Upgraded Accelerator Pump Rebuild Kit for Yamaha and Race-Ready Performance

Restore precise fuel delivery and reliable pump action with the All Balls Racing Accelerator Pump Rebuild Kit 46-3005. Built for closed-course racing, this kit is engineered to help your dirt bike maintain consistent throttle response under demanding riding conditions. While it isn’t a guarantee of race results, it offers components designed to improve durability and operational feel during maintenance and rebuilds.

What’s included and how it helps

  • All components required to properly rebuild the accelerator pump assembly, facilitating a complete refresh in one kit.
  • POM composite washer bearings replace thrust needle washers, delivering increased service life and improved resistance to water and dirt.
  • All metal bushings are case hardened and plated to prevent wear and corrosion in challenging riding environments.
  • Needle bearing shafts use SCM415/42 bearing steel that is hardened and precision ground for consistently smooth operation.

Durability, precision, and real-world use

  • Hard-wearing materials help resist wear in tough riding conditions, supporting longer intervals between maintenance.
  • Precise manufacturing aims to ensure a reliable fit, stable spray, and smoother pumping action when the throttle is opened hard.
  • Designed for closed-course racing scenarios, this kit is best suited for bikes used in track or competition settings.
  • Component hardening and plating provide corrosion resistance, helping the kit maintain performance after rides through dust, water, and debris.

Compatibility and application notes

The kit is intended for Yamaha models including WR450F (2003–2011), YFZ450 (2004–2009), and YZ450F (2003–2009). It also references broader applications listed for other brands and models, so verify fit with your specific bike before purchasing to ensure correct compatibility. This kit is labeled for closed-course racing use and should be installed by riders familiar with accelerator pump maintenance.
