Looking for high performance engine specifications for your Harley- Davidson motorcycle? Need to know what high performance equipment provides the best performance at the lowest costs for your H-D. Here you can look at performance modifications with the dyno runs of many different engine combinations, so you can pick your own equipment, horsepower rating and dollars to spend. An incremental approach to engine development has provided some good results on many engines. Find out what combination of carburetor, camshaft, exhaust systems, ignition systems, head work, pistons and the other high performance components work well. There are tests of some equipment that did not work well. Know what works and what does not. Compare the results of your current bike to those seen here. Are you getting the performance you paid for? If you have had success in your engine development program, send a picture of the bike and your performance results (dyno sheets or time slips) to the V -Twin Café for publication. The V -Twin Café is always looking for good articles on motorcycle performance work. If you write performance oriented articles, contact us. Twin Cam 88 and 95 cubic inches Twin Cam Engines from Harley-Davidson have a good design and some nice upgrades available from the local Dealer including a 95 cubic inch big bore kit. What can you expect from this engine? Here are some engine configurations that have been tested. 45 to 50 HP Stock Evolution Engines are the starting point for all the modifications. The only way to validate what the performance gain was for any change is to have dyno runs before and after. These are the before runs of several bikes. 55 to 65 HP Up to $750 Stage One Evolution Harley-Davidson engines involve no internal changes made to the engine. All modifications are made by changing or modifications to external components on the engine. These components include air cleaners, carburetors, exhaust systems and ignition systems. No special tools or training is required to perform stage one modifications.

REMOVAL Prepare for Service 1. Position motorcycle on a suitable lift. NOTE If vehicle is equipped with Harley-Davidson Smart Security System, see owner’s manual for instructions to disarm the system. To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect negative (-) battery cable before proceeding. (00048a) 2. Disconnect battery cables, negative (-) battery cable first. 3. Remove seat according to the instructions in the service manual. 4. Refer to service manual to remove left saddlebag and side cover. When servicing the fuel system, do not smoke or allow open flame or sparks in the vicinity. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00330a) 5. Remove fuel tank according to the instructions in the service manual. Remove Engine Components 1. Remove existing air cleaner assembly. Discard backplate but save remaining parts. Refer to AIR CLEANER REMOVAL in service manual. 2. Remove existing exhaust system. Refer to EXHAUST SYSTEM REMOVAL in service manual. 3. Remove engine from chassis following the instructions in the service manual. 4. Disassemble engine top end and bottom end. Refer to appropriate ENGINE sections in service manual. 5. Remove existing clutch diaphragm spring. Refer to CLUTCH REMOVAL in service manual. The procedures in this instruction sheet should be performed by one experienced in precision measuring techniques. Failure to meet tolerances called for in this instruction sheet can result in engine damage. (00511b) -J04793 1 2 is03517 1. O-ring counterbore 2. Spigot bore Figure 1.

Cylinder Wall MACHINE CRANKCASE Crankcase Boring Preparation NOTE During final assembly of the engine, Harley-Davidson recommends replacing the OE cylinder studs with Screamin’ Eagle High Tensile Studs (16505-01). 1. Remove cylinder studs from the engine crankcase. 2. Mask off all bearings and oil holes to prevent debris and contaminants from entering those areas. 3. Inspect and clean engine case mating surfaces. 4. See Figure 6. Reassemble engine case with OE screws, except the top center screw between the cylinders, and tighten to specifications listed in service manual. NOTE To prevent damage to crankcase boring tool, it is important to replace the top center screw with a modified top center screw (1093). This screw is included in the Crankcase Boring Tool Kit (94419-06) and can be purchased separately from a Harley- Davidson dealer. 5. Install modified top center screw (1093) between the cylinders and tighten to 50-90 in-lbs (5.6-10.2 Nm). 6. See Figure 1 and Table 1. Machine crankcase cylinder spigot bore and O-ring counterbore to the dimensions shown. Modify Crankcase

Harley-Davidson Electronic Sequential Port Fuel Injection System, (ESPFI) This completely new engine management system was released starting with select 2001 model year Softail motorcycles. This system is a speed/density, open loop, sequential port fuel injection design that also controls spark timing and spark intensity. Speed/Density System – When the ECM monitors manifold air pressure, air temperature, throttle position and engine rpm to manage fuel delivery. Open Loop Control – When the ECM monitors sensors positioned on the intake side of the engine and does not monitor the end result of internal combustion at the exhaust. Sequential Port Fuel Injection – When the injector nozzle is positioned in the manifold near the intake valve and is precisely timed to deliver fuel to each cylinder. This ESPFI system is the exclusive design used on 2001 and Later EFI-equipped Softail models, 2002 and Later EFI-equipped Touring models, 2004 and Later Dyna models, and 2004 and later V-Rod models. Current ESPFI Components The following is a list of the major components of Harley-Davidson’s current ESPFI system. It is important to have an understanding of what these components do before learning how the ESPFI system functions. Refer to the appropriate Harley-Davidson Service Manual for the vehicle you are working on for additional information on component design and function and for the physical location and testing procedures for each individual component. ECM – Electronic Control Module – this is the brain of the system that collects input signals from multiple sensors, makes decisions and sends output signals to deliver fuel and spark to the engine. CKP – Crank Position Sensor – this sensor provides input signals to the ECM that indicate engine rpm, (how fast the engine is running in R evolutions P er M inute). The ECM also uses these inputs to determine what stroke the engine is in so it can deliver the fuel and spark at the desired time.

Progressive Suspension shocks for your Softail are designed as a direct bolt on replacement for your stockers. Although they are very similar in appearance, they have vastly improved damping and spring rates. Our shocks do not use the remote reservoir system used on earlier model Softail models. 1. Place motorcycle securely on stand or blocks so the rear wheel is slightly off the ground. 2. Per instructions in a authorized shop manual, remove your old shocks. Note location of the mounting hardware. 3. Install the Progressive Suspension shocks using the stock mounting bolts and washers. 4. Tighten all shock mounting bolts to the proper torque specifications (see shop manual for specs) 5. Progressive Suspension shocks have adjustable pre-load to compensate for varying weights. The included wrench or a Harley Davidson pre-load adjustment wrench is necessary to adjust the pre-load setting. Replacement Progressive Suspension, Inc. wrenches are available as Part # SW-784 from most Dealers and Accessory Stores and the Harley Davidson wrench is available as part #94455-89 from any Harley Davidson Dealer. Spring preload is set by us to the lightest setting. To increase preload for heavier riders/loads/passengers, loosen locknut with the inside portion of the supplied wrench or a 1 1/ 16 ” wrench and back it off several turns. Use the supplied wrench or a Harley adjustment wrench to turn the adjustment nut counterclockwise to the desired preload setting. Then tighten the 11/ 16 ” lock nut. Both shocks must be adjusted to the same, equal setting
