Today let’s talk about...the crankcase pressure relief check valve! 

#Active one-way valve#Gravity one-way valve#Passive one-way valve
In the section about cleaning the oil and gas separation chamber of the motorcycle air filter box, I talked about the process and importance of generating and releasing pressure in the crankcase of a motorcycle. Maybe many friends want to buy one because the original motorcycle is not equipped with a one-way valve. To install, but there are so many types of one-way valves on the market, whether they are xenografts (current use) or modified products specially designed for motorcycles, it is a headache. So today we will talk about the selection and installation of one-way valves. Something to note!
