There's a lot of crud at the bottom of my crankcase. I was hoping to blast it all out with cleaner so I could avoid cracking the cas of my 1970 750. My question - can I split the cases without removing the rotor? I just want to get in there and clean the crud. If I must remove the rotor, does it tighten counterclockwise? From what I'm reading, it sounds difficult to remove the bolt on the left side that holds the rotor on....
