CLUTCH SPRINGS DO A COUPLE OF THINGS. FIRST, THEY SUPPLY THE PRESSURE TO ENGAGE THE CLUTCH. THEY ALSO DETERMINE THE RATE AT WHICH THE CVT TRANSMISSION CHANGES FROM LOW TO HIGH GEAR ALONG ASSISTING THE COMPRESSION SPRING. A 1000RPM CLUTCH SPRING WILL GO INTO A HIGHER GEAR THAN A 1500RPM CLUTCH SPRING. COLOR COATED IDENTIFY THE STRENGTH OF THE CLUTCH SPRING, FOR EXAMPLE, A CLUTCH SPRING COLOR COATED BLUE IS IDENTIFIED AS 1000 RPM WHICH WILL DELAY THE CLUTCH REACTION BY 1000 RPM. THE GREATER RPM SPRING WILL PROVIDE YOU WITH THE GREATER POWER. NCY COUNTER PRESSURE SPRING 1000 RPM USES A MODIFIED ALLOY SPRING PROVIDING BETTER RESILIENCE AND ABOVE AVERAGE STRENGTH FOR 139QMB, BUDDY50, ROUGHHOUSE, AND MANY ANOTHER GY6 50cc BASE ENGINE
