  1. Kickstart not returning CB400t/hawk

    Mechanical Issues
    Hi, I am new to this site and also kind of new to 'bike mechanics'. Just bought a project bike - 1989 Honda CB400t/hawk. In the videos it ran great but the prev owner informed me that the Kickstart wasn't returning. So I opened the Kickstart case cover and with it open the Kickstart returns...

    Hi all! Glad to say I am a member of the Honda twin family. This forum was super helpful when trying to work out if I should pick up this bike or not. This is my first bike. It's a 1980 CB400T with 3600 km on the odometer(!). Third (post-rebirth) owner. Guy I bought it from got it from the...
  3. Fork rebuild - what to buy?

    Frame, Suspension and Steering
    Hi everyone, When I bought my bike (81 CB400T Nighthawk) the forks had some light oil streaking (but no pitting or scratches) so I'm wondering exactly what wearable parts I should be replacing when I rebuild them (also planning to repaint the bottoms). There doesn't seem to be any full fork...
  4. ‘78 Cb400t, no spark, stator issue?

    Electrical Discussion
    Hi there, So I picked up a Cb400t that hasn’t been registered for 9 years. Guy said he dumped it once because of the sticky drum brake and was too scared to drive it again. It doesn’t have a battery, so I attached an external 12v battery directly to the leads. Electric start fires, but no spark...

  8. CB400T - Cam chain not keeping tension?

    Engine Discussion
    Hey all! I'm running into a strange issue and I'm wondering if anyone has any ideas. It seems like cam chain on my 78 CB400T is losing tension after only about 20 miles of riding. I adjusted the valves and cam chain in that order following the FSM this spring. When I did the valves, I pulled...

    Member Introductions
    Hey everyone, I recently was given a 1978 CB400t by a friend who didn't have time to work on it. I am a mechanic for a golf course, so I took it on as a fun project.

Everything has been cleaned/rebuilt/sand or soda...

    I don’t have a lot of technical and mechanical experience, so I wasn’t sure about making a Project Log and having it end up being a public record of oh whoopses, but I’ve already learned a lot from reading other threads, and I think it would be nice to have an inventory of the things I end up...

  20. Carburetor Identification and question for 1978 Cb400 Hawk

    Fuel Supply and Carburation
    I recently traded some art for a 1978 Honda Hawk CB400 (TI - I think). It has been sitting for years, and much of the bike was disassembled in a Tubberware container, along with water, thus much rust and corrosion. Upon looking into the carburetion, taking apart what I could manage through the...
