Okay, here’s my experience working with my 2014 Kawasaki Ninja 300, told in a casual, blog-style format:

So, I got my hands on this 2014 Ninja 300 a while back. It wasn’t exactly pristine, needed some love, you know? I figured it’d be a fun project, something to tinker with in my spare time. I’ve always liked getting my hands dirty, and bikes are just cool.
First Look and Assessment
First thing I did was give it a good once-over. Checked the basics: tires, brakes, chain, sprockets. The tires were pretty worn, and the chain looked like it hadn’t seen a drop of lube in ages. Brakes felt okay, but I knew I’d want to bleed them just to be sure. Cosmetically, there were some scratches and scuffs, nothing major, but definitely showed its age.
Getting to Work
Oil Change: Started with the obvious – an oil change. Drained the old stuff, which was pretty dark. Replaced the oil filter, too. Pretty straightforward, just made sure to use the right oil weight and not overfill it. I’m no mechanic, but YouTube is your best friend for this stuff!
Chain and Sprockets: This was a bit more involved. I decided to replace both the chain and the sprockets, since they were both showing wear. Getting the old chain off was a pain, had to use a chain breaker tool. Putting the new one on was a bit tricky, too, making sure the master link was properly secured. Took my time, double-checked everything.
- Took off the old chain.
- Removed the old sprockets.
- Cleaned the area real good.
- Installed new sprockets.
- Put on the new chain, making sure that master link was good.
Tires: I opted to have a shop handle the tire change. I don’t have the equipment or experience to do that myself, and I didn’t want to mess it up. They balanced them too, which is important.

Brakes: I bled the brakes myself. Got a little brake bleeding kit, which made it pretty easy. Just followed the instructions, made sure to get all the air bubbles out. The lever felt much firmer after that.
Cleaning and Polishing
Once the mechanical stuff was sorted, I spent some time cleaning it up. Used some soapy water, a good bike cleaner, and a lot of elbow grease. Got rid of a lot of the grime and dirt. I even polished some of the metal bits to make them shine a bit more.
The Result
After all that, the Ninja 300 was running and looking a lot better. It wasn’t perfect, but it was a huge improvement. I learned a lot in the process, and it was really satisfying to bring it back to life. It’s a fun little bike to ride, and I’m glad I took the time to work on it.
I’m thinking to do some modification for it later, maybe next year. I will keep updating, if I really did it.
