CVO: Street Performer Kit

This performance upgrade is for CVO 110” owners using their existing heads. Both the intake and exhaust ports are CNC ported to provide a very substantial increase in flow and consistency between the heads.

The chamber is left in its natural state so you can utilize your existing flattop pistons and a set of T-Man cams. This kit provides a very cost effective upgrade that will yield a smooth power and torque band throughout the RPM range while maintaining its rideability.

Kit packages require your cylinders and heads be sent to T-Man Performance for work to be completed.
