  1. 1978 CB400t II Rebuild

    Engine Discussion
    Hi! I'm totally new to this world of motorcycle building/restoring. This last summer I picked up a '78 Hawk with the intent of fixing it up over the winter - alas, winter is almost over and I'm still working on the engine rebuild. Anyway, a buddy and I (both in college) intend to finish the...
  2. CB 400 TII Hawk throttle cable re-routing issue

    Fuel Supply and Carburation
    So I had ACL reconstruction surgery a couple weeks ago and since I won't be able to ride for awhile I've been doing some TLC on the Hawk. I swapped stock handlebars to ones with lower rise (+4" rise to 2.4" rise) and found that not only do the long cables bind, but the PO had criss-crossed the...

    Miscellaneous Discussion
    Hi all, I’m looking for some help. I'm trying to find the right part for a 1978 CB400TII. I hope this is the appropriate form section for exhaust questions. When I purchased the bike, the PO talked me through the work that he had done already, and the things he hadn't gotten to. He mentioned...
  4. 1978 Honda CB400T Electrical problems

    Electrical Discussion
    Hey there, so I'm pretty new to the world of restoration, and I know next to nothing about electrical systems.

    Hello Everyone! First off, I have been reading this forum for over a year now and have gained a wealth of information! Thank you all very much! Last summer I broke one of my cylinder head bolts and did a terrible job drilling it out. Since then I have had an engine stutter while accelerating or...
  7. CB400TII engine fades at higher revs

    Fuel Supply and Carburation
    I have a 1978 Hawk CB400TII. This is a recent purchase and was running very poorly, but could reach about 50-55mph when pushed. I took off the carburetor and did a thorough overhaul of it but I didn't replace any jets. I blew through everything, set the floats, put all the springs back in the...

    Project Logs
    So I just picked up my first project, a ’78 Hawk 400. I grew up racing dirtbikes in New England but this is my first road bike and my first project. After hiding in the shadows, seeing all the awesome stuff everyone else has been doing on these forums I decided to keep a log of everything I do...
  9. '78 CB400TII Rear brake pedal return spring question

    Tires, Wheels, and Brakes
    Okay, my bike came in several boxes, and I'm trying to reassemble because the weather is getting warm. I found the rear brake pedal return spring, but I can't figure out where the other end goes. One end hooks to the pedal, in the same hole as the stop light switch spring, but the other end...
