I bought this 1976 CB400f from Greg Roberts of Tennessee about 3 years ago, it had been in his family since it was purchased new (uncle and brother were previous owners). Except for a battery, a solenoid, and right hand kill/starter switch, it was completely original down to the dry rotted but functional tires. I replaced the battery, tires (Bridgestone Battlax), chain, and sprockets. I took a job 18 months ago in Iraq as a contract firefighter and did not have time to drain the fuel/carbs. So when I finally got home 3 weeks ago it was job #1, which was greatly aided by tips found here. Once the battery was charged I found my starter button was DOA, but at least I finally got the headlight to work. So a jump of the solenoid or quick kick and she's purrs like a kitten. I cleaned up the frame when I had the tank off. Future projects: I have a broken tab on the right side cover, there's a little surface rust on the inside of the fenders, and that problematic starter switch. But the paint is still glossy, the original decals are in good shape, the complete exhaust is rust free, and the wheels look like new. Thanks for all the tips and suggestions.
