One right after a frickin nother!!!

Got done with a ride and pulled in he garage. Next thing I know there's a pretty decent size puddle under the bike. It's trans fluid from behind rear of primary. So I start taking stuff off, and when I get to the main drive pulley, the nut turns by hand, even with the torque plate attached.

What else should I be looking at replacing while I have it all apart? I did all the inner primary seals already.

 

Sprocket seal, quadrant seal and gear shift seal.
