Maximum horsepower is typically increased from 58-60 to 72-75 HP, and Max torque from 71-73 to 81-85 ft/lbs.

Note: This example “before and after” power increase was produced with the combination of the Mikuni HSR42, a Screamin’ Eagle Air Filter and a set of (loud) Screamin’ Eagle mufflers.”

This Performance Carburetor Kit works with stock manifold and throttle cables, choke cable and air cleaner. This Kit includes carb adaptor and replaces stock CV carb for more power and dependability.
