Hello TomT and others-
Just thought I'd check back to see any new postings. The bike is just great, and finally, I was able to see the engine videos again.
Because of this thread and my interest in similar engines, I have found and read many interesting sites, and viewed some incredible videos showing home-built motorcycle engines. I thank everyone for the links, photos, videos, suggestions, etc, especially TomT for taking the time to answer everyone's questions.
Continued good luck TomT.

EDIT: Check: "thekneelslider.com" website for some monster engines mounted on bikes! NSU 2000cc single-cylinder engine, gigantic V-twin engines, etc. Interesting concepts.... I guess.
