Hello everyone, newbie here as of today. I am designing and fabricating my own frame for a '73 CB350F powered (with turbo) "land speed" bike. If any of you out there can help, or direct me, I would be grateful, as I have been unable to locate specifications. I don't have the entire donor bike/frame. I need the steering head (neck) tube I.D., O.D (press-fit at bearing races) and length. I can then purchase a piece of tube and build the rest. I DO own the lower triple tree, forks, front wheel and axle. As of now I am missing the upper tree (fork crown), all races and bearings. Thank you in advance.
