S6-31RT-PWK21 Carburetor PWK Stage6 R/T

Stage6 R/T carburetor type PWK 21 - 34 mm

The Stage6 R/T PWK flat slide carburetor from KOSO is produced especially for Stage6. The racing carburetor is designed for high performance 50cc - 70cc racing and high-end racing setups.

Carburetor design Stage6 R/T

The polished, turned out intake provides better airflow for improved engine response. The outer dimensions of the carburetor as well as the intake manifold connection  (35mm or 39mm for the 30-, 32- and 34mm versions) have been reduced for easier installation. In addition, the black racing finish makes the carburetor look particularly classy. And of course, this PWK carburetor is also equipped with a Powerjet.

For even better pull, we recommend combining it with a double layer air filter from Stage6 or even using an intake bellmouth.

Note 1: Carburetor has no oil port. Conversion to using premix is necessary!

Note 2: The installation of this carburetor type requires changing the intake manifold as well as the original throttle cable.
