After being deep into the bike I can absolutely see where the problems or potential problems are. The biggest being the lack of the 2 locating dowels in the transmission case. Without them.. there is at least an 1/4" of play in the inner primary housing before you tighten up the 5 sealing bolts. Even with them fairly snug you can still move the inner primary housing an 1/8" up and 1/8" down. This is absolutely the culprit when it comes to inner primary bearing failures. You CAN put it on straight but I would bet a lot of guys don't realize there is play in it and they just torque it down. That's a problem waiting to happen. Cut off the race with a dremel tool and install a Baker sealed bearing and put the inner primary on as straight as you can by eye and feel and you should be good to go.
The 8 compensator cup/rotor bolts is a just plain stupid design. Mine were all tight as could be but there are many many cases of them coming loose and tearing up your stator leaving you stuck on the road. Just get the little 8 bolts tack welded and that solves that problem or potential problem. I replaced the stock automatic ratcheting Harley Primary Chain Tensioner with a Hayden M6 BT07 for one reason. I have several friends with 07 Big Twins and a few of them have had Transmission failures at around 35K. They ride their bikes HARD. The problem with the stock tensioner is under high RPM shifting the chain moves around a lot and the ratcheting tensioner ratchets up and can't ratchet back down. This puts too much stress on transmission input shaft which screws up the bearings eventually. The Hayden solves that problem. The Screaming Eagle version solves it too because its not automatic. You need to set it correctly and it stays like that until you adjust it again.
