Originally used on Mk II 848cc engines, this rebuilt 1-1/4" carb can be used for either the left side of a twin carb set-up (radiator side) or on a typical 848cc stock power unit. Completely rebuilt, simply needs jetting to your application. Needles are available separately.Comes with all new seals, gaskets, needle & seat, jet tube assembly and throttle bushings if needed. All parts are inspected, ultrasonically cleaned and polished. The air filter to carb elbow will not be included unless you specify in the comment field you need one. These carbs also now come with the o-ring spindle upgrades as in our WZX1310A kits.
