I agree with you on lowering the shifter a bit. However, that does not fix the issue. The bushings in the shifter are nylon and improperly sized. I have owned 33 bikes of all different makes. I have never seen a shifter as sloppy as this. These types of things lead to failure and need to be addressed. I definitely agree with you as to not trusting other peoples work. I basically go over the bike every 300 miles to make sure things are tight and working correctly. I this case the bolt was still tight. I had to loosen it with a wrench to put it back on and it was pretty tight. This is why I feel there is a larger problem with the shifter.
