  2. Demon's 114ci Harley-Davidson Evolution-Style Engine Natural and Chrome Finish

    Demon's 114ci Harley-Davidson Evolution-Style Engine Natural and Chrome Finish


    "Demon's 114"
    114ci 4" Bore Polished Engine
    by Ultima






    *Notice: This engine is FACTORY ASSEMBLED. Some of our competitors, especially on eBay, offer engines that are self assembled from spare parts at a lower price. Do not take a risk on a non-factory assembled engine!

    Demon's 114ci 4" bore Engine

    Here at Demon's Cycle we saw a lot of potential in Ultima's 113ci engines. However we thought of a few ways to drastically improve the performance of this engine. We went into partnership with Ultima and after reengenering and implementation of our proposals we are happy to introduce all new 2010 "Demon's 114ci" motor.

    Here are the main differences between Ultima 113ci engine and Demon's 114ci:

    The 113 has 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. We have managed to reduce piston speed in Demon's 114" Motor's.
    This reduction in piston speed results in less wear on the cylinder walls and piston skirts. So its the most reliable engine out there on today's market. This is your future engine and we sell it for the same price as a 113" Ultima engine with special air cleaner , better rocker boxes and thicker head gasket for more reliability and dependability.
    Also, the increase in rod ratio (rod length divided by stroke) lessens the side load on the cylinder walls, reducing friction, heat, and allowing a much more free revving motor.
    By utilizing the MWM 248 cam we were able to retain the great torque characteristics down low and with the increased cylinder fill provided by the increased rod ratio, the Demon's 114 will still pull very hard on the top end.
    Another advantage of the shorter stroke is that the Demon's 114" is smoother than the 113. Being based on the 4 1/4" bore engine family, the Demon's 114" has the much stronger 3 piece crankshaft  used in the 120/127/130/140 series of motors, along with the much stronger rods.
    Billet rocker boxes with holes allow for much better cooling and breathing of the engine.
    Demon's custom billet air intake system allows for much better air flow and unrestricted performance.

    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.

    "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 engineering excellence and competitive pricing brought Demon's 114 to life with a completely new design set of castings 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 and now with our new high flow cylinder heads these engines now can boast the most powerful engines on the market as well!!

    We think that you will agree these engines are the best value anywhere.

    How to Install New Handlebar

    Ever notice how most fine artists depict the devil? They draw this demon
    from hells wings as having sharp angles. This vision was not lost on
    Demons Cycles. Its new 1 1/4"-inch El Diablo handlebars sure remind us of
    devil wings. No matter the imagery, we thought they have a real cool look, as
    did Navy Seaman Mario Guerrero.

    1. The El Diablo handlebars owe their sinister look to their severe angles and gusset plates. They are

    fabricated from 1 1/4-nch tubing and powder coated black.

    2. Our starting point, a 2007 Dyna Street-Bob: the dash, gas tank, and hand controls already have been removed.

    3. The new handlebars have oblong holes to run the control wiring in and out through.

    4.  air nozzle is used to blow the lead  string through the bars,Then a length of
    rope is attached to the string and pulled through
    the bars.

    5. The rope was used to pull the controls wire harnesses through the bars.

    6. The factory risers wer used to mount the new bars.

    7. Because the bars are T inch in diameter at  their center mounting position, a stock
    clamp was used

    8. The control switches were mounted to the bars and their harnesses fined over the top triple tree and routed into the frame.

    9. The switch wiring exits the front of the switch housing and into the bars.

    10. Once the switch houseing were in the place the front brake and clutch levers were attached to the bars

    11. These stunning bars sure remind us of devil wings.
