    I go by Lee, I’m from Chicago but currently residing in Atlanta, Ga. I was able to score on a 1981 Honda CM400A a few months ago. Had it since August now. The previous owner that I bought it from had purchased the bike from a guy that he did detailing for. I’ve been using this bike on my commute...
  3. Electrical Issues
    Currently working on a 1981 Honda CM400C cafe racer build. Seems to be an electrical issue where sometimes I go to start the bike and nothing happens. It’s not the battery, I have checked that multiple times. Anyone have any suggestions on what it could be? Anyone know where I can get a brand...

  6. Fuel Supply and Carburation
    Hello all, About a year ago I bought a 1981 Honda CM400C Custom. It was advertised as turned over but did not run, and the seller said it would most likely need a carb cleaning it should be good. Having never ridden a motorcycle or done any kind of mechanic work, I decided to go for it, and it...
  7. Engine Discussion
    So i finally finished visually restoring my honda cm400e and putting on a new gas tank. I got it back together and took it for a short ride and now theres a strange sound in the engine. Whenever I try to start it makes a higher pitched clanking noise, at a moderate pace. I should have taken a...

    Hello everyone! I'm very excited to own my first running vintage motorcycle! The person who sold it had put a lot of work into making it run like a top and while bikes around here are pricey, this one was a fair deal and allowed me budget for the modifications I plan. The first thing I plan to...

    Hello, I have tried to save my 1981 Honda Cm400E's gas tank with gas tank puddy and a gas tank sealant/liner to no avail. I wanted to keep the stock look, but I guess Ill have to give up on that. Do you guys have any recommendations on where to get a new tank, and the dimension of the tank...
  10. Electrical Discussion
    One thing to note before I explain; my ignition is broken so right now it is just a homemade knob where the ignition had been (should have made it more secure when parking on the street, I know). I had my bike parked outside a friend's house, covered with a tarp, and someone tried to steal it. I...
  11. Tires, Wheels, and Brakes
    Just bought an 81' CM400E, and there is a plethora of things I need to fix up on it, but the main issue I am having at the moment is finding a front brake cable. I was wondering if anybody knew where to find one or one that would work or any other tips for this issue. I'm new to motorcycles and...
  12. Tune Up
    I have a 1981 Honda CM400 that turns over but does not start. I'm pretty sure I didn't clean the carb thoroughly enough, but that's beside the point. This bike has been sitting for quite some time (years), and I wanted to know what you all do with old bikes after you get them started; just some...

    Hello, all! My name is Josh and I have a 1981 CM400Custom that I'm restoring. Found it under an old barn that had fallen on top of it. Still in great shape but hasn't been ridden since 1989 (or messed with). I put on a new start solenoid and it will turn over. I'm looking for a CDI module for it...

    Hello I am Ryan. My brother had a 1980 cm400t he left out uncovered for 2 years he put a new battery in it and tried starting it. Gave up and let it sit a bit longer before he decided he was sick of looking at it. He called me and asked if I wanted it. When I got it the motor was seized, carbs...

    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...
  16. 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...
  17. 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...
  18. 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...
  19. Engine Discussion
    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...
