These Dual Carb Slide Breather vents provide a solution to keeping your Dual Carb-fed best, and clean. If you have a dual carb shadow you've probably seen those two black nipples on the outside of each carb, these are the slide breather vents.
Unfortunately, when these are left open they can draw some dust in. These slide chamber breather vents will keep your slide chamber clean and breathing freely for top performance no matter where your journey takes you!
Insert one stainless mesh disc in the breather, then the foam then another stainless mesh disc and then push the snap ring into place inside the breather.
