Be sure to cut/remove the nubs at the end of the throttle barrel. Make sure that you do have the right hand grip for the throttle side. I didn't have to glue mine cause it was extremely hard to go on. Had to use water and a mild soap to lubricate it before it went on,, with major workbench force. JUST BE SURE TO REMOVE THE THROTTLE BARREL FROM THE BIKE!!! If you force it on while turn it back and forth you will damage the area where the throttle cables connnect which is weak already. can sheer off the tabs that ancher the cables. I learned the hard way. First set of grips went on fairly easy with twisting force and the glue in place. 1 mile from the house the throttle barrel let go where the cables connect,,,,,,, another set of grips and a throttle barrel later I got to ride again. $100 screw-up.
