Remove the plug and inspect the insulator If the insulator is a light brown color it is accep table If it is blackened by carbon it should be replaced by a hot type NGK B7ES or NIPPON DENSO W22ES and if baked white by NGK B9ES or NIPPON DENSO W27ES Plugs with high heat range number are used for high speed running These plugs are designed to be sufficiently cooled to prevent overheating and are called cold type plugs If a plug with too high a heat value is used the plug will be overcooled with the result that insufficiently burnt carbon will be deposited on the insulator and electrode A large amount of deposited carbon will prevent good sparking Carbon deposits tend to get red hot themselves resulting in pre ignition or knocking When the temperature of the engine is relatively low for example when the motorcycle is always run in a town or subjected to breaking in without running at high speed plugs with low heat range are used These plugs are designed to prevent heat dissipation and are called hot type plugs If these plugs are used for high speed running they may be overheated resulting in overheating and pre ignition of the engine The plug gap is adjusted to 0 6 0 8 mm 0 024 0 031 in The gap is correctly adjusted using a thickness gauge special tool 09900 20803 When carbon is deposited on the spark plug remove the carbon with a spark plug cleaning machine or any tool with a pointed end If electrodes are extremely worn or burnt replace the plug Also replace the plug if it has a broken insulator damaged thread etc 09900 20803 Fig 11 7 11 4 Thickness gauge C hjhm Jie ihuad MZC t nd ta h the big th teach k oo ital on hill be dcpt md on IK SUCH rutitot of i k pl eg h K ord hillbeduo t d Fig 11 9 Normal carbon Fig 11 10 Overheating condition Fig 11 11 Wet fouling of Fig 11 12 Carbon stained plug
