The Magneti-Marelli system used on EVO and Twin Cam FLH’s until 2001 and Buell XL engines is an Alpha-N EFI system. On these bikes, load sensing is determined by the throttle position. The newer Delphi EFI system used on current Twin Cam engines is a Speed Density system.
What can I do about my Harley Davidson twin cam engine?
Harley Cooling is an effective way to help your twin cam engine. The oil cooler features a controlled fan that provides a continuous flow of cooling air, thus helping your engines cool down and reduce the wearing of the plastic shoes.

The total displacement of the 88 twin cam engine is 1450 cc, or 88
What kind of EFI system does a twin cam engine use?
The newer Delphi EFI system used on current Twin Cam engines is a Speed Density system. Speed Density EFI systems determine the engine load based on the intake manifold vacuum.
What kind of fuel injection does a Harley Davidson have?
In theory Harley’s fuel injection system is still an open-loop system by design. Article courtesy of American Iron Magazine The Harley-Davidson ESPFI system is known as a Speed/Density, Open Loop, Sequential Port Fuel Injection system, that controls both fuel flow, and spark timing. Let’s further explain these terms.
When to use open loop fuel injection on Harley Davidson?
Since Harley only uses narrow band sensors (NBO2) capable of only a very narrow range of Air/fuel ratio (AFR), the ECM can only control the mixture under cruising or very low load conditions. Under all other conditions the ECM switches to Open Loop as described in this article.
What kind of motor does a Harley Davidson Twin Cam have?
Combine an even bigger 4″ bore with the longer 4.375″ stroke, and CVO had a new Twin Cam 110 motor in their Dyna, Softail, Electra Glide, and Road King Customs. There were not any major upgrades or updates to the Harley lineup this year, but there was major work from the styling department in two new, wild, Softail models.
What kind of mufflers does Rinehart racing use?
Outgun the competition with Rinehart Racing slip-on mufflers, full exhaust systems, and air intake. Don’t pay for labor, tuning, or additional parts. Get the iconic Rinehart sound with just 2 bolts and 1 clamp – it’s that easy!
How does correct compression work on a Harley Davidson?
Corrected compression takes into account the point at which the intake valve closes after BDC on the compression stroke. The later the valve closes, the lower the corrected compression ratio. For an optimized engine, the corrected compression ratio should be matched to the vehicle’s application and fuel octane.
What makes a Harley Davidson engine so special?
The knowledge of what makes an engine truly move a rider runs deep at The Motor Company, and it was put to good use when we created the Twin Cam 103 engine. We sweated bullets perfecting every cubic inch, pushing design and technology forward. And we did it all without compromising one bit of Harley-Davidson’s unique styling.
Why does one dirty fuel injector affect engine performance?
And because there are several fuel injector nozzles that must evenly disperse the fuel, it only takes one dirty nozzle to influence engine performance. So any risk to the injector is effectively multiplied by the number of injectors in the engine.
Why do Harley Davidson motorcycles have fuel injection?
It is a sad day in Hogville. The mighty Harley is slowly loosing its carburetor. For those of you who haven’t noticed or are stuck back in the 80’s, a large number of the bikes coming from Milwaukee have fuel injection installed. International environmental concerns have slowly forced the change from carburetor to electronic fuel injection.
Corrected compression takes into account the point at which the intake valve closes after BDC on the compression stroke. The later the valve closes, the lower the corrected compression ratio. For an optimized engine, the corrected compression ratio should be matched to the vehicle’s application and fuel octane.
What does EFI do on a Harley Davidson?
Harley Davidson Electronic Fuel Injection (EFI) Originally introduced by Harley Davidson as a viable way to meet expected emission standards around the continental United States and improve the reliability of the engine in varying environmental conditions. Electronic Fuel Injection allows for better starting in both hot and cold environments,…
What should mechanical compression ratio be on Ironhead XL?
The lighter weight Evo XL can handle between 10:1 and 11:1 mechanical compression. For the Ironhead XL and Shovelhead, expect 9:1 to 10:1 as the maximum mechanical compression ratio on pump gas. Fuel-injected models may work well with up to a half point higher mechanical compression than the values listed above.
The Magneti-Marelli system used on EVO and Twin Cam FLH’s until 2001 and Buell XL engines is an Alpha-N EFI system. On these bikes, load sensing is determined by the throttle position. The newer Delphi EFI system used on current Twin Cam engines is a Speed Density system.
Which is the best fuel injection EFI system?
When upgrading to modern fuel injection, look no further than Edelbrock’s Pro-Flo 4 EFI Systems. Pro-Flo 4 is not just a replacement for your carb, it’s a complete engineered system providing the ultimate in performance, drivability, quality and value.
Which is the best throttle body for an EFI manifold?
Edelbrock Throttle Body Elbows are the best way to adapt LS1, LS2 and Ford 5.0L-based throttle bodies to EFI manifolds with traditional square-bore mounting pads. An internal divider optimizes flow quantity and distribution into the manifold and they can be mounted forward, backward, or sideways on Victor EFI square-bore manifolds.
Are there any misconceptions about fuel injection?
Many mechanics and most riders really don’t have a good idea on how EFI works and how the primary components interact. Misconceptions about EFI abound and the amount of bad information being passed around is high. By the time you have finished this article, you should be thoroughly confused or have a new understanding and appreciation for EFI.

What kind of fuel injection does a Delphi motorcycle use?
For 2006 HD Dyna model bikes and all 2007> later HD motorcyles, the Delphi fuel injection now operates in closed loop mode with a pair of narrow band O2 sensors. The NBO2 sensors control the fuel mixture when idling and cruising.
How does a fuel injection system work on a motorcycle?
EFI Basics. In its simplest terms, an electronic fuel injection (EFI) system is a computer controlled fuel delivery system. This electronic control unit (ECU) reads various sensors located on the vehicle and makes the determination of how much fuel to allow the engine to have based on this information.
When did Delphi start using fuel injection on V twins?
You can be sure that it will not be many years before all V-twins have fuel injection as standard equipment. For 2006 HD Dyna model bikes and all 2007> later HD motorcyles, the Delphi fuel injection now operates in closed loop mode with a pair of narrow band O2 sensors.
What are the specifications of a 2006 Harley Davidson Softail?

What to do when your Harley starts to misfire?
The bike would start at high idle and then slow to a stall. We then did a “wild” code check on the motorcycle and got a code for the Powertrain), P1356-no fire at the rear jug. We fixed the wire at the coil, and tried to start the bike again with the same result.
What to do if your Harley Davidson is not starting?
If you only have spark on the front cylinder, swap plug wires (front to rear, rear to front ). Now see if you (only) have spark on the rear cylinder. If you do not have power to the coil; Use a small jumper wire and power your coil directly from the battery. This will will bypass your harness and switches.

What kind of EFI system does a Harley Davidson use?
EFI systems that sense engine load by the use of the throttle or TPS (throttle position sensor) are referred to as an Alpha-N system. EFI systems that sense engine load by the use of a MAP sensor are referred to as a Speed-Density system. Harley-Davidson has used both types of EFI systems on its vehicles.
