Description

A properly sized main jet is critical for carb tuning—it directly controls fuel delivery at mid-to-high throttle openings, affecting power output, throttle response, and engine longevity. The #150 jet is a common baseline or step-up size for Mikuni VM-series carburetors on modified or performance engines. This 4-pack gives you the flexibility to dial in your air-fuel ratio without repeated single-jet purchases.

Whether you're tuning for altitude changes, engine modifications, or simply replacing worn jets, having multiple #150 jets on hand ensures you can optimize performance across different riding conditions and carburetor setups.

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!
