+====== Primary Oiling ======
+\\
+====== Transmission / Primary Vent ======
+-1976 models vent the primary thru the motor internally via the oil transfer valve. [[techtalk:ih:oil01#transfer_valve_76_and_earlier|Click here]] to read more on the transfer valve in the Sportsterpedia. \\
+-1985 models vent out the back of the motor from the top of the transmission near the rear motor mount just behind the solenoid (1/4” hose fitting). \\
+**Routing the vent hose**:
+  * Note: The transmission vent hose routing on Late 1981 XLH/XLS models was changed per Service Bulletin M-813 to reduce excessive oil leakage from the transmission.
+    * Early 1981 models can be changed to the new routing.
+    * The vent hose should be routed under the starter, over all the oil lines and the rear brake line, then down between the pivot bolt and swing arm. ((HD Service Bulletin #M-813 dated January, 30 1981)) \\
+Generally speaking, the rubber hose should run up under the seat and curl pointing down. If it has rotted or come loose from the fitting it can make a mess of that area.  ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?p=5779702&highlight=transmission+vent#post5779702)) \\
