@lwsr3, if you are planning to go to tracks with tight sound restrictions you can one of the quiet mufflers that Radical makes. Many people call them “Laguna mufflers”. I have an extra one that I wou...

I just use needlenose pliers to compress the spring from both ends. As you do that you can pull on either one of the ends from under the hook.
