Perfect custom feel. Z1000MK2 rear pad replacement, fluid/engine oil change and more

This is a continuation of everyone’s favorite Z1000MK2.
The rear brake disc has arrived, so I’m going to install it quickly.

I love how the brake disc has so many holes in it (*´ω｀*)

Kawasaki motorcycles really have an abundance of aftermarket parts, which is great.
I feel the difference in market size every day.

Let me check the component configuration.
Looking closely, the rear caliper center is pretty extreme.
That’s Kawasaki quality for you! Even with this, it works without any problems—a reassuring finish.

It’s a good idea to measure the brake disc before replacing it.
So much time has passed that nobody even knows what’s original anymore.
Simply replacing parts can cause problems.
Check everything carefully to ensure smooth and safe operation.

I’ll clean the wheel-side threads thoroughly.
Leftover thread locker can make tightening difficult.
I want to clean it so it inserts smoothly and tighten it with the proper torque.

The 290φ TR-11HZ looks so cool (*´ω｀*)

Oh wow, that looks really nice.
Brake discs with holes really are cool.
Functionally, they’re lighter and have better cleaning effects.

I thought I’d need to adjust the position quite a bit, but…
That’s Sunstar for you—one-shot win! Three bonus tiles!

I’m also overhauling the rear caliper at the same time

I cleaned up the corroded areas with wet blasting.
It really feels good when individual parts are clean.
Once assembled, it won’t be visible, but somehow the feeling lingers.

The pistons were in good enough condition this time, so I reused them.
The piston outer diameter is a bit of an odd number.

I’m forcing the bleeder to be titanium.
I don’t usually use different materials for bolts, but this is one place I won’t compromise.
Iron will rust no matter what you do because of the fluid.

It looks sleek and doesn’t rust, so it’s reassuring.

One concern eliminated (*´ω｀*)

With the new rear disc and pads, the contact surface is now properly seated.
The rear caliper center is also perfect,
so brake pad wear should be more even.

And by overhauling the rear caliper,
the rear brake feel has become much more solid.

Now the rear brake is finally in normal condition.
The riding experience should be even more enjoyable.

Let me do a quick check.

I made a little modification on my own.
The beta pin isn’t really necessary, but since there’s space,
I installed a Honda OEM one.

The lock nut is Honda OEM M18-1.5 90305-MB4-003

94252-16100. With this part number, changing the “●●” digits in 94252-●●100 gives you various sizes.
Though there are only about 5 or 6 options.

Using the right diameter adds a nice touch.
Cotter pins are inefficient and annoying to remove, so it’s better to eliminate them if possible.

If you use a lock nut instead, “No pin needed for inspection” is fine.

The rear master cylinder hits the side cover issue.
I ground down the rear master cylinder quite a bit (with a belt sander).
The bolt sticks out where I ground it, so I cut it.

Hmm… the emblem speed nut is missing.
Is it double-sided tape?

I’ve been thinking lately, “If you notice it, you lose?”
Let me check on it. Hopefully I can finish tomorrow…
