Long story short, while putting bike (03 fatboy) away for the winter I slipped and dumped the bike on the primary case side. After picking up bike found what looked like a couple ounces worth of transmission fluid on the floor. I know it's transmission fluid as I use Redline brand transmission fluid. Curious how it could of came out as I assumed this is a closed type system. I find nothing cracked or broken. Any suggestions would be greatly appreciated. Thanks

 

Leaked out the transmission vent on top of the tranny.

 

Thanks Joe. Sorry for slow getting back here, work seems to get in the way. I guess I should of guessed there would have to be a breather. I haven't seen it so I just have to search harder. Thanks again
