1976 Honda CB

I have a 1976 Honda CB 750 project bike. I bought this bike in 1993. I ran it for a couple of years and decided to do a tune up and one of the spark plugs broke off and then we put in a helicoil and that is about as far as I got. I ended up moving and just never really got back to working on it again. It has some customization done to it. Longer front forks, different handle bars. I laid it down once sitting still at an intersection with wet sand under me. The seat does have spots where the seams is coming loose. Has new tire on back. I think all the parts are in the box. The front caliper is locked up also.
