  1. Electrical Issues
    Hello, There’s a 1981 cm400 posted local to me for $900. The bike looks nice, has aftermarket headlight, new seat, chopped off stock rear fender with a custom chrome one in its place, however the bike has no spark. It looks like the only readily available part that could be replaced is the...
  2. Frame, Suspension and Steering
    Yo guys I just had a question, my front forks on my 81 cm400a are bent and I had these extra (I wanna say there from a gl500?) forks laying around but I can tell there bigger in diameter and also are dual disk breaks instead of single like the stock forks. I was wondering if I could convert...
  3. Fuel Supply and Carburation
    I recently was gifted a 81 CM400T for my first bike. 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. Can anyone help me with where I could get a new tank that doesn't require a lot of work to make...
  4. Wanted Parts and Bikes
    Must not be rusted thru and must not be a repaired tank that previously rusted thru. Small dent(s) tolerable but not those that look like your crushed grade-school lunchbox or those that became victimized by an ex-girlfriend If still wearing original paint, a later one with wing decals is...

    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...

  7. Miscellaneous Discussion
    Hello y'all First time on this forum. I just picked up my first motorcycle (a 1981 CM 400E) and I want to build a simple ratty bobber out of it. I plan on keeping the stock air box but the exhaust is destroyed on this thing from the mufflers back. I'm planning on simply putting turn downs where...
  8. Project Logs
    I bought almost dead (if not completely) CM400C 1981 for $400. Odometer claim it has 32k miles, but the speedometer cable was broken so I suspect it might be much higher. Quite a big challenge for me as it is my very first project. The goal of this project is: 1) To make it run. 2) To make it...

This year i purchased my 2nd (and 3rd) bike and it's been a challange but a fun one. I live in upstate NY so the riding...

    Just bought a Honda CM400T. Great looking bike. Having trouble getting a UK registration for it from DVLA at the moment, but hope to be out and about soon. Seems smooth. Just sold a Superdream I was very happy with, can't believe the superior build of the 400. Anyone else find the rear...

    I found a cb900 for a good deal but 3rd cylinder is seized. Could a drop a 650 into it with little trouble?
  12. Electrical Discussion
    Hello, First of all sorry in advance for my bad English I'm from Germany and not really into posting on forums :) I have signed up to this forum because I have a weird issue with my Dads '81 CM400T which is really annoying and I don't know how to solve it. After pretty much standing still for...
  13. Fuel Supply and Carburation
    I didn't do a keyword search but figured you guys might be able to help me on the best aftermarket or simply replacement carbs purchasable. What's a good site or seller that would ship to me? I have about 250-300$ to work with and am looking to install it asap. TIA

    Haha well I decided to drive 2 hours to Austin Texas to pick up a bare bones 79 Honda cm400 frame is chopped, doesn’t run, no instrument cluster, leaking forks, no battery the guy converted it into a capacitor. That’s just scratching the surface. I’ve never worked on a bike before but if anyone...
  15. Fuel Supply and Carburation
    So my buddy bought a 81 cm400 custom for cheap, didn’t run. We figured it was carb. So we cleaned the carb and did a rebuild. Starts up fine but revs kinda crappy. First time for both of us rebuilding a carb. When you ride the bike it seems to not have much get up and go with any sort of load on...

    Hello. I am new to the site, but I have already found it helpful. Thanks. I am on my 2nd project bike, 1981 CM400c. It was in fairly good shape and running well, but not maintained or cleaned very well. I am doing a lot of work and painting. Hopefully, I will get it running even better than...
  17. Miscellaneous Discussion
    So I just recently purchased a 1981 CB400. The bike did not have a title when I got it, and being new to honda street bike I took the sellers word. I called my local dmv to make sure it was not reported stolen and it checked out ok. That being said I am having conflicting vin results. My dmv and...
  18. Tires, Wheels, and Brakes
    So, super new to moto wrenching (I've been a bicycle mechanic for years, so I am mechanically inclined, but moto is a whole new bag of worms). Looking to better understand what to look for in buying a stainless braided front brake line. I have no idea what's compatible with what years/models...
  19. Engine Discussion
    Hi Everyone, I have a nice little CM400 that I recently tuned up, adjusted valves, changed gasket and adjusted cam chain tension. I may have made a mistake at some point because it seems that the tensioner bolt went back inside the engine too much and now it is too short to put the nut onto...
