its an 05 crf250 i took it to mexico ran it in the dunes, ill admit it was running pretty hot. when i get back i notice coolant all over my cases, coming from the overflow tube. may have overheated, not sure. but now everytime i run my bike coolant starts to leak slowly after like 10 minutes dosent matter what im doing with it. theres no smoking, no funny noises or power loss... what happened?
