The condition of the spark plug can indicate the condition of the engine. Check the coloration on the white porcelain insulator around the center electrode. The ideal coloration at this point is a medium to a light tan color for a snowmobile that is being ridden normally. If a spark plug shows a distinctly different color, there could be something wrong with the engine. For example, a very white center electrode porcelain color could indicate an intake track air leak or carburetion problem for that cylinder. Instead, take the snowmobile to a Yamaha dealer for inspection and possible repairs. 1. Slot 2. Close the shroud. 48 Periodic maintenance You should periodically remove and inspect the spark plug because heat and deposits will cause a spark plug to slowly break down and erode. [. . . ] If the dealer is not able to do so, he is expected to contact Yamaha Motor Corporation, U. S. A. , for clarification or assistance. When contacting Yamaha Motor Corporation, U. S. A. be sure to include the model, serial number, names, dates, and receipts.
