I think on the ice racer I got the motor out in 20 minutes

.. it was a very stripped bike
Things that help; Spigot mount headers ( 4 bolts to loosen, one to remove) Carbs with pods, or Webers (easy on & off)
In those days I could lift a motor out myself easy, lean on the frame with a pad under my chest, and put it on a box beside frame when out, ...worked in the woods packing a 29 lb saw and gear all day back then.
hDid one a year or two back, could barely get it out, pinced my finger.. felt like such a girlll....
