I would like to run only 1 CRG mirror, and mount it on the left side by removing the bar end weight and use the adapter that goes into the handlebar tube. Would it be o.k. to ditch one bar end weight, and leave the other side on? If so, how do I get the bar end weight off? I tried to break the allen bolt loose on the end of the weight with no luck. Does it loosen by turning the common counter clockwise? Thanks for the help.
