This FLAT SLIDE SMOOTHBORE design cuts down the turbulence in the bore-throat to increase air flow efficiency. Smoothbore design eliminates various orifices and obstacles in the carb throat which cuts down the turbulence to increase air flow efficiency.
Flat slide design helps create a smooth bore effect, increasing air flow. Significant performance improvements over older round slide carbs. Great throttle response because of more precise fuel metering. All are center-pull style throttle, unless noted by footnote. Jetting may need to be changed per application.
Dimension A= 47mm, B= 100mm, C= 170mm, D= 62mm, Total Width 75mm. 1.50", 38 MM, 38,00 MM (1,50"), 38.00 MM. The carb/carbs are afternarket and tuned close so they can be ran as-is, if you have a non stock machine please let me know the modifications so we can assist you with jetting.
