POLINI reed valve carburetor kit with 24 mm PHBL for Vespa PK XL with 3-hole connection
Complete kit for quick and easy conversion to reed valve intake. The individual parts are perfectly matched to the respective engine type.
The advantage of the diaphragm is that the intake tract can be designed more freely. The intake time is no longer restricted by the rotary valve. This results in significantly more power and torque, especially in the lower and mid-range.
