PE Carburetor

The PE carburettor has a round slide design. It is used in performance-tuned motorbike carburettors. It mixes air and fuel well. It improves throttle response, power, and fuel efficiency. It is popular among racing, dirt bike, and tuned engine enthusiasts.

PWK carburetor is a injection device applied to dirt bike and ATV. The PE carburetor is common in civilian motorcycles. The difference is in the D-slider and round-slider. The PWK carburetor also has a power injection device. It boosts power at high RPMs and improves response.

The easiest way to identify this is to check the carburettor body for the code. A 28mm carburettor will show PWK28.
Or, watch the carburetor sliders. The PWK carburetor sliders are D-shaped and very recognizable.

PE and PWK carburetors are the same in structure. The difference is in the length of the slider and the throttle pipe. PE carburetors use round sliders, while PWK carburetors use D-shaped ones. In large bores, a round slider makes the throttle pipe too long and big. This hurts throttle response. The D-shaped sliders fix this by shortening the pipe and improving response.
