Oil Pressure Light On at Idle, Kawsaki EX500?

Question

The oil is topped off, recently changed out oil sensor unit for brand new on. But the light still goes on once warmed up at idle up until about 2000 rpms. I have "burped" the system aswell to get out any trapped air but still no avail. Once I throttle past 2000 rpmsthe light fades away. Bike only has 4000 miles on it and runs great. I can't figure it out. I am using 20-40 oil, in NY.

Answer 1

Sounds like your oil pump is getting weak. I would look for a new pump and replace it.
