Alright, so I finally got my hands on a 2001 Honda XR100. It was a bit rough around the edges, but I saw the potential. My goal? Get this little beast running like a champ and maybe even give it a bit of a facelift.

First Look and Assessment
First things first, I gave it a good once-over. I checked the obvious stuff: tires, brakes, chain, sprockets. The tires were pretty worn, and the chain was looking a little rusty. Brakes seemed okay, but I knew I’d need to bleed them later just to be sure.
- Tires: Worn out. Needed replacing.
- Chain: Rusty. Needed cleaning and lubing, or maybe even replacing.
- Brakes: Seemed functional, but needed a closer look.
- Sprockets: Show sign of wear, better replace it along with the chain.
Getting Down to Business
The biggest issue was that it wouldn’t start consistently. Sometimes it would fire up, other times it would just crank and crank. Classic carburetor problem, I figured. So, I pulled the carb off. It was pretty gunked up, as I expected. I took it apart, soaked all the jets and passages in carb cleaner, and blew everything out with compressed air. Made sure everything was squeaky clean.
While I had the carb off, I also checked the air filter. It was filthy, so I replaced it with a new one. Gotta let that engine breathe!
Putting It Back Together
After the carb was clean and reassembled, I put everything back together. I made sure all the hoses were connected properly and the throttle cable had the right amount of slack. Then came the moment of truth.
The Test Run
I turned the fuel petcock on, gave it a few kicks, and… it fired right up! It idled smoothly, and the throttle response was much better. Success! I took it for a short ride around the yard, and it felt great. No more sputtering or hesitation.

Next Steps
I have replaced the old tires with new ones, also the chain and the sprockets. I bled the brake for more safety concern.
So, there’s still more I want to do. I might repaint the plastics to give it a fresher look, and I’m thinking about adding some new grips. But for now, I’m just happy to have it running well. It’s a fun little bike, and I’m looking forward to getting more time on it.
