I googled and googled. New and old. The old one looks funny. Trying to figure out what caused the disfigurement on the sparky thingy. It came out of my 530 tonight.
Someone will know, probably Hank, but I think the answer is in this article. Pre-Ignition I think.

I have always passed this off as electrolysis in action. The longer a center electrode is to the charge the metal will break down over time. Some seem to resist this better than others. I may not even know what I'm taking about here though.
Are they the same heat range? The used one looks like a lot hotter plug to me.
Are they the identical plug? Iridium plugs have a very small electrode versus a standard plug
Same NGK plug
wow I've never seen one erode that bad before.

Ryan wins the prize! Clean glasses, better internet at the office and a stop at the auto parts store.
It is an Iridium spark plug. All is well.
Thanks!
looks a little fouled as well. too rich or you have an oil issue.
Are you running diesel fuel in the 530? The plug will burn cleaner if you use gasoline.
I agree, must be diesel fuel.
I am pretty sure thats caused from excessive throttle use to much wide open.

I haven't had that problem since I graduated from 80cc bikes. ;)
