Welcome Kent - appears to be a KO indeed. My KO is also a 1/70 build with 102***** numbers. Very sought after bike, however, as you know yours had MANY modifications over the years. I hope the previous owner gave you a big box of parts with it including title. How much money are you planning on sticking into it to get it back to original? A quick look at the pics - missing are the correct carbs (or keep those carbs), fork ears, forks, chain guard, fenders, handlebar switches, blinkers, center stand, recessed ignition switch with bracket and air box. (And that is just a quick look).
Where is the master cylinder and caliper? And the front tire is on backwards in looking at the location of that front brake disc (should be on the left side). Not to mention the HM300 exhaust. Not saying you need all this stuff to get it on the road, but if you want it back to original...your best spot for parts is eBay or try the "wanted" section on this board. As far as a manual go with the Honda service manual. They pop up on eBay too. Good luck with your project and let us know how you come out.
