So I've gotten the junked 79 Express running now and it seems to be doing ok... until it runs for a while and the cylinder head begins to smoke. My intuition tells me that this is running hot... unless this is normal. It IS on the center stand though so there is no air flowing over the fins, but I cant imagine that this minor enthalpy would make that huge of a difference. Generally I have to let it run for three or four minutes at a midrange throttle before the smoke starts.
Any ideas or am I just being way to overprotective.
Thanks in advance.
