I have a 1966 CB450 I just pulled out of a barn. It has a Harley tank and needs a lot of love. It hasn't been started up since 1983. I just finished rebuilding the carburetors and am ready to see if she will fire up. I would really like to know if I am getting oil pressure. I don't see any type of sensor on the engine, am I just not finding it? What is the easiest way to know if I am getting oil pressure?
