2003 FXD with 60,000. The engine warning light is blinking. If I shut the bike off and restart it no longer is blinking. I read my user and repair manuals, but found no clues. Bike runs fine. This started Sunday. Saturday I rode 300 miles. Sunday, cleaned the bike as always, changed engine oil and filter, changed primary oil, adjusted the clutch and cleaned the air filter. I have always been careful washing the bike by hand with warm soapy water, a garden hose for rinse and the leaf blower for drying. What is the warning light trying to tell me?
