Out riding on Sunday and i ran out of fuel after thinking i would get more miles then i did but never mind. Anyway, i think since i ran out i must have sucked up all the crap at the bottom of the tank and now when giving it some it feels like the power band is kicking in later at about 6,000rpm when usually i feel it about 4 and then 8ish. I am thinking of changing the fuel filter but was wondering if there is something that maybe i could flush the engine with to help it a bit more. Also does anyone know of a good website that can show me how to change the fuel filter on my bike? My bike is a 1998 Kawasaki Ninja ZX6R Any help will be great
