What does this spark plug tell you?

Sorry I have to do this, but I just don't know how to "read" the way a spark plug looks.
So waht do you think? Do I need to adjust anything?

Thanks,

Tudor

Thanks for the tip. My needle clip is set second from the top. I could raise it to the first position, but i'm still during my break-in period. Should I do it now, or should I wait a while?
 
i will wait since you are on your breaking period what oil are u using like mine i am running 50:1 for my breaking and now i am running 100:1 i am using amsoil oil i was having the same problem but once i switch everything is fine now hopefully this helps
 
I'm running 20:1 non-synthetic regular cheap oil. I will switch to synthetic oil and a much leaner oil-fuel ratio after a few gas-tanks.
I've heard this is best for a new engine.

Hi,
I am the tech manager at Autolite spark plugs. Your plug actually looks very good for now. I would completely break it in. Then do a WOT run, chop the throttle closed and shut it off. Then you can really "read" the plug.

You haven't provided enough information about the running conditions of the engine and the type of fuel used and the oil/fuel ratio.

Was that plug pulled from the engine after light throttle use, or after idling for some time, or coasting downhill or wide open throttle?

Mixture analysis cannot be determined unless all these factors are known.

20:1 oil-fuel because i'm breaking it in. The plug was pulled after a normal (flat) 6 mile run and after the engine cooled off.

Thanks,

what percentage of throttle were you using for your 6 mile run?
What fuel were you using?
What was the air temperature at the time?
What was the level of humidity at the time?
What was your altitude at the time of the run?
 
Oh, come on! I may not know that much about these engines, but I know it's not rocket science. ALL this might be relevant for competition motorcycles, but i just wanted to know if the way my plug looks means i'm too rich either on oil or fuel.

Thanks anyway,

T.

Really guys, he was probly lookin' for a yes or no. Look great right now. Run another tank or two that way and you should be good to go. But even after, DON'T SKIMP ON THE OIL. Lifeblood man, LIFEBLOOD=)
