Spark plug gap?

I went out and pulled the plug. Is is black and wet with fuel. New plug has less than 20 miles on it.

They come pre-gapped, but I always double check. Thanks!

Sounds like a carb problem. Sticking float possibly. Sometimes they will flood when the bike is off and you'll have to rev it a bit to burn the excess fuel. A black wet plug is an indication of that.

Maybe the needle valve not seating properly?
