Are the sohc heads known to crack.I have a 76 F model and looks like a crack in the square well under the cam tower.Can it be verified somehow before proceding. Also I seen on this site that the F model motor # should start as cb750ef.Mine is cb750e-2529974.According to Carpy's site that would be a K model motor.My bike is original surviver.Someone enlighten me thanks.
