Hey I know this is going to sound really stupid, but my right mirror won't stay tight in the position that I want it. I can continue to screw it in until it's tight but then it's facing the other way...I ride down the street and all I can see is my right arm. I'm I just an idiot or what? I have tried taking it off and then repositioning it so it will end up in the place I want...but that doesn't work it's brand new and pissing me off. what can I do?
