Splitting the Crankcase

So winter passed and I decided to do some maintenance on my 01 F4i. I got laid off at the end of February so I have ample free time and started with a compression test. 3 out of 4 cylinders tested in the 150 psi range and the last one 120 psi. So I popped some oil down the hole and it zoomed up to 160. From the reading I did it sounded like the piston needs a new ring or the cylinder needs to be bored.

Fast forward, I dropped the engine; removed the cylinder head; removed the clutch cover; removed the alternator cover; removed the oil pan and the throttle bodies. Now to split the crankcase so I can remove the pistons to replace the rings the service manual states I need to remove the clutch & alternator/flywheel both of which require a special tool which I don't have. But from what I can see the upper half should just split from the lower without disturbing either. Has anyone had experience in doing this? am I able to split the crankcase without removing both the clutch & alternator? Any help would be greatly appreciated.

Other details:
54,000 KM's/33,500 Miles on the bike

Well since no one else replied I answered my own question by powering forward into the unknown. You have to remove the oil cooler, clutch basket and main wheel bearing chain. But the alternator and flywheel can be left alone. The clutch basket is a 30mm socket.
