What is the AIR CUT-OFF VALVE on the carburetor for (i.a. VTX 1300)? A vaccum hose is connected to its output. How does it work? In my case, when the vaccum hose was disconnected, the exhaust pipes were poping (afterfire) during the deceleration.
Excellent expalanation ..could you provide such book summary with drawing so more step bynstep when we start to try implement this theory on carb directly...🙏🙏🤲 thanks
