The unique flexi-rigid adapter easily allows synchronization of machines with difficult-to-reach 5mm or 6mm carburetor or fuel-injection vacuum ports; simply bend the outer sheath to the appropriate angle/shape and then turn the inner tube to thread the brass fitting into the vacuum port
The extended vacuum adapter includes 1.5ft of santoprene hose and is ideal for permanent mounting on sportbikes or any other vehicles where access to the carburetor or fuel-injection synchronizing ports requires removal of various side panels, air filters or the fuel tank
