Dude i had the SSSAAAMMMEEE problem cause id idnt kno WTH i was doing but it was EZ when i looked over the TSRM
Put the HUB on the PP. Using the appropriate snap rings to hold it in place. Take the fork OFF of the transmission and keep it off untill the transmission is on the motor.
Put the clutch disk and pressure plate on the transmission. Bolt it up then bolt down the pressure plate. Once thats done slide the fork into position and then thats it.
^ I hope that process is correct, im just going off of memory but check out the TSRM
