First and Foremost I would like to say I'm new to the forum and hello. I recently acquired a 2001 Kawasaki Ninja zx6r. It was laid down from the idiot previous owner. It is all fixed up and runs fine. The last thing i need to do is add brake fluid to the rear brake (which I replaced). This is where Im confused. I cannot tell what kind of brake fluid is, or should be, used on the bike. On the fronts, the color of the brake fluid is a very very slight clear-pinkish color. Could this be a DOT 5, or is it more purple? On the resivoir cap it calls for DOT 4 fluid but doesnt that stuff is usually looks like new motor oil? Im not too savvy on brake fluids. Are there general rules to brake fluid on bikes, or is sound like DOT 4 is going to be okay for my zx6r? Id love to show you pics of my bike, but the only ones I have are the accident pictures on a tow truck and leaking motor oil from the cracked stator cover, etc...
