 On my race bike, I have the oil tank mounted low, and the head drains go straight to the oil tank. \\
 Eliminates the entire need to pump it out of the motor. \\
+You can also block the drain holes in the heads and add external drains so the oil can go into the cam chest through the cam cover. ((mac93 of the XLFORUM http://xlforum.net/forums/showthread.php?t=2002736&page=2)) \\
+Pre-98 engine cases drain in the cam chest to the crankcase. \\
+For those, you can also plug that drain and pipe the rocker box drains externally. \\
+In 1998, the MoCo got rid of that drain passage and put a scavenge inlet into the neck of the pump to pull the oil directly out of the cam box. \\
+You'll need a 98-Up style oil pump with the cam chest drain port built into it to make this work. \\
+See more on the different oil pumps [[techtalk:evo:oil03|HERE]] in the Evo section of the Sportsterpedia. \\
