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.

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