Just got back from a 10 mile ride. Still fouled the left plug. The plug was black and dry by the time I pulled it out, but I waited 10 minutes before pulling it to thaw out my hands, so it was probably wet when I stopped. It had a pretty good stumble at 1/8 to 1/4 throttle, but I don't know if it was the plug not firing or something else. I think I've done all I can do and may turn it over to a dealer to sort out if the guy who owns the bike says its OK.
