Katana is 1000! GSX1000S Inspection – Rear Disc Replacement and More

A GSX1000S fully equipped with dry carbon and Yoshimura parts.
Calling it a 1000 is pretty niche, right?

The banana frame is real steel tubing too… We’ll replace the rear disc and caliper.

First, we’ll install aluminum pistons in the GS1200SS rear caliper.

It’s a new caliper, but we won’t use the seals that came with it—we’ll use brand new ones instead.
* I know, sounds cryptic, right?

The OEM pads came with pad shims… kind of like deadstock.

They brought it in with an A+B=as-is setup.

One spot was stubborn, and when I worked at it, the helicoil started to come out…
I had a bad feeling about it, but we got lucky.

The compatibility between helicoils and thread locker is very tricky. Should I apply thread locker directly to the helicoil itself?

I use helicoils without the slot.

This is definitely convenient.

We converted the bolt diameter from 10φ to 8φ and made it with a flange since the width didn’t match.
The material is SUS304. With this thin wall, it might get crushed even at 17 or 75, so just to be safe…

We wrapped up the installation with a slight trim.

It looks much cleaner now. Great! (ΦωΦ)
