just cleaned in the first pic

 

Pic 1 (clean)
Pic 2 (dirty)

Well the resolution makes it hard to see the plug in pic 1. IMO plugs are cheap enough that I'd just get a new one and keep this one as a backup. How long has it been in the bike, and have you fixed the rich condition that led to the buildup?

 

didnt even know if it was rich? i assume it is..yeah sorry for pics cell pic

 

If you're going to do a plug check it is best to do it with a fresh plug and just run it until it gets hot then check it. Also, something I learned, a plug can give off spark and still be bad. I had a bad plug on my Grizzly but when I took it out and held it against the engine and hit the starter it still sparked so I thought it was ok and there was something else wrong with the bike. Before I started messing with anything I put in a new plug and it fired right up and ran perfect. Just something to keep in mind if all of a sudden your quad won't start.

 

I just see that it was pretty much all black in the dirty pic, I figured it was carbon buildup. How long has the plug been in the bike? If its been a while it may not be any indication of the a/f mix.

 

hasnt been changed in at least a year
