The condition of the spark plug can indi-cate the condition of the engine. Check the coloration onthe white porcelain insulator around the center electrode.The ideal coloration at this point is a medium to a lighttan color for a snowmobile that is being ridden normally.If a spark plug shows a distinctly different color, therecould be something wrong with the engine. For example,a very white center electrode porcelain color could indi-cate an intake track air leak or carburetion problem forthat cylinder. Do not attempt to diagnose such problemsyourself. Instead, take the snowmobile to a Yamahadealer for inspection and possible repairs. You shouldperiodically remove and inspect the spark plug becauseheat and deposits will cause a spark plug to slowly breakdown and erode. Consult a Yamaha dealer before chang-ing to a different type of spark plug.AB
