Hi Folks,

Yesterday I noticed the Water Coolant warning indicator come on (red) while riding around town. approximately 5 mins the warning indicator light turned off.

Today I removed the housing protecting the coolant header tank: the levels seem okay (full) and the colour of the coolant matches that of the refill bottle I have.

I started up the bike and left it running for about 5 mins with the header tank cap off. The heat radiating from the engine, coolant hoses and radiator was hot, but i was unable to see any movement (flow) in the header tank, as one would see with a Cars' Header tank.

Is there any possibility to produce the effect of water flowing, so as to see if there is any fault or obstruction and to see if coolant is circulating through the system properly?

Could there be an Air bubble or some pump not working?

Thanks in advance.

Kind regards,
