i have a 1968 FLH and I did some work in the primary took it all apart and now it all back togather and never ran it. so inside the primary its all claen. Still never ran it and about a month later it sat. Now I went to change oil and I check out the plug on the interprimary to put a new o-ring on the plug and about a pint to a quart of oil came out of there. is that normal? I know oil gets in there and it gets sucked back out but it never ran. So all that oil got in there. i do know when I had it apart oil was seeping out from engine but not much. bike was level at time now on kick stand.

 

Put a big pan under the crank vent hose and kick her over a few times and see how much oil comes out the breather hose, you get a lot it means check ***** blead by and filled the crankcase and it's getting past the output shaft seal into the primary, the oil level in the tank will be pretty low if this happening. Only thing it can be unless oil lines are crossed somewhere.
