Depending on how many coats of clear you put on the tank, you could color sand the clear to mirror flatness.
But you need to have enough thickness in the clear.
It pretty easy just be patient with the process.
I've posted this before, but I'll post it again as it shows the process done by hand.
If you know the process, you can make a $100 paint job look much more expensive.
It's just very labor intensive.
New New Update: I never did find a solution to this long term. Every filler and patch that I tried, ended up peeling off (yes, even after following the instructions exactly.)
The gas tank holes are just too big, I think. They are not really pin holes.
I've sanded this down and replaced the patch 4 times now. Enough.
It seems Yamaha xjr400 tank is a good fit. Looks pretty rad too. I will start looking for one. Thank you!
I have some friends who helped me with the translation:
Спасибо большое!!! Пришлось ли вам делать какие-то регулировки чтобы укрепить бак к раме? Я начну искать прямо сейчас! Украина выглядит забавным местом для катания!
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.
