Oil-cooled GSX-R1100K/L 89-90 “Secret Parts List?” Still! Now Available Aftermarket and OEM Parts Roundup

Parts for each model…
I think I understand, but I don’t really.
I think I’m keeping up, but I’m not.

I can’t compete with the owner’s passion…
Please do your own research and teach me.

Axle Shaft/Pivot Shaft(OEM replacement OK)

GSX-R1100K/L Front Axle Shaft 671-03-020

GSX-R1100K/L Rear Axle Shaft 671-03-014

Rest assured even if the shaft is discontinued! Electroless nickel plating makes it shiny and nice (*´ω｀*)

“Forward 30mm Down 20mm” – The only? comfortable position step kit

Aftermarket steps tend to be“STD positionmoreBACKandUP“
Everyone has different leg length and preferences…

The only? forward and down step is really great. *Of course, it depends on preference.

The construction is simpleand very cool.

This is an image of foot placement on the pedal and standing on tiptoes.
*By the way, I have long legs, so please note.

Try to imagine the positional relationship from the pivot.
If your feet feel tight, I think you’ll feel more comfortable.

Got it… “Forward 30mm Down 20mm”is the result.

Bito R&D GSX-R1100 Oil-cooled ’89-92 Riding Step&
It’s great that it works up to the final model.

Is the Yoshimura engine cover hard to crack?

At KEY ON, theoil pressure lamp (red lamp) will no longer light up.

Somehow, I have the impression that the Yoshimura cover is less likely to crack in a crash.
As a replacement and preventive measure, it’s a helpful part.

Ignition countermeasures are “Watanabe” and “Plasma Booster”

If the igniter or coil condition is not good? If there’s a possibility, the all-in-one replacement option is Watanabe
Watanabe Full Power Kit GSX-R1100K-N Part No. 00407
*Watanabe and Plasma Booster can be used together.
You’ll be able to feel the change in the flow from Plasma Booster to Watanabe.

*Please note that Watanabe is a consumable item.

A bit niche Plasma Booster SB512400S

Unless you can turn it ON/OFF, it’s hard to feel the difference? is the thing.
You might think nothing has changedbut it subtly works.

Improved starting and smoothnessis something I really love.
Howeverthe cost-effectiveness is thinso caution is needed…
*I have installed them on all my personally owned vehicles.

Brake discs are set with Sunstar (*´ω｀*)

Back in the day there were“Custom/S-type/M-type/Neo-classic”four types
but now“M-type” ONLYhas become… Too bad.
Since there are left and right, buy 2.

Compatible with Suzuki pitch. Rear brake disc

“GSX-R era rear disc 6mm” LR023 5mm installation compatible and usable.
The calipercenter will be slightly misalignedso please check the actual vehicle and adjust.

Long… to be continued
