Guys, I don't know if my helmet is big enough for my head after Sam's post.
I am pretty sure you have a 1966 model. I will assum that your frame/engine number is going to be a 101xxxx number. They started with 1000046 and up to the 102xxxx. What is surprising is that you won't find any production numbers for each year and a 1965 may be titled as a 1967 because they were done in the year sold back then. All are K0's from 1965 through the 1967 model year. The K1 was a 1968 model.
What you have is a 4 speed. You can tell by the number of screws holding the sprocket cover on - 4 screws = 4 speeds and 5 screws = 5 speed (1968 K1 and up). Do not be affraid to restore this bike. It has a lot of parts and I will absolutely confirm that doing one in 2,3, 5 years down the road will be near impossible. I sourced from 13 countries and had a huge network of friends and businesses helping and it took me almost 1 year. There are actually 6 parts on the bike that are not available from anyone/anywhere. Those are the seat hinges and the two front fork trims. I had to commission a tool maker to make a stamp press and do 100 of the hinges, then 30 pairs of the fork trims. I sold all but 2 sets, re-couped all my money within 2 weeks! The Black Bomber fans are fantastic folks.
This is and will likely be the most valuable and most rewarding bike you will get to own. Out of 30+ restorations, it is certainly the most memorable, the most difficult (parts wise) and in my opinion will only get better with age. It won't be cheap. Nice with good parts = $4,000. Very nice with near perfect parts = $10,000, 90% or more NOS and absolutely busting the budget wide-open - $20,000 and 300+ hours of labor and fun.
What ever you decide, don't cut it up, don't cafe it - buy a later model and do that. These belong in the history books and in places for people to enjoy for years to come. That shifter on the bike is the original, hollow factory part. That is like impossible to find and could cost you $200-300 for another one like it. Be carefuly buying new parts - OEM parts from Honda will work, but you may be throwing a valuable and rare part away. I could talk for hours on what makes a Bomber different and unique. You'll be the same way once you've finished it. Take your time and enjoy that cylinder head, those front forks with some wild progressive dual springs inside. The engineering on this one has so many neat features that were never again used. - The cylinder head is aluminum, but they cast in iron valve seats and hemisperical chambers. The valves are controlled by torsion bars - not springs to give airflow path the shortest distand possible. When you see one up close - you're gonna smile and wil ask yourself "can I put this back together?". I have told many folks that the Black Bomber has more parts in the cylinderhead than most other bikes have in their entire engine.
