My front tire just kicks up all sorts of grime and oil and wetness onto my tank and onto the back of the forks, and onto the top of the fender. The fender doesn't seem to be doing it's job so well. Has anyone else noticed this? I dunno if it's the fender's fault, if it's because this is my first motorcycle in 20 years that doesn't have a radiator to catch all that stuff, or what. But my bike is constantly filthy!
