Zipper’s Twin Cam® CVO Muscle 110 Kit

Does your CVO 110 seem to run flat after 4,500 RPM?
It’s true – the factory 110 engine is better at producing torque than HP. Zipper’s Muscle 110 kit starts producing more torque at 2,500, then just when the factory engine starts leveling out at 4,250, the Muscle 110 takes a deep breath and charges hard to 6,200 RPM – making an astonishing 40 HP more! Peak torque occurs at 5,100 RPM, 34 ft/lbs more that stock, contributing to the hard pull on felt in your arms. How do we do it? Zipper’s Stage III CVO CNC porting, proprietary +10cc pistons and Red Shift 657 cams provide everything needed to produce the power. Valve springs and Red Shift Dual-Piston tensioners with Pro-Taper pushrods add stability and life to the unstable factory valve train.
Whether you ride in short hops or long trips, you’ll fall in love with your CVO again with the Muscle 110!

CVO engines are known for lifter and oil system issues, so our blueprinted cam chest upgrade is highly recommended.

This kit uses your factory head and cylinder cores sent in for modification.
