On my 06 Polaris fusion 600 the oil light when at a idle till almost 4000 rpms will flash. once it gets to the taking off point it stops. what could cause this? it not getting enough oil? and the heat exchanger under the tunnel does not get warm. I have tried to bleed it few times. do you think I have trapped air in it still? and today I was riding around lawn little bit and it died on me. I put jump pack on battery and it fired right up. does it need a charged battery to run?
