Since heat and deposits willcause any spark plug to slowly erode,they should be removed and checkedin accordance with the periodic mainte-nance and lubrication chart. In addition,the condition of the spark plugs can re-veal the condition of the engine.The porcelain insulator around the cen-ter electrode of each spark plug shouldbe a medium-to-light tan (the ideal colorwhen the vehicle is ridden normally),and all spark plugs installed in the en-gine should have the same color. If anyspark plug shows a distinctly differentcolor, the engine could be operating im-properly. Do not attempt to diagnosesuch problems yourself. Instead, havea Yamaha dealer check the vehicle.If a spark plug shows signs of electrodeerosion and excessive carbon or otherdeposits, it should be replaced.1. Panel A1 1. Panel A2.
