I just recieved my Mag in the mail today. Just wondering where oil is needed and what to replace when. Also, my friend says that aftermarket internals are better than stock internals. NO THEY AREN'T. Can someone back me up here with some technical terms? Also, where is the air going when its in the back half? Does it come through the regulator seat in the front and then back through the one on the side? Let me know...and thanks for your help!
