Way back in 91 I did a cr500 and it was pretty straightforward like the manual states. I shot everything with liquid wrench a day or so before popping the flywheel/ mag rotor. The Cr is noted for gathering moisture down there and getting rusty behind the flywheel. The seal was just a pop and lube replacement if I remember correctly. Clean the crankshaft with fine emery. The timing is factory set. It can be modified with a timing light and you file the mounting hole to move the pickup but I doubt you would want to do that.
