Well.....unfortunatly.....you're going to need to split the cases I think. The only ball bearings in the engine are in the transmission and the starter sprag clutch assembly. I would think a full tear-down woud be needed just to ensure you get all the broken pieces out.
I have three stubborn lower crank case bolts stuck. I buggered up the heads of these bolts so I must remove the bolt heads (with a drill bit that is slightly larger than the bolt diameter) and then pry open the crank case. Once the crank case is split, I expect to find the remains of the sprag clutch bearings. I have discovered more shrapnel and ball bearings rolling around inside the motor. I'm posting pictures on the Trophy facebook group sometime in the next few days.
The bike is about 90 percent disassembled. Only the forks and nose cone are still on the frame. And since I've gone this far, I'm going to painstakingly take the rest of it apart and renew it from tip to tail. Perform all the maintenance and renewal. Might as well! I'm probably looking at a couple of years of work, going at a leisurely pace. Good thing I got my Bonneville to ride!
Yikes! You will know that bike pretty well when its all over.
I did a version of that on a 76 R75/6,it was a big effort,changing frames,rebuilding what ever came up bad .
Once I finished it and rode it,I realized it was an under braked/poor shifting/slow/ill handling sort of scow.
It taught me about wrenching,good practice.
