 If you don't want the leak, you can try and tighten the adjusting screw. \\
 But chances are the screw or fitting itself has previously been tightened too much leading to an eternal leak. \\
-Most will either plug the oiler fitting with a bolt / screw or remove the oiler fitting and install an 1/8"x27 NPT plug there and oil the chain by other means. \\
-You can also run alternately run a hose from the crankcase breather pipe back to oil the chain (mostly oil mist at best). \\
-However, it is far better to use a good quality chain wax. It won't fling off all over the bike or rear tire. ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?t=1559852)) \\

-  * 1967-E1972 XLH and 1970-E1972 XLCH used a (63595-67) hex body flared connection regulating fitting with a mounting tab to the top of the motor behind the rear sprocket.

+**Adjusting Screw**:
+  * **1953-1956 K Models / 1957-E1960 XLH**: \\ Original hex head CAD adjuster screw# (63610-53). \\ Original screw was replaced by hex head screw (63610-53A) in L1960 and replaced again by (63610-70) in 1971. \\ Original "plain" #10-32 x 3/16" x 3/8" washer (6156) turned into a brass washer at some point in time. \\ But the part number stayed the same for the washer. \\ It had a #10-32 x 3/16" x 3/8" hex nut (7630) to tighten up the screw.
+  * **1958-1969 XLCH**: \\ Original adjuster screw was included with the oiler fitting (at the oil tank). \\ A Chain Oiler Screw Kit (26383-32) was available for parts order in 1963 to replace the existing adjuster screw. \\ The screw kit contains a parkerized fillister head screw, (1) thick washer and (4) extra thin washers. \\ The HD "Genuine" accessories replacement fitting has a 3/8" hex head screw. \\ The screw was replaced by (63610-70) in the 1971 parts catalog.
+  * **L1960-1970 XLH / 1970 XLCH**: \\ Hex head CAD adjuster screw# (63610-53A) with no washer and a plain #10-32 x 3/16" x 3/8" hex nut (7630) to tighten up the screw. \\ Original nut was replaced by a #10-32 x 3/16" x 3/8" hex nylock nut (7626W) in 1965. \\ Original screw was replaced by (63610-70) in 1970.

Screw looks identical to the -53A screw but it has added lockpatch on the threads. \\ Some HD Genuine replacement screws come with a #10-32 nylock nut to tighten up the screw. \\ Others only come with the screw itself. \\ This may be the reason for the verbiage in the FSM stating to tighten the nut (if used).
 **Adjustment**: ((1957-1969 Sportster FSM pg 2B-3)) ((1970-1978 Sportsters FSM pg 2-2)) \\
 Inspect the chain at regular service intervals (1000 miles) to see if it is getting enough oil or too much oil. \\
 To adjust the amount of oil given, loosen the lock nut (if used) on the fitting and turn the screw outward for more oil or inward for less oil. \\
-Only turn the screw a little at a time and tighten the locknut (if used) on the screw when done. \\

 Reinstall the screw until it bottoms out and back it out the number of turns counted earlier and lock it in place with the locknut (if used). \\

+**Blocking Off the Chain Oiler**: \\
+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. \\
+Or you can plug the oil path at the source (right engine case or oil tank respectively). \\
+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. \\
+Then you'll need to oil the chain by other means (chain wax, other). \\
+You can also run an alternate hose from the crankcase breather pipe back to oil the chain (mostly oil mist at best from the breather). \\
