it is not "fresh" suggesting the bike was allowed to idle or decel. The rich condition may be at idle only, and decel will wash much of the trace from them. And this goes on and on.
I'm not posting this trying to start an arguement. I've been around plugs my whole life, and made quite a decent supplement to my living from tuning cars, which as far as plugs are concerned there is no difference what its used in, motorcycle, car etc...same goes for tuning AFR and Ignition Advance. I'd dont mind a discussion on this and I will remain open-minded to learning, but I just dont see where these plugs are "rich", look like sh*t, or necessarily need a new map, especially when no one asked what the conditions were, WOT, idle, low-load etc...
