No other carburetor has ever been able to approach the SU in sheer horsepower and economy over a complete RPM range. In the one and only documented comparison test of all aftermarket carburetors for the Harley, the SU easily dominated the others. A closer look at the Eliminator II SU will provide some of the reasons for its wide margin of superiority. To date no other carburetor, to date, is equipped with the sophistication and the features necessary to even approach the Eliminator II SU in performance, dependability and consistency. All Eliminator II SU carburetor kits come with manifold, manifold gasket, all necessary mounting bolts, pushpull throttle brackets and complete installation and tuning instructions. An air cleaner or velocity stack must be ordered separately.
