PAIR Valve Systems Explained

Brock Davidson talks PAIR valve systems. What is it? What does it do and what does it mean to you and your motorcycle? We are addressing it with our 2017 GSX-R1000 project, so Brock decided to stop and allow you to explore this sometimes ‘mysterious’ system with him as he works his way from ‘Stock to Brock’!
