    Engine Discussion
    Two years ago my friend and I rebuilt my 70’ CB450 engine with the bottom end of 68’ CL450. It was riding pretty well for about a year (for the exception of some power loss). But about a year ago I went for a ride and while riding in 5th on the highway, the whole bike jerked like the clutch...

    Parts For Sale
    I have a bunch of parts leftover from a 1974 CB450 build, started off with 3 bikes so lots of leftovers. Would be great to help someone local who needs bits and pieces to complete something they are working on. Some parts have a value but others I’d be willing to unload for next to nothing...
  4. Issues Adjusting Rear Brake Pedal, 67 CB450K0

    Tires, Wheels, and Brakes
    Just replaced the shoes for my rear brake and got the wheel installed back on the bike. After taking the bike off the jack, I noticed that the rear brake pedal had way too much range (~3 inches), so I just turned the adjustment bolt clockwise (in), which solved this problem. The range is now...

  6. '67 CB450K0 - Questions regarding rear brake+wheel bearing replacement

    Tires, Wheels, and Brakes
    Hi, '67 CB450K0 here, replacing my rear brake shoes and rear wheel bearings. Figured they're due for some work. Just have two questions about this. 1) I noticed there seems to be some grease that you can see leaking out of the bearing in one picture and onto the removed brake housing in the...

    Engine Discussion
    Several months ago, I sent the top and bottom case for my '73 CB450 off to be vapor blasted (shout out to RestoCycle). The results are great and all my other parts have now arrived. However, while inspecting everything before beginning assembly I noticed something. I'm sure that the blaster...
  9. Black Bomber Crankshaft

    Miscellaneous Discussion
    Hi all, My bomber needs a new crankshaft, and it seems to be a huge pita to find! I posted on the looking for parts sub already, but I was wondering if anyone here might know where i could try to look for one, as ebay seems to be fairly thin right now. If only the later crankshaft could fit my...

    By far my favorite Honda color. I've had this collection of NOS Candy Gold parts for my 1971 Honda CB450 sitting in my office for the past couple years. They each have their share of "shelf wear" but it will be a beautiful bike if I ever get the time to work on it. The parts came from the US...
