Yo-yo Modifications, or Mods, are changes made to a stock yo-yo by Modders, aiming to make them function better or be more aesthetically pleasing. Often these mods find their way into newer stock yo-yos. (eg. many manufacturers these days recess the response systems on their yo-yos).
The following is a list of commonly made modifications.
- Recessing - Keeping the friction stickers away from the string
- Shaved O-Ring Mod - Making the O-ring flush with the walls (equivalent to recessed friction stickers)
- Siliconing - Filling the O-ring gap or recess with silicone
- Sanding - Reducing surface friction for better grinds
- Adding Shims - Widening the string gap
- Changing the bearing - For example putting in a Dif-e-Yo KonKave bearing.
- Adding Side Cap Bearings - Allows the user to perform matador style tricks.
- Schmoove Rings - Adding extra grooves to the inside of the yo-yo in order to reduce string friction against the side walls.
- High Wall - Removing material from the face of the yo-yo to improve freehand performance.
People who invent or modify Yo-yos, commonly known as Modders. In the yo-yo community modders are often called upon to take a yo-yo to the next level of playability. Many of the now common advancements in yo-yo technology were first attempted and developed by modders.
