My bike had a coolant leak a few days ago and i think i rode it about 15 miles without noticing the coolant had all leaked out and now after fixing the leak and filling it up with coolant and changing the oil it now wont start and the oil glass showed it was full and milky looking. I drained the oil and i notice theres a bit of coolant coming out to, my guess is blown head gaskets but im not sure, do you all think thats it or something else?
