After diving it for awhile to get it good and hot and not doing alot of idling, shut it off and let it cool. Pull the spark plugs and see what they look like. If slightly brown, I wouldn't touch it. If they are black, then you may want to look into rejetting, but if it runs good, I wouldn't mess with it.
