  4. 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. My friend had it in pieces, and I have recently really dove into it. It doesn't have carbs, so I need to locate those, and replace...

    Project Logs
    Hi everyone, I thought I had better post some pics and details of my cb400t rebuild. It has taken 6 months so far and been enjoyable to turn a rusty POS into something nice, although I think I will start with something cleaner for my next build. Everything has been cleaned/rebuilt/sand or soda...

  13. 78 CB400TII – First Bike (photos and fun)

    Project Logs
    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...

  16. 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...
  17. Oil leak from (possibly) neutral safety switch?

    Engine Discussion
    Good afternoon folks! I am new to the twin world and I picked an admittedly leak prone bike (according to most mechanics I've spoken to). I have a 1979 CB400t II and I have it running like a top and safely at this point (again, thanks to a great mechanic). Next on my list is to start tackling...
  18. '78 CB400T Piston Ring Placement

    Engine Discussion
    Hey all! So, now I'm rebuilding the top end of my '78 CB400TII. I have new piston rings, but I can't figure out which place to put the top two rings. One is plain silver, the other is black with the surface that contacts the cylinder silver. The manual says that one of them should be tapered...
  19. CB400T Mystery Part

    Engine Discussion
    Hey all! So, I'm installing the crankshaft in my '78 CB400T. Got back together up to the main bearing cap, but I have a part left over (terrifying, I know). I don't remember where it's from, can't find it on any of the exploded parts diagrams, and don't see a place where it would fit. I'm...
  20. '78 CB400T Big End Bearings

    Engine Discussion
    Hey all! I need to get the crankshaft and connecting rods of my 1978 CB400T ground/resized. However, I have heard that Honda only made standard sized big end bearings, so if there is ever any damage to the conrods or crank, the parts would need to be replaced. Is this true? If not, where could...
