Hello and welcome
Rimm
Thank you.
I was born and live in the north of Russia.
Unfortunately, there is practically no information on the Russian-language Internet resources dedicated to the Kawasaki Z, KZ, GPZ series. I am very glad that I found kzrider.com.
I beg your pardon, my knowledge of the English language is scarce.
To install the Yamaha XJR400 fuel tank, you will need to weld 2 pieces of 25mm pipe to the frame.
The original tank attachment protrusions do not need to be removed.
Rubber damper 35-38 мм.
Weld the stud. Which makes it possible to fix the fuel tank in the hole near the seat.
Unfortunately, I have no idea how the XJR fuel tank will pair with the original KAWASAKI seat.
With respect, Roman.
