If they are still fairly new (less than, say, 2K miles) then they will be white if the engine is running good. As long as there is no blistering of the insulator there should be no problem. It can take a few miles for plugs to take on "color" if the engine is in good tune. Look at the base of the insulator where it meets with the shell of the plug. If you see a very thin black line there...you are good to go. Love the Baby GS, Australia (never met a Kangaroo I didn't like), and this forum.

Motor is running lean. Have you added an aftermarket air filter or exhaust without rejetting?
