You have to pull the clutch basket off to get at and un bolt the bearing retainer.
Pull the flywheel off to get at and unbolt the stator/plate.
Can leave the gear on the end of the crank shaft, unless your changing that side (right) crank seal (which you should change them all anyways seeing that your going to be in there).
Kicker shaft/gear can be left in but it slides in and outa the case in 1 second. Makes things easer with it out.
Idler gear can stay on also.
Use a rubber mallet to split it, don't use a metal hammer + hit where the clutch cover and flywheel cover bolts go so you don't crack the cases.
If you need a hand or get stuck just ask, i have a shit load of detailed picks ive taken of every nut and bolt for the engine being taken apart and then built inside and out, step by step.
Pressure test it when done, then rock out!
Very simple stuff.
What are you splitting for?
Have fun.
