    Hello everyone! The problem: My current mufflers, OEM, are beat to hell and full of holes. Loud as heck! What I'm looking for: I'd like to replace them with some new ones that connect directly into the power chamber as is. Ideally, quiet mufflers. I've done some digging, and found a bunch of...
  4. Frame, Suspension and Steering
    Hey dudes, I'm new around here. I come looking for an answer to a question I have. The handlebar/steering bushings in my CM400T are way too soft. I replaced them with OEM rubber bushings and still too soft for me. I have the dimensions of the bushings, but where should I look for polyurethane...

Its in great condition but the tank is filled with rust and there is a ton of holes and poor repair jobs all along the bottom of the tank seams.

    Hi everyone, This is my first post here. I recently bought a 1981 CM400T. However, I've hit a massive roadblock and may now have a lemon on my hands. When I was attempting to change the oil filter, I found that the bolt hole for the filter and cover assembly is totally stripped, probably...

  8. Mechanical Issues
    Hello All, I have a 1980 Honda CM400T and I just took the engine apart to replace all the gaskets. After reassembling the engine, I got to the last portion of tightening down the piston cover bolts. (12 & 10 in the image provided) They require a torque wrench, but I stupidly decided to tighten...

    Hello, smarter individuals than I. I picked up an 1980 CM400T about a year and a half ago and after a long time of putting it off, I am finally ready to fix it up.

    Hey, I have a 1981 Honda CM400T, i hadnt run it for about 2 weeks (just busy) then a few days ago went to start it and nothing. I push the starter button and not a single sound is made, no turning over, no solenoid click, but the headlight dims as well as ignition lights. I am able to bump...

    Head gasket is leaking and the leak is accelerating to the point where I can't ignore it any more. Maybe the gasket between the cylinder and the crankcase, too. I want to replace those, and I figure if I start pulling gaskets off I gotta put all new ones in when I put it back together. I do have...

    Hi all, recently traded my 1980 CB250 Superdream for a similar-aged CM400T. I like the styling, the quality of the build and the extra cc (obviously). Seems to start very easily, which was the main reason I wanted to change. Removed all the luggage clutter (panniers, rear luggage holder and...
