Hi all. Some helpful advice, please - 2006 FZ1-s.
Some months ago I drained my cooling system and refilled with a 50/50 mix (antifreeze/distilled water), however, ever since then my bike is very quick to overheat/boil, and then the expansion tank levels drop and requires a top up.
Whilst on the move it will run around 80 degrees but as soon as I hit crawling traffic/stop start, it reaches 100+ very quickly.
My feeling about the problem is a likely airlock which will not disperse. Or, maybe it is the mix? Anyone had this self same problem? The system is not leaking other than the overflow pipe when boils.
Any advice or suggestions welcome. Also, what is the best way to get rid of a potential airlock?
Thanks in advance.
