It suddenly got cold today… even though it was summer weather just the other day.
There’s been a lot of rain, and I wonder if the rainy season is approaching soon?
This R1 has already been around for 13 years now… time flies!
I still think bikes from ’98 are the latest thing, you know?

We’ll replace the coolant. When draining the water, I always think, could we do a cleaner job?
That’s what I’m thinking.
When there’s a drain fitting (drain protrusion), you can just slip a hose on it—that’s the racing way!

I’ll come up with a tool that works on anything next time.
When you can keep the work as clean as possible, the cleanup effort drops dramatically.

The radiator cap was fine, so we’ll reuse it.

We topped off the reservoir fluid. When you mark the level after topping it off, you can tell at the next check whether it’s gone down or up.

We lubricated the clutch lever and clutch cable.

We cleaned and lubricated the throttle and cable as well.

We’ll wash the calipers… hmm, they’re clean… that’s great!

A 38mm aluminum piston for single-piston use…
I wonder if I could use it on my CB… there’s definitely potential for a secret tune-up.

The rear axle runout looks good.

We’ll check the wheel bearings.

Hub-side needle roller bearings. Technology has come a long way, hasn’t it? (Though this is from 13 years ago.)

The rear support had a dull finish, so we polished it back to life.


We cleaned the front calipers too.

The front axle is fine too.

We checked the front wheel bearings too.
No issues.


We replaced the brake fluid with Golden Cruiser DOT4.

We changed the engine oil and filter.
Next is a test ride and we’re done.
