just got another bike!!! Ive heard alot about oiling issues...the guy I got the bike from said that kawasaki resolved the oiling issues and the 97 is okay.is this true??? what other issues does anyone know of...I should know?? I had a 1980 1000 the engine had alot of engine noise.not rattles or knocks...but valves and such,shifts were well noted...the zx11 has the same engine noises.are these common??? the bikes got 13k on it..what should I do besides oil and filter change to keep the bike in shape????
