tons of exterior mods, powertrain is stock w/stage one

Over the winter the bike was sitting upright on my table lift. Been riding it all summer and just this past week (was sitting off the lift on its side stand, while on vacation w/family) I came home to notice a small amount of oil on the floor under the bike. I can't see where it is coming from and all around the primary/pulley its dry. No where I touch its wet. At first I thought maybe trans fluid but its not (i use spectro which is green in color) this is oil ....Nothing is over filled and its only been since sitting for a week on the side stand....

Just wondering on a 2012 what it might be...I heard the mainshaft bearing can walk and cause a leak but I thought that was earlier year bikes....

Anyone have any idea's? of where I should be looking? going to be a winter project if I have to tear into the primary but thought id ask first...

 

First get a mirror and a trouble light and start looking. I just went through this on my Ultra. It would leave a spot on the floor about the size of a 50 cent piece. After some digging I found it to be my transmission seal. I tore it down and replaced all seals since I was going that far.

Other things I looked at were inner primary O rings, (replaced) stator plug, and a loose primary drain plug. All to find the "leak spot". Something else I was torn about was the amount of primary oil to use. (I only use a qt) No matter what the manual calls for my Indy says never to fill to the bottom of the derby cover like some manuals call for. Only fill about a 1/2 inch up the clutch and no more. Transmission vent was also looked at to make sure it wasn't plugged. Hope this helps some.

 

What seal has oil 'pressing' against it when on the kickstand, and doesn't when straight up?

I would take a good look at the primary / clutch cover seal.
