Powerblade for Keihin PWK38 carburetors.
This works! The powerblade slices the carburetor venturi into 2 smaller venturi's, increasing the air speed in both. This results in better throttle response and increased low-end power. This is a plug-and-play device, no modifications re re-jetting required.
This fits: the short-body Keihin PWK38 carburetor.
Complete as pictured.
