+A lot of folks don't like the constant leak when the motor is running from the chain oiler. \\
+(or the draining of the tube on the floor when shut down) \\
+As long as the threads on the fittings will seal, you can simply turn the adjustment screw (clockwise) to a light seat to stop the oil flow. \\

+You can either plug the fitting at the source with a bolt / screw or remove the fitting and install a 1/8"x27 NPT plug in the case. \\

+**Installed Pics**: \\
+Below is a L1962-1965 XLCH "horseshoe" oil tank with an explanation of how the chain oiler gets it's oil. \\
+The blue line is the oil level. The red line is a tube inside the tank. The bottom of that tube feeds the lower (chain oiler) fitting. \\
+The top of the tube is open and above the oil level. So, nothing drains out of the bottom fitting if you open it. \\
+Note the open top of red tube is directly below the return fitting. \\
+When the bike is running, return oil spills into the red tube to supply the chain oiler fitting installed in the lower port. \\
+This feeds chain only when the engine is running and doesn't leak when the bike is shut off. \\
