When I was tinkering with this idea with my 360, one of the major hurdles was the electricity requirements of an EFI system versus how much power the alternator is capable of producing. The Honda twins are already a bit anemic in this area, and adding an EFI setup is probably not going to work without some other changes.

Some of you may recall my stacked alternator idea (pics attached), but lately I've been leaning more toward using an external car alternator attached to the final drive. Using a large battery on the bike will allow everything to keep running at idle, and once you get back up to speed, the car alternator kicks in and charges things back up.

Something like this, perhaps?

I like that idea of stacked units. What made you not continue with it?

 I figured the use of a 16ah lithium ion battery would help, even if it runs at a loss it'll take a while to go under 12v. Then just pop it back in the charger.

I was worried about the extra weight coming off the crank. Additional wear and tear as well as the performance implications of the extra mass were both considerations. It would also be the first contact point in a high lean to the left.

The weight on the crank makes sense. I'm thinking of putting a call into ricks, perhaps they can lead me towards the direction of a different stator and rotor that I can make fit. I have a hard time believing there isn't a different stator out there that will work. Or, possibly having the factory stator modified.

Three phase conversion is on my todo list, one of these years.

I've tinkered with it on and off, but haven't found anything off the shelf that will work.

want to make a prototype for a 450? lol

Well... the nice thing is if we can nail it for a 450, we get most of the other Honda twins for free. :)

I do have a 2014 cb500x wire harness that is set up for a modern stator and R/R. just sayin  ::)
