Not sure about the zx4r, but the zx6r definitely doesn't require that to change spark plugs lol
it’s not a problem at all. Similar to most sportbikes with the airbox over the valve cover.Obviously I’m way ahead of myself here. But, a friend told me that to change the ZX-6R plugs, one has to lower the engine, is this even true?
How challenging is it to change the plugs on our ZX-4RR’s? Thanks in advance.
