I have an issue where the ZXR gets hot (3/4 to full on temp gauage) when caining around, and this causes the coolant to bubble out of the overflow on the header.
It has now stopped doing this, but in order for it not to bubble over, the header tank is empty when cold
![confuddled confuddled](./images/smilies/icon_e_confused.gif)
Any ideas as to cause / solution?
I have taken the rad cap off and filled it to the top (to ensure no airlocks), then ran it, and did it again.
Rad is staying full (I think, better check now, lol) but header tank is bone empty (Until she gets warm).
Cheers
