Brake and clutch fluid should be replaced about once a year

Even once every two years is okay!
Engine oil, brake and clutch fluid, and coolant are essential fluids that we definitely want to keep on top of.

If fluid sits too long, it can become jelly-like and promote rust.
Coolant also cycles between room temperature and near boiling, and dirt tends to settle in the lower areas.
If that lower area is an iron water pipe, it can trigger corrosion and eventually lead to holes, so caution is needed.

When it comes to spark plugs, it’s JR8B. Replacing with a new one

It doesn’t seem quite crisp.
Let’s reset it once and see how it goes!

We’ll replace the air filter with the genuine part.

The titanium full exhaust with excellent serviceability is the best

It slides out and inserts smoothly—the feel is excellent.
You really can’t tell how good or bad the muffler serviceability is until you actually remove and install it yourself.

Engine oil change. Once in a while, let’s get a new drain bolt too

The drain bolt is a part you can freely replace if it looks dirty.
It doesn’t cost much, and having a clean bolt just feels more satisfying.

Crisp! And complete~
