48MM CARB, POLISHED FINISH

The new HSR48 was developed for large, highly tuned engines. It flows 26% more air than the HSR42 and 14% more than the HSR45. Highly developed engines with large valves and expert port modifications can gain peak power using the HSR48. Engines with stock ports do not benefit from the 48's greater flow. - These high-performance carbs are ideal for realizing the maximum potential from custom and race engines - Available in standard or highly-polished finishes - Both use stock H-D cables and come with a flange - For race and custom applications only
