Polini CP 23 Carburetor Conversion Kit compatible with your Vespa VM, VN, VB1, VL, VD, and Acma GL.
Developed by Polini, this racing carburetor features a compact design and is approximately 40% lighter than comparable carburetors. The short intake path and circular passage optimize airflow. The larger needle valve and a modified mixing tube enhance the atomization of the fuel-air mixture. This makes it easier to tune the carburetor. Additionally, fuel consumption is reduced even at high power output.
It is mounted to the intake manifold using a rubber sleeve.
The following components for installation and tuning are included in the package:
1x intake rubber
2x hose clamps
1x secondary jet in size 38
1x idle correction jet in size 60 (0.6)
1x main jets in sizes 92, 95, 98, 100, 102, 108, 112, 115
1x swiing® revival jet box for safe storage of the valuable jets
1x Bollag Motos throttle cable rocker V2 (includes all mounting hardware)
You can find individual racing carburetors and other performance-enhancing products in the accessories section.
