Fuel injection options..

^ obviously that's theory and hearsay, but that was my initial thought

The one big issue with doing a EFI conversion on a XS is the increased electrical load. The XS alternator is really only just adequate for the stock bike, finding a fuel pump that puts out enough pressure yet doesn't draw too much power seems to have been the sticking point. I would upgrade all the alternator wiring (the stock wiring really should have been one size larger IMO) and look into the 'improved' voltage regulator offered by Geezer (forum name) though his Oregon Motorcycle store.

There has been a couple of EFI conversions done, but they didn't have turbos.

With a lot of research and contemplation, I've figured a few things now. Yes Electrical supply greater than stock will be very important. I likely see a scavenge pump being necessary to return oil to the engine with the turbo being mounted low. Also want to run a water injection system that will kick in at a medium psi level.
Of course the GM DIS ignition conversion with the megasquirt.. great electrical demands.

Has anyone done a radical alternator conversion on an XS/XJ 1100 engine to boost the electrical power to over twice the stock level?
This is definitely what I need on that front.

On your question: yes. TC has an automotive alternator off the side of his bike.
