[QUOTE="MotoMike, post: 1463577, member: 92743"] Update: I managed to erase the fault codes. No fault codes recurred. I had the battery load-tested: Good I checked the coils with a tester: Good I pulled the spark plugs. Plug from #3 cyclinder looked carbon fouled, so I changed all the plugs. Bike started right up on first try!!!!!! I checked my maintenance log: The last time they were changed was June, 2020 (28,963 kms ago). OOPS! Moral of the story: Keep up with the maintenance schedule! Plugs are to be inspected every 6 months/4000 miles/6500 kms. Plugs to be replaced every 12 months/8,000 miles/13,000 kms. New problem: It looks like the engine coolant temperature sensor has failed. Yamaha Canada has one, but it's quite pricey. Same for Partzilla. [TABLE] [TR] [TD] [/TD] [TD][/TD] [/TR] [/TABLE] Does anyone have a bike that they are selling off for parts? I could use: 8CC-85790-01-00 THERMOSENSOR ASSY. That would be part #17 in the "Electrical" microfiche. [/QUOTE]
