Finally got the motor in. This entailed some finishing layer coats of paint on the cases (used brake caliper paint, works awesome). Thanks for the tip Lee at onthepiperacing
I also had to complete the install of the new bearings, sleeves, etc. into the swingarm since the bolt runs through the engine cases.

The new dustcaps seemed huge and were creating a clearance issue so I had to grind 1/2 of the cup down so it would clear.
Sorry for the blurry cellphone pics but it was late and didn’t have the camera handy.

Below you can see the tight squeeze and custom dust seal needed:
