Losing Coolant

[lake]

Lately my cr 125 has been leeking coolant pretty quickly. It's coming out of the overflow tube. I have a hunch it could be a bad cap and it's not keep pressure. Does anyone else have any suggestions? Or should i just go and buy a new cap?

i would prolly try the new cap. i think thats really all it could be?
does it do it more when the bike is hot? less?

If you have a friend with a similar bike try swapping radiator caps as a quick test.

It could be just a bad cap, but it could also be a leaking head gasket.
