Demon Cycle Black and Chrome 114ci Evolution-Style Engine for Harley Davidson Facts

We saw a lot of potential in Ultima's 113ci engines, and saw opportunity to drastically improve the performance of this engine. So we went in to partnership with Ultima and after some re-engineering and implementation of our proposals we are happy to introduce our all new Demon's 114ci motor.

Our Improvements

Piston Speed

We have managed to reduce piston speed in Demon's 114 Motor's. The 113 had a 4 1/2 in stroke and a 4" bore. The 113 is an under square motor (more stroke than bore) and has much higher piston speed (linear feet per second) than the Demon's 114" - which has a 4" stroke and 4 1/4 bore.

This reduction in piston speed results in less wear on the cylinder walls and piston skirts making it the most reliable engine out there on today's market. 

Another advantage of the shorter stroke is that the Demon's 114 is much smoother than the 113. Being based in the 4 1/4" bore engine family, the Demon's 114 has a much stronger 3 piece crankshaft used in the 120/127/130/140 series of motors, along with the much stronger rods.

Rod Ratio

We also increased the rod ratio (rod length divided by stroke), which lessens the side load on the cylinder walls - reducing friction, heat, and allowing a much more free revving motor.

Cam

By utilizing a MWM 248 cam, we were able to retain the great torque characteristics down low. With the increased cylinder fill provided by the increased rod ratio - the Demon's 114 will still pull very hard on the top end.

Rocker Boxes

Billet rocker boxes with holes allow for much better cooling and breathing of the engine. emon's 114 custom billet air intake system allows for much better air flow and unrestricted performance.

Size

We should mention that the Demon's 114 is .125 shorter than a 120/127 for those early Softail frames that are a bitch to fit a 120/127 in. And, a lot more exhaust systems will fit with less hassle than on a 120/127.

Carburetor
Ultima is proud to introduce our performance carburetors, directly interchangeable with S&S Super G Carburetors. Ultima carburetors will accept S&S jets and S&S bolt pattern air filter assemblies.

Design

Patented design improvements - a relocated accelerator pump nozzle for increased throttle response and THUNDER JETS are a bolt on! Simply remove the plugs and screw in the Thunder Jet. No expensive machining required!

"Demon's" series engines which are designed to provide our customers with a USA built High Performance engine that was priced to be the best value of any engines now on the market. Ultima's commitment to engineering excellence and competitive pricing brought Demon's 114 to life with a completely new design emphasizing performance, reliability, and value.

All of the castings in these Engines are poured in US foundries and are based on all new CAD designs cast from C355 Aluminum a common US Military alloy known for its stability over multiple heat cycles. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability. All of our engines are dynamically balanced using proprietary methods to provide the smoothest running engines on the market. With our new high flow cylinder heads these engines now can boast the most powerful engines on the market as well!
