I just bought a 2000 zx7r with 6000 miles on it. This is my first bike i ever had and i have no clue about it. i just have two questions for now. I want to clean the air filter, can i use the K&N cleaner and oil kit i use for my car? Cause the filter is a piece of foam, so i wasnt sure if it made a difference. Second, i want to replace the fuel filter. I dont know the size of it or the fuel lines. Do i have to order one from a dealer or is it something i can buy from a auto parts store.
