Hi, another newbie question. Recently met another fella who had same bike as mine. Only his sounded... clean. i wanted to change the spark plugs before getting the carby cleaned. does anyone know how to get there? It looks as though its behind the radiator... or do I need to pull out the chamber for the air filter? I have a ZX2R 89 / ZXR250a twin headlights.. THANK YOU ps.. where should i get new spark plugs from?
