Oil-Cooled GSX-R1100K Gradually Growing on Me – Oil-Cooled Maintenance and Key Set Replacement

The most popular K-type

• Short wheelbase
• Rear suspension upper mount is detachable
• 2-valve single rocker
• Upright fork
• Front and rear 17-inch (and surprisingly rear 4.5)
• Lots of compatibility with 1200-series

Back in the day,
I don’t think it was the most popular.

Generally, what was preferred was
the early models or M/N-type, if I remember correctly.
In the heyday of custom parts swapping,
countless R models were stripped of their suspension and discarded
by the Katana crowd.

First, let’s replace the key set.

There are so many beautiful bikes
that I get tired of masking every time.

I make sure not to wear clothes with buttons or zippers
to avoid this.

The owner brought in a used item in good condition,
so we’ll swap it in here.

First, we’ll replace the fuel tank cap.
There’s accumulated dirt around it,

Vuplex!
I bought this as a Plexus substitute before
and have used it extensively.

It’s like cleaning combined with shine enhancement
– parts cleaner alone doesn’t quite cut it,
and water is hard to rinse off,
so this is really effective in those situations.

We’re replacing the seat lock,
so we’ll remove the tandem step plate.

We wet-blasted it before,
but the matte finish gets dirty easily,
so this is a handy item for quick cleaning.

Engine conditioner is
really useful stuff.

You can just spray and wipe,
but this time I used a secret toothbrush.

Nano Toothbrush Soft 6-Piece Set

What’s good about this is
“no splashing,”
“cleans even the tiniest holes perfectly.”

Since it’s just a toothbrush,
it doesn’t last forever,
but it holds up surprisingly well even used this way.
It won’t give up in 1-2 months.

I’ll give it a proper review soon!

Oh, and
for those whose toothbrushes spread out quickly!
“This one doesn’t spread at all” = long-lasting
because the key is the quantity and softness.

We also cleaned up the neck area nicely!

We’re replacing the key cylinder.
It was put together pretty haphazardly,
so I made a spacer for it.

Washer adjustment is important in this spot,

Replacing the speedometer gear & cable (NEW).

New cables are really soft,
so it’s worth replacing them while parts are still available.

The reason is
Suzuki’s design is quirky,
and reproductions are hard to come by.

Maybe that’s a downside of their original-design culture.

I inspected the new gear inside,
and since the meter-side gear is plastic,
I applied silicone grease.
