Hi,can somebody help me.I'v got gsxr 750 K5 and my problém is engine coolant temperature on speedometer show me high temp even before first start engine just ignition is on is temp about 50C and increasing to 80C. I checked thermostat,ECT sensor and fan on radiator. All ok.*

you do know these bikes have an ambient air temp sensor right?

on a really hot day, if my bike has been sitting in the sun, my bike will read 89 F before I even start it.

dunno how hot 50C or 80C is, but I'm pretty sure that's just the temp outside.

edit: LMAO nevermind....50C is like 130F definitely not that hot outside. Is that after you have ridden the bike a bit and stop and attempt to ride it again or is it reading 50C or 80C after it sits overnight?
