I have a Springer too & have only had this issue when I changed grips to VZ composite grips.
I have never had this issue with wood grips (which are somewhat softer than the composites and will allow you to tighten them down a bit tighter and the softer wood seems to cushion/absorb vibration better).
However, to solve this problem, I simply went up to Lowes or Home Depot and bought a very inexpensive set of the smallest rubber O-rings. I forget the size. I can look when I get at home. This will completely solve the problem (unless you just want to buy new grip screws - but you will likely have the same issue with new screws as well unless you get the O-rings).
