Japanese fours are built in one unit. They have a horizontal seam. Access to the bottom end comprising crankshaft and trasmission is what you need. As mentioned above, to do this you would need a Bandit Factory Manual.

I don't have a Bandit, but an old Kawasaki 750-4. My factory manual tells me to disassemble clutch, get the engine out of the frame, turn it upside down, and proceed unbolting, spliting the cases, and removing the bottom end to access the tranny gears and shafts. On the pictures, crankshaft, cylinder block, and cylinder head are still attached on the upside down engine even though the whole bottom is out. Most of the tranny parts remain on the top case, but manual lists a few parts coming with the bottom. Likely Bandit is similar as it has generic japanes four architecture, but better get a manual.

This is a big job, make sure noises are not coming from sources that don't need taking the engine apart, like clutch, sprockets, drive chain, or shifting mechanism. Once I started hearing this rattle on acceleration, and was fearing the worse swearing it was the cam chain; it turned out the drive chain was a little stretched and was rubbing on the sidestand.
