When did Harley go to Delphi fuel injection?
With all the changes in 1999-2000, things were quite at Harley-Davidson for a few years, though in 2001 they switched to a better, Delphi EFI system on the bikes that were injected. 2001 was also the first year the Softail line was available with a fuel injected motor.
What does sequential port injection mean Harley-Davidson?

Is sequential fuel injection better?
As a general rule, most of the benefits of ‘going sequential’ are in the fuel economy and emissions space– there is generally no significant performance difference with a sequential system over a batch system unless you use individual cylinder tuning.
What’s the advantage of sequential multi point fuel injection?
Advantages of multi point fuel injection system? The multi-point fuel injection technology improves fuel efficiency of the vehicles. MPFI uses individual fuel injector for each cylinder, thus there is no gas wastage over time. It reduces the fuel consumption and makes the vehicle more efficient and economical.
Why does my Harley idle so high?
A motorcycle idles high when it is getting too much of an air and fuel mixture in a low speed or neutral position. This is usually caused by the idle screw on the carburetor being out of adjustment, an out of place throttle handle screw, a bad carburetor throttle spring, or a sticky throttle or throttle cable.
What should a Harley idle at?
approximately 950-1050 RPM
To ensure proper charging at idle, maintain an idle speed of approximately 950-1050 RPM. Insufficient idle speed may drain the battery in excessive idle situations, resulting in insufficient voltage to the ECM, ignition coil and fuel pump (which can result in a variety of operating problems).
What information is strictly for the Magneti Marelli injection system?
