I have a 87 FLHTC. The manual says 44-48ozs. I always have put in a quart and a half. Never had any overflow issues. You said it was 100 degrees. Maybe somthing expanded from heat. Just a thought. Look at the inner primary seal from the bottom, maybe clean it and keep an eye on it. I would redo the primary gasket torque to spec. Look around inside the primary with a good light see if you see any cracks or anything else. I use black permatex on the gasket on mine.

Thanks for the petcock info, i will check this when i do the service this coming week.
The thing that alarmed me the most was that i was about 300mi into a 700mi trip that i was making in one day and the amount of oil that was on the ground. A few drops not that big of a deal. This has not happened since. Thanks again folks for the tips it is a great help to me as i am a newbie with the american iron.

I had an unusual/occasional "oil" leak problem which only happened once or twice last year. After investigation it turned out that the "oil" was coming from the Crankcase Breather. There is a pipe from the Breather which enters the Air Filter Housing (l/h side) and exits (r/h side or under) with excess " breathed" oil from another pipe down to the front of the Crankcase. Maybe your breather pipe exits somewhere else and that is where "leak" is coming from. Just a suggestion. Bungo

I have a 1988 tour glide with 25,000 mi on it. I bought it almost two years ago with 22,000 mi on it. This is my first harley and I really enjoy this bike. Since I have had it it will leave a small spot on the garage floor (not a big deal) about the size of a quarter maybe bigger. On a trip up to salt lake (about 700 mi one way) I stopped to get some gas right before I got into utah and ate some lunch and before i got on the bike I noticed a large pool of fluid under the bike. Unfortunaetly i really could not see where it had been leaking from. The engine oil was full and when i checked the primary it took about a quart. Since this happened I have probably put another 1500-2000mi on the bike and this has not happened again.
I am puzzled, any ideas on how this could have happend, what may be some things to check or look out for?? I have the service manual and enjoy working on my bikes. Thanks in advance guys!

My drain plug leaks too. I've tried teflon tape, pipe sealant , gasket silicone and still no luck. I even bought a new drain plug (wasted my money). I changed out all the gaskets and I'm pretty sure it's the drain plug. I use ATF in the primary, RP in the trans and Mobil1 in the engine so I know it's coming from the primary. This is really pissin me off. Any ideas?
I know this because I've stuck a rag up as far as I can on the outside of the inner primary, and it's always wet on the outside. I haven't gotten around to fixing these primary leak(s), because I haven't gotten sufficiently motivated to pull the inner primary and all that that involves yet... I will this winter when there's no riding to do!
