Default Leaking Derby Cover Gasket after dropping

Yesterday I pushed my bike into my garage. There happened to be a little bit of loose gravel and dirt on the cement floor of the garage. As I was putting my kick stand down my mosey neighbor drove by, behind my garage. I got startled and lost my footing and the kick stand wasn't fully forward yet and as a result I dropped it sort of gently before leaping out of the way. I have a lot of junk in my garage and wasn't sure where the junk was in relation to the bike and was scared I would get pinned down, hence leaping instinctively.

Pissed me off, scared me, and gave me the nervous shakes.

When I first tried to pick it up I couldn't because I lost most of the strength in my arms due the health problems I deal with last year. I then remembered the skinny girl technique and lifted it up quite easily.

I immediately noticed a small amount of dark oil on the floor which looks like it is coming from the primary. I looked for damage on the primary and the entire rest of the bike and not even a scratch.

I kind of wiped the primary off and will have a closer look today. I am wondering if it is the derby cover?

Anything else I should be looking for that is common to get damaged or cause leaks from a minor garage tip over?

Glad I have the crash bars because that seemed like the only hard part to touch down.

I would take it out and ride it. See if it leaks after the ride.

Is it possible it came from the transmission vent being it was on its side?

Derby cover is dry.

I got underneath it just now and it is the primary gasket, in the rear section.

It did not leak overnight.

It only leaked while laying on its side. I don't see any scrape or evidence of damage.

I don't understand that.

That might make sense because the leak stopped as soon as it was righted. The funny thing is though it is only wet at the bottom of the primary, underneath the derby cover.

The vent for your tranny is on the left side and the oil could have come from there when you tipped the bike over.

Thanks for the quick replies that make sense and saves me some dollars and cents.

Since what came out was dark looking, I might just go ahead and change the oil in all three holes.

I hadn't ridden it in two or three months and yesterday I took it out for a glorious ride and went through a couple of tanks of gas.

I hope when I die (again) this bike will be waiting for me in heaven. I love this thing.

Got some very approving looks from late model Road King riders, especially after I started it up to leave the restaurant I stopped at.

Just check your transmission level with the stick. Really doubt it came from bike. There would be some evident of it on the bike. Could have been fuel from the top vent in the tank back thru the vent hose. I don't think there is any check valve nor is there one in transmission vent. RIP and I (no bike) but had a similar meal at an expensive place the other night. RIP got two asparagus sticks. We are still laughing about that. I hate expensive places that charge $10 for a bottle of water and give you two asparagus sticks.

It has happened.
On a '99 Street Glide a friend owned.
He dropped it at the end of his driveway and it tipped over far enough to leak out the vent line.
