Works great on a 15mm carb set up. We use this with the rubber mount device for Bing and it works great. Use with: https://www.treatland.tv/bing-air-filter-rubber-p/puch-bing-filter-rubber.htm

wont work without velocity stack

Like any uni filter its well made, but it needs some sort of velocity stack to work with a puch bing. The end is thicker and more restrictive than the sides. If you just attach this straight to the carb the air comes in from the sides, makes flow thru the carb turbulent. The carb cant work right with turbulent air. Maybe this will be useful if you attach it to the tube from the high flow intakes, but on its own it's not the answer. Need laminar flow.
