I had this same problem with my 1000-5. The machine was just in for the clutch cover upgrade after this was done the oil light would randomly come on. If you shut the machine off and turn it back off the light goes out. after a short time randomly it would come back on. Took it back to Honda dealer and the mechanic knew right away that it was a needle that he had to order from Honda for the clutch sensor oil sensor. It seems after the clutch cover upgrade with the extra oil flow the machine will idle down just slightly enough to trip the sensor. Apparently Honda knows about this issue and it's a quick fix that they purposely made a pin to keep the pressure up. Hope this helps
