For Yamaha V Star 1300 All Years XVS1300A Midnight Star Motorcycle Cruise Control Handlebar Throttle Lock Assist

Friction Pads are required.

The GFYSHIP Throttle Lock was designed to be used with friction pads. Friction pads can last anywhere from 3,000 miles to 40,000+ miles. The wear depends on how often you rotate the throttle while it is engaged and if your throttle housings has sharp edges that rub on the friction pad. 

Where should I place my friction pad?

We recommend adhering the friction pad along the top edge of the Stopper Arm, but, for some motorcycles, this isn't the best solution. If your throttle housing has any bevels on it which will interfere with the friction pad during any part of the rotation, then you will want to adjust the placement of the friction pad to avoid those bevels. Sometimes this means placing the friction pad a few millimeters away from the top edge of the stopper arm, or maybe placing it to the far right or left on the stopper arm.
