Just a quick question as the "knuckleheads" around me seem to know it all except a solution to my dilemma at hand. I was hoping somone on this kick-ass website could take a minute to answer a quick question. I let my 92 evolution Fat boy sit for three months and now when I turn it over it pumps all the oil out the overflow hose onto the ground.I was told it bypassed the check valve and is normal.However the more oil I add just ends up back on the ground. Is the check valve fucked up? If so where is it? IF this question seems lame well maybe it is, yet the fact remains. Thanks for reading this got any ides?
