This pump shoe seal kit comprises of individually moulded plugs that are designed to fill the large cavity air pockets in the OEM pump shoe. By plugging these cavities and re-sealing the shoe with silicone your pump cavity will be 100% free of air pockets and leaks that can cause cavitation. The R&D pump plug kit will increase acceleration and top speed due to creating a more efficient pump inlet system.
Fits Yamaha FZR & FZS (2009-2013).
Note: For use with OEM intake grate.
