Coolant comming out of header tank vent

I have been having problems with the coolant blowing out the vent in the recovery tank vent when climbing, at cruise it's not an issue the CHT all stay at 100deg C, on climb they go up to around 125 in around 2 min level out and they drop back to 100. i have changed to coolant using 50/50% this droped the temps by 10deg however the venting also happened at a lower temp. when it vents out the recovery bottle, the level in the bottle remains the same? I live in the tropics high hum, temps between 20-33 deg C. could this be air locks in the system blowing bubles back to the tank?
Aircraft is Skyfox same as kitfox however the radiator is in behind the engine under the top cowl, all the Kitfox that i have seen have it under the bottom cowl.
If i keep the CHT below 125 its not an issue but you can't maintane climb. Climb is normaly 500FPM at 5000rpm.
any ideas?
