at some point harley came to the idea the main crank seal was installed backwards inside the primary so they turned the seal around
as the idea goes - if you run gear oil in the primary it will be a bad idea to drive it till its convenient to replace the seal < and yes install it open side facing you dont cheap it out change the race as well

I had the same problem, for years! I would carry a turkey baster, and every 50 miles, have to move oil from the tank to the primary. Everyone said I was nuts, it didn't go that way! Well, it did, for 3 years it did. Don't put primary oil in the primary, it's too light for the engine. I just put 20-50 in the primary, and it would get sucked into the engine, it never hurt my clutch. A shop had rebuilt my bottom end, and ever since that, I had that problem. I took it back to him 3 times, he'd take it apart, replace the seal, and it would still do it. He finally just shrugged his shoulders! I finally found a guy that had seen the problem one other time, and he fixed it. Replace the seal AND the spacer, run a bead of loctite on the inside of the spacer, problem solved. The oil was getting in behind the spacer. Don't let anyone tell you "it doesn't go like that", because it does.
