So… on my 2001 ST4 the oil pressure light starts to flicker at the end of a few hour ride. Prior to this during a long summer ride in hot weather the oil light flickered and stayed on. After that long ride, I changed the oil and no longer experienced the flashing oil light. Now it appears to be back. My question for anyone out there is… What is causing this and what might the solution be? Thanks, Sent from my iPhone
