Top Kit can be used after chrome grip flange is removed. Bottom Kit may interfere with use of indicator button on housing.Friction Pads are required.The 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.Which friction pad should you use?The friction pads come in 3 different thicknesses. Your kit comes with ONE of each size but you will only need to apply one pad to your Throttle Lock. You will want to start with the thickest friction pad and see if it fits between the throttle housing and the Throttle Lock Stopper Arm. If it doesn't fit, try the next size down until you find the right size that does not make contact with the throttle housing when disengaged.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.ProductMaterial Type: Durable Stainless SteelColour: BlackProduct Type:Bottom Kit or Top KitNote:If you have any questions when purchasing this product, please contact me.
