Running lean?

[xd45c]

Alright so I found some train tracks today and got to ride the Blaster hard for a couple hours today, plenty of WOT in 6th gear. When I got home I pulled the plug and this is what I got:

Is this the "gray" , running lean color, or something else?

I'd be more concerned if it was a white ash color, But looks like you might be just a tad rich over all. You would need to do a plug chop to know for sure. You would have to run it wot in 3rd or 4th gear, and without droping the throttle hit the kill and pull the clutch in. Then check the plug.

Yeah I'm going to do a chop the next time I go riding there, previously I didn't have anywhere to do one but next time I'll give it a go.

Pictures are hard to see stuff sometimes but it looks ok to me. Being a little fat is ok, It's easy on parts. Everyone wants to set the fuel on the verg of being too lean. Only if your racing should you be leaning down a good running bike. Imo

Yup I'd agree, tad rich is better than too lean. I:I

Forgot that you get a better reading on a fresh plug.

Will do a chop on new plug next time out, thanks for the replies guys.

you read the base of the insulator, not the tip. also if you were running slow before turning the bike off, you looking at a partial throttle reading, not a main jet reading.
