Maybe so, but I doubt it.
We specialize in EFI bikes and get higher numbers then most with them, not in some piece of literature, but on an actual dyno and on the road.
Discussing EFI and discussing EFI for a big twin Harley are two completely different subjects.
You have the built in limitation of engine (and to some extentbike) configuration.
It is very difficult to get clean vacuum signals on a common crankpin 45 degree two cylinder engine with the associated very uneven firing order and where the intake charge has to make sharp 90 degree turns without the possibility of fitting a large volume airbox. Now add that the Delphi system is primarily MAP dependent and you might begin to understand the problem.
Look at the throttle body arrangement on a Ducati where the intake charge and the injector has a direct shot at the intake valve and there is all sorts of room for an airbox between the V and you begin to see the differences.
When you are dealing with a fundamentally old fashioned engine configuration, regardless of how smart you might want to make it, simple might just be the ticket.
Don't get me wrong, I like working with EFI bikes and they make me good money, y'all go and buy one. I still like a carburetor on my personal bike.
