Carburetor vent cap

Vent cap for the Keihin CVK carburetors used by Ural. If your carb's float chamber vent doesn't have this on it, you risk water getting into the float bowl.

You can also connect a hose to the vent and run the open end of the hose upwards, to somewhere that's protected from rain and splashes.

Or if you have access to a 3D printer, you can make one for less than the price of a single peanut, using the model designed and shared by user SH LEE (from South Korea) on SovietSteeds.com.
