Description

Phenolic carburetor spacers are essential for serious carbureted builds—they provide thermal insulation that keeps fuel cooler and reduces vapor lock while maintaining consistent jetting performance under sustained load. The Moroso 1-inch open design fits square-bore applications and installs as a direct bolt-on, making it an efficient upgrade for street and racing engines alike. This is the kind of foundational component that separates dialed-in builds from ones that leave power on the table.

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!
