    Hey all, I recently bought my first bike -- a 1982 Honda CM450C -- and have been lurking in the shadows on the forums for restoration inspiration, troubleshooting, and general knowledge. I figured I'd finally join in on the fun. I love to learn and there's no better way than by getting my...

    Member Introductions
    Good morning all...Greetings from Boston. A friend was moving and had already called the trash collector to come get this one. He turned it off and parked it 5 years ago under an awning and barely threw a tarp over it. But, it's now mine (Title in hand.) All the parts were there, I just...

    Hello, I just picked up this bike last week ago. The lights were working and now they are not. What happens is as follows.

  7. 82 CM450c rehab: sludgy forks and mystery washers

    Project Logs
    Feeling a bit discouraged/intimidated by all work yet to be done, so thought I would post a re-cap of everything that's been worked on the last month or so I've had the bike. So first things first, new battery, new spark plugs (old ones were BLACK), drained the old gas, added seafoam into the...
  8. First motorcycle, 1982 Honda CM450c in Alberta, Canada

    Member Introductions
    I rode dirtbikes as a kid, and decided this was the summer I was going to get my motorcycle license. I knew I wanted an 80's Honda, and when I saw this 1982 Honda CM450c on Kijiji, I picked it up. It is pretty much stock parts, but generally neglected, although running. There's a lot of dings...
  9. 1982 Honda CM450C left engine cover cracked, gear shifter bent up.

    Engine Discussion
    Hi, I am a new rider and this is my first bike. All was going well until I hit a pothole on a left turn last week and laid the bike down. The left side got pretty messed up and I am hoping I can fix it. The problem is I am no mechanic. Currently the bike runs and drives. Also it can get up into...
  10. Cm450C proper Idle and carb sync

    Fuel Supply and Carburation
    Hey everyone, I have been babying my cm450c with over 200k miles on it for the last 2 weeks because I'm afraid I'll mess it up. Today it scared me. I let it warm up for 5 minutes (I think this is the problem, help me confirm) then pushed the choke in and let it idle for a bit (few seconds...
  11. 1982 Honda CM 450 Custom - Spark Issues?

    Engine Discussion
    Hello everyone! I just recently purchased my first project bike (a 1982 Honda CM 450 C) that up until recently ran pretty well for its age. I am a novice as far as mechanics go but I am trying to stay ahead of the learning curve. I think it could be a spark problem because the bike will...
  12. '82 CM450C Rebuilt a clutch, and now it won't disengage... Reassembled incorrectly?

    Engine Discussion
    ...Just realized I had posted this in the wrong section earlier.... Whoops! Hey folks, I think I need to enlist some Honda expert help. I bought a 1982 CM450C for my girlfriend that had a broken shifter arm for a good price, and figured it would make a neat restoration project. So I get the...

    Frame, Suspension and Steering
    Hello All! My first bike which I received as a Christmas gift 2 years ago is an '82 CM450C with a whole 2500KM on the original engine :) I'm very happy with this bike. I'm looking to add saddlebags and am a safety oriented lady. I don't wish to throw on saddlebags without some sort of...
