Okay, so I’ve been meaning to get my hands dirty with a classic bike for a while, and I finally took the plunge with a Honda CB450E. It wasn’t exactly showroom condition, more like “barn find fresh,” but that’s part of the charm, right?

First thing I did was just assess what I was working with. The bike was complete, which was a huge plus, but the engine was seized, there was rust everywhere, and the wiring looked like a rat’s nest. I knew this was going to be a project, and I was kind of excited about it.
Getting Started
I started by tearing down the engine. It was completely gunked up inside. Years of old oil and who-knows-what-else had turned into a sticky mess. I spent hours soaking parts in solvent, scrubbing, and scraping. I even had to use a heat gun to loosen some of the really stubborn bolts.
- Carburetors: These were a nightmare. I completely disassembled them, cleaned every jet and passage, and replaced all the gaskets and seals.
- Cylinders: I had to hone the cylinders to get rid of the rust and get them smooth again.
- Pistons: I cleaned them, Checked and changed the piston rings.
I had to take time to clean it up. Used a bunch of different rust removers, and even some home remedies I found online (vinegar works wonders, by the way). After tons of elbow grease, I got most of the frame and other parts looking pretty decent.
The Electrical Gremlins
The wiring was a whole other beast. I’m not an electrician, I am a newbie, so this was a steep learning curve. I got myself a wiring diagram for the CB450E and just started tracing wires. I found a bunch of frayed wires, corroded connectors, and some really questionable previous repairs. I ended up replacing a good chunk of the wiring harness and all of the connectors.
Putting It All Back Together
Once I had all the parts cleaned, repaired, or replaced, it was time for reassembly. This was probably the most satisfying part. Seeing the bike slowly come back to life was amazing. I made sure to torque everything to spec and double-checked all my work. It’s all about patience.

Finally, the moment of truth. I put some fresh gas in the tank, turned the key, and hit the starter. After a few cranks, she sputtered to life! It wasn’t perfect, there was some tuning to do, but it ran! I took it for a short spin around the block, and I couldn’t stop grinning. I Still need to do some fine-tuning and cosmetic work, but it’s rideable!
This whole project has been a massive learning experience. I’ve learned so much about motorcycle mechanics, and I’ve gained a whole new appreciation for these old bikes. It’s been challenging, frustrating at times, but ultimately incredibly rewarding. I can’t wait to get it fully dialed in and enjoy some rides on this classic machine.
