Just put mine on today. Do the throttle side first. When putting on the left side, put a piece of masking tape on directional housing and your new grip on a dry run. This way you can line up the left grip with the right. Then cut the piece of tape leaving a piece on the housing and your new grip. Put the glue on the handlebar and then slide the grip on lining up the tape edges. Works perfect, then both left and right side are matched.
