When I took out the plugs on LRB to fog the cylinders for winter storage, the right side spark plug electrode on the bike was quite white but dry and the left side was pretty well light brown, dry and near perfect. Does that mean LRB is running leaner on the right side? Do I reset the air/mixture adjustment as per our owners manuals? Which way should I turn the adjustment screw to make it just a tad richer? Bike runs great. Even worry about it at all???
