I am swapping engines with a 2007 Sportster XL 883 EFI engine, does anyone have experience wiht this?
I am putting a 2007 Harley Sportster XL883 with EFI into my custom chopper. Will I need to recalibrate the computer for the EFI? Will it need to be re-timed? Maybe I am making this more difficult than it actually is, but I am guessing with the amount of electronics present, that it is more complicated than simply moving the engine from the original bike to my chopper, turning the ignition, and drive away?
I will probably have a different exhaust system than originally from the factory. Also, I purchased the engine separate from the wiring harness/computer/etc. so will it need anything more than connecting the wires?
This is a budget build. I purchased a 07 XL883 engine very cheap and I am planning on building the entire chopper for about $5k. I’m not done yet, but I expect to keep it around this amount.
Stick it in, fire it up and ride.
The only reason you would have to re-map is an exhaust and or air filter change.
**** If the engine has already been in a bike and run, the timing has already been set.
If you run an aftermarket exhaust ,you will probably have to re-map by means of a “Power Commander” a “Vance and Hines Fuel Pak” or some other performance module.
There really aren’t that many connections from the harness to the engine:
Oxygen sensor
TPS
oil pressure sender
power to ignition (and maybe a tach wire)
Alternator/rectifier
starter relay
90% of the wiring is non-engine,I.E lights ,gauges,switches etc.
