I would like to thank every-one for their greatly appreciated input. I am absolutely anal about washing my bike. It is almost to a disorder level. I ride with guys that have never washed a motorcycle in their lives. ( cuts into their riding time ) and that’s O.K. I don’t judge. However the radiator/grill area just escaped me. Had it not been for the temp guage I never would have went looking in that area. I think once I get my present situation sorted I am just going to make sure I pay attention to that spot also and that should clear the issue.
