What do you think of these plugs, Wierd color?

Thanks

 

I've gotta admit that them plugs look weird. The fuel that we are forced to use today make plug reading hard to do, especially on 4 stroke motors.

 

I have been playing with the idea of using octane boosters to stop ping.
In the past when I used octane booster in one of my street race cars, the plugs came out looking just like that.
I am interested to see if my plugs turn that color after a few tanks of octane booster in my bike.
The cardboard color on the porcelain is a safe color and not to hot but slightly on the cool (rich) side for performance. For best fuel economy, they should look much lighter in color (towards an off white).
The base of the plug at the threads should be a dry black.
Who knows what they are putting in our gas these days.

If this were one of my 2 stroke asphalt drag race sleds and the porcelain looked like that, I would lean it down for max HP.

Not a lot of info, only photos.
there are many variables.

Just my 2.

 

Actually, those plugs would not give me cause for concern; what I see is heat range too cold and A/F too rich. Get a set of NGK plugs that is a couple of heat ranges hotter than what you are running and check them again. Might be time for a fine tune.

 

Those plugs would be considered good on a 2-stoke!

If anything,the fuel may be a little rich but not too bad.

 

Thanks Guys, here is the skinny.

The plugs are stock HD plugs in my 2012 Dyna SG with about 5000 miles

I recently put a new Fuel Moto Tuner on it with their map two days ago.

I also used an octane booster.

The reason I pulled my plugs was because the bike actually sounded quieter than it should. I cleaned the plugs and fired it up and it sounded like it should.

So from your observations I think the tuner may be a little to rich and this with the combination of the Octane Booster caused my issue.

I am going to get new plugs and just stick with the BP 93 Octane fuel and see what happens.

What do you guys think?

 

If your motor is stock (is it?) there's no reason to use an octane booster. I would put in a new set of plugs and run a couple tanks of gas without the booster and see if there is a change. What intake and exhaust are you running? Need more info.

 

Exhaust is Screamin Eagle street performance slip ons and a Screamin Eagle stage 1 breather.

I was trying to eliminate decel pop. The Fuel Moto Tuner took care of that.

Thanks

 

The plugs shown indicate heat range too cold and an A/F mix on the rich side but not cause for concern. Nevil is right, you shouldn't need octane boost and it wouldn't elminate decel popping anyway. Maps are lacking, doesn't matter if they are H-D, Fuel Moto, etc. Even a map from a configuration identical to yours will not deliver an optimum tune.

Replace the plugs, I would go hotter at least one range; no octane boost and do a plug cut under load and at cruise. Get a couple of sets of new plugs and plug wrench and go for a ride. Wind her up in 3d or 4th gear to say 5000, shut off the ignition and pull to the side of the road; remove plugs. Replace plugs and get back on the road, settle in to a light load/cruise situation between 3000-3500 with steady throttle; shut off the ignition an and pull to the side of the road; remove plugs. Those two sets of plugs should help you diagnose the heat range, timing and A/F under load and at cruise.

If the heat range is right, go get the engine dyno tuned.
