Description

If you're running a Holley 4150 carb and want to unlock higher airflow capacity, this retrofit kit eliminates the need for a complete carburetor swap.

By upgrading to an HP-spec main body, you'll improve throttle response and fuel delivery consistency across your engine's RPM range.

  • HP main body
  • 4150 retrofit design
  • Aluminum construction
  • Chromate finish
  • Bolt-on installation
  • Holley compatible

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
