Converting Inazuma to GSF1200?? GSX1200S Oil-Cooled Inazuma Katana BST36 Installation Swingarm Overhaul Fork Overhaul & Bottom Case Modification

The docile Inazuma 1200’s true nature is…

So what about the Inazuma’s original? Boom! Let’s unleash the performance! I want to bring it out!
Riding that everyone might have thought about…

With the air cleaner box! Installing BST36 (*’ω’*)


Failure is not an option. That’s why preparation is crucial (*´ω`*)

I bought air cleaner boxes for both the GSF1200 and Inazuma 1200.
I wanted to know the pitch and diameter & do a trial fitting as well.

Oh right, that’s right…
The GSF1200’s BST36 funnel side was egg-shaped.

Well, since the other side is rubber, I’ll go with round!

I’ll research the numbers and visualize them on a board (*’ω’*)

I realize here that it’s not actually symmetrical left and right… The air cleaner box is split-type, so that’s natural.


Thinking about how to remove this cleanly and easily… took several hours

After thinking about it all night, I came up with an idea.

The plan: attach a sharpened pipe to a grooving cutter and go at it.

As expected… the heat doesn’t transfer at all…
So I’ll heat it up with a gas burner and melt it.

Viva! New York? (*’ω’*)

It’s a super analog approach, but better than grinding.
It was surprisingly effective~

This is a practice one but it turned out well. *I’m working with Scotch tape.

Can the dummy air cleaner box be mounted securely???

Perfect Cinderella fit! I’m relieved~

Now for the real deal, let’s go! *In-vehicle state

I drilled it out like this (*´ω`*)
I filled in the holes for the plate fixing.

Deeply moving! Inazuma 1200 with BST36

Perfect! ♪ I want to start the engine soon, but… the throttle cable…

Also, I accidentally forgot to order the bands…

If it runs normally like this, that would be great. I’m hopeful~
