This kit was developed for the rider looking for a solid “seat of the pants” increase you can feel – every time you roll on the throttle. The increase in displacement and the bump in compression deliver a significant increase in torque and power over stock while restoring the sensation of riding solo when taking that long trip with a passenger and luggage.

  • Increases power by up to 24% when compared to the Original Equipment engine configuration
  • Delivers increased throttle response throughout the entire RPM range
  • Produces flexible roll-on passing power without a required downshift
  • Delivers excellent stop-light to freeway speed on-ramp acceleration
  • Retains Original Equipment Factory Warranty
  • 50-State U.S. EPA compliant
  • Includes 4.075" Bolt-On Cylinders, Forged 11:1 High Compression Aluminum Coated Pistons, High Performance Piston Rings and Tappets, SE8-498 Cam, Performance Valve Springs
  • Includes Multi-Layer Coated Head Gaskets, Cam Bearing Upgrade, High Capacity Clutch Springs (1200N), most necessary gaskets and seals

Milwaukee-Eight Engine Stage III Kit-114CI to 117CI is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Oil sumping Had dealer install this stage 3 kit on my 2017 CVO Street Glide along with a set of Street Cannons. Well, after approximately 2800 miles, the bike started getting hot and losing power. Turns out the bike was sumping. A lot of money (parts and labor) for a headache.

In the description it shows the same jug and piston size as 107 to 114 size how can that be a 114 to 117 with the same bore as 114?

Asked by: HeavyMetalChazz
Hey HeavyMetalChazz, Thanks for your question. The 107 and 114 Original Equipment engines use different strokes. Thus, if you use a 4.075” cylinder bore on 2 different strokes; the resulting displacements are different. Hope that helps!

Can I use a different cam, i.e. torque cam, for earlier rpm torque with this kit?

I like the increased displacement but would like the torque curve to start earlier than the SE8-498 cam.
Asked by: Curt1948

I installed this kit on my 2017 cvo and I'm wondering when you will come out with bigger heads and a throttle body. Any idea if this is in the works ?

Do the intake assembly and tuner have to be upgraded also when installing this kit?
