Cooling problem on my tecate

[rippn250R]

When I run my 85 tecate antifreeze shoots out of the overflow hose, and next thing i Know my radiator is empty. I thought it was the water pump but thats works fine. Could my radiator be clogged? or is it a bigger problem?

could be a bad head gasket.

yes, that is probrably what it is...the engine is pressurizing your cooling system and forcing the antifreeze out
