[QUOTE="Gary, post: 540949, member: 3075"] This makes me think one of the sensors that supplies the ECU isn't doing its job. I'm thinking coolant temp sensor (tells the ECU that the bike is cold and to adjust fuel delivery accordingly) or O2 sensor, which can be a complete wildcard for symptoms. I don't know where the temp sensor on the FJR is elevation-wise, but on my car it's almost at the top of the cooling system, so if the water level drops by a little bit, she runs like hammered crap. So I'd check the coolant level. The REAL level, not the overflow tank. [/QUOTE]
