38mm Mikuni Wax racing blenders

Small changes can make a big difference.
Inside every carburetor are small bumps, casting flaws, and edges that disturb airflow.
Even though they seem tiny, these imperfections hurt performance — especially in high-RPM racing engines.

We found a way to fix that.

By designing a smarter flame arrestor adapter that smooths the airflow inside the carburetor, we recovered almost 10% more usable airflow.
The result?
Our 38mm carburetor now flows like a 40mm carb — without changing the carb itself and without breaking Lites class rules.
