Whats up guys I have a 2002 YZ 125. I just did a new top end on it about 7-9 hours ago, with that said. Last night I was doing my regular maintenance oil change, spark plug, all that good stuff. every time i do the maintenance i like to do a compression test (the plug is already out so why not). The compression was a little low about 130psi. So i was looking into why it was so low and noticed when it was running coolant was dripping out of the over flow tube from the radiator. I took the radiator cap off and saw bubbles coming out of the top of the coolant. This means the head gasket is bad right? The oil I drained out was normal color it wasn't milky or anything like that, the exhast never smelt like coolant, and the plug looked normal. So i guess i want the some advice as to if it is the head gasket or not. Thanks in advance for the help. And does any one know what to torque the head bolts at.
