XS 650 stock CV carbs

XS 650 Stock CV Carbs

Top carb is an early XS 650 36 mm CV carb. It has a raised port floor right at the venturi and flows nearly the same as the bottom 34 mm emissions carb. Second carb has a 36 mm bore all the way through, best stock carb for some performance advantage. Bottom is late model small 34 mm emissions carb with sealed air screww adjustment access. All of these are designed to work with the restrictive stock airbox, stock restrictive exhaust, and really lame for performance applications, even with an aftermarket exhaust system. Mikuni VM & TM round and flat slide carbs are designed to flow more fuel and air at engine design performance ratios, and metering is controlled directly by the rider altering the throttle slide position.
