    Engine Weight 170 Lb Installation Notes: Ultima ® Engines must be installed by a trained professional mechanic into a motorcycle for which its use was intended. Failure to do so may result in injury and even death. It is the customer’s responsibility to insure their mechanic has proper training.

    API service SJ rated motor oils, such as Ultima’s 60 weight oil, MW# 103-111. The oil’s viscosity should be matched with the climate conditions but in most cases Ultima 60 weight motor oil will work fine.

    Compression Release Valves ® All Ultima Shovelhead engines are supplied with manually operated push button compression release valves. These valves aid in starting your engine and can greatly increase your starter and battery life. To operate these simply depress the Top Cap as shown in Figure 1 and they will pop back up automatically once the engine is cranking.

  • Page 10: Exhaust System Selection

    Exhaust System Selection Ultima Shovelhead motors utilize a 3-bolt exhaust mount for added durability, but stock single-bolt exhaust can be used. When selecting exhaust systems avoid large diameter pipes that do not have a smaller primary pipe that exits the head for at least 4-8”. Overall the owner’s satisfaction of the selected pipe is most important but it can also have a negative effect on rated power levels.
  • Page 11: Ignition Systems

    Ultima Shovelhead engines come with an Ultima Fixed Curve Single Fire Ignition System (by Dynatek) with advance Curves and the Rev Limiter preset from the factory and do not require further adjustment. Rev limiter is set at 6,000 RPM. Modifying or tampering with the ignition settings during the engines warranty period will result in your warranty being void.

  • Page 13: Timing Marks

    Timing Marks Ultima ® Shovelhead Engines are supplied with 4 reference timing marks on the flywheel to identify crankshaft location when viewed through the timing hole plug. These marks are as follows: R 2. A Mark 1. = (T:F) Top Dead Center on the Front cylinder—The TDC mark is used for most electronic ignitions as the reference point to begin the static timing process.
  • Page 14 We have found in most cases these Ultima Shovelhead engines will accept full timing before 2500 rpm and this is the best choice for most engines. If you have excessive Spark Knock or detonation go to a slower curve, Colder Spark Plug, Richer Jets or better fuel.
  • Page 15 The instructions show 4 different advance curves for this scenario. Select the curve with the proper total timing shown in this book for your engine. Ultima Ignitions have preset curves and will get you close by static timing the engine at TDC. Dyna 2000 Ignitions will require you to modify the base timing on most engines so the total advance is not too excessive.
  • Page 16 Set the ignition to the OEM with VOES mode but do not install the VOES switch. Instead tape up the wire — Do NOT Ground this wire on the HI4 System or Ultima ignition system. Put the ignition in Kick Start Mode as they will fire on the first revolution and typically start much easier this way.
  • Page 17 Spark plugs Recommendations: There are a variety of spark plug manufacturers who make the proper style and heat range plugs for the Ultima Shovelhead engines. Engines that have excessive spark knock may require a colder heat range and or richer air/fuel mixtures and retard the timing. We also recommend using the coldest plug your combination/environment and fuel will allow for best overall engine life and performance.

  • Page 20: Initial Start-Up

    Initial Start Up One of the most important parts of the break-in procedure is the initial starting of your engine!!!! Read this completely before starting the engine!!!!!! 1. Remove the Air Filter Cover. 2. Twist the throttle wide open and make sure that the accelerator pump is working. 3.
  • Page 21 Break-in procedures for Ultima® Engines Follow these guidelines closely or you may void your warranty. Avoid over heating your engine!!!!!!!!!!! The heat of a new engine can be directly related to engine rpm, load and friction. Do not lug the engine. If you have a 6-speed transmission do not run your bike in 6th gear during break-in. We strongly recommend you keep the engine rpm above 2400 and below 3500 rpm for the first 500 miles and run the engine at varying speeds.

    “Wear-In” period, engines produce very small metallic pieces that need a good filter to remove them. We do not recommend extremely fine 10-micron filters during this time as they can clog quickly and begin to by-pass oil instead of filtering it. Use the 40 Micron Filters during break-in and for the life of the engine. Ultima ®...
