Kawasaki GPZ900R OEM HACK
We'd like to introduce you to the passionate story of "ninnin", a GPZ900R rider, from the Webike community's "Moto Hack" campaign!
As a GPZ900R owner, he can tell us how to use the OEM parts on GPZ900R!
A brief self-introduction
Introduction of my motorcycle
Beloved motorcycle: KAWASAKI GPZ900R A12 (1999 expression domestic specification)
How long have you been riding it: I bought it used in 2009, and it will be 11 years old in 2020.
Motivation: I used to ride the same GPZ in the past and wanted to ride it again, but after it fell out of the catalog, I decided to buy a new motorcycle because I thought I was going to run out of good quality balls. At the time, I was looking for balls and bought them for about 550,000 yen with about 12,000 km of mileage.
How to enjoy your everyday motorcycle
Motorcycle History: I got my license in my first year of college and I've been an active for about 30 years.
How to enjoy: I mainly do touring and camping touring. It's fun to wash down the mountain passes on the lower roads and take a hot spring. Long tours with a load of camping gear are great. (I'd love to go back to Hokkaido, Kyushu, and Shikoku!
Annual mileage: about 2,000-3,000km and I'm still raising my child, so I haven't been able to drive the distance.
A brief description of this HACK
This is a way to lighten the heavy clutch, which is hard on the left hand in the second half of touring, and at the end of the touring, it's a bit of a chore to hold the clutch. The clutch master for the Ninja is 14mm in diameter, but we will make it 1/2 (12.7mm) in diameter to make it lighter. This will reduce the weight by about 20%. Some of them are expensive, such as Brembo's variable-ratio radial masters, but they can be modified reasonably well with stock modifications.
Parts, tools and things needed for this HACK
Replace the clutch master with a CB1300SF Assembly
CB1300SF (SC54)
Part Number: Cylinder Sub-Assy Clutch Master
Part number: 22890-MGY-641
The other thing you'll need is a Daytona conversion connector, as Kawasaki's has a 3 pole clutch switch and Honda's has a 2 pole switch. It's possible to short circuit it, but if you want to do it easily, here's what you need.
Daytona
Product name: Repair Parts for NISSIN Master Cylinder Switch Connector
Part number: 65615
Otherwise, you just need to have a fluid that is crutching the replacement process.
It's not a must, but a syringe (syringe) is useful to release air from the fluid.
How to do the HACK, instructions, work instructions, etc.
After removing the normal clutch fluid, remove the moto's clutch master and install the CB1300SF clutch master.
After installation, fill with fluid and vent the air. It is easy to use a syringe to release the air. I think it's important to use towels and newspapers to protect the paint on the cowl and other parts of the motorcycle from being damaged by spilled fluid.
All that's left to do is replace the switch on the Clutchmaster with a Daytona switch connector and you're good to go.
Summary of HACK
- I'm switching the clutch switch from 3-pole to 2-pole, so if I don't hold the clutch, the engine won't start. (I used to hold the clutch to start the engine out of old habits, so it wasn't a problem.)
- The pull on the clutch lever gets louder. (I had zero discomfort at a level where I could barely feel it.)
Thank you, ninnin, for posting that valuable stock diversion HACK!
