I recently drained, flushed and re-filled my bikes cooling system (GSX-R750 K2). I followed the procedure in the Haynes manual, making sure I bled out any air (or so I thought?)
All was well for a few weeks and about 350 miles or so. I got back from a ride the other eve and noticed that the reservoir tank was almost completely full (way over the 'Full mark'. Normally when bike cools this returns to level between min and max.I went out again and noticed coolant ejected out of overflow and reservoir still practically full. What is going on? is it air trapped in system? I have now just drained Reservoir and topped up Rad which naturally was a bit low, and bled system again, any more ideas if this does not work?
