I recently got to look over a 650 bottom half that has been in storage for Decades . The crank had the alternator section missing. the normal engine breather was properly plugged . The cam was on needle rollers with oil feed at the end , The flywheel looked small . There were no normal engine numbers ,just a tiny unreadable 3 digit mark. The cam looked like it had a longer duration than std. No breathing method to be seen , No extra holes in timing side. Seems likely a factory race engine , Were there many 650 factory non proddy race bikes though ?? Dont remember reading about them.
