Aaron. Indeed the mechanism I am making shifts timing during driving. I have no plan yet to also change cam duration, but that might come depending on the results.
Craig Vetter is doing a try out this week. You can follow his website chapter 33 on that.
On the EFI question here my thoughts. I think that the EFI delivers an amount of fuel based on the measurements of amount of air and the lambda sensor voltage.
So downsizing an engine should work with the EFI of a larger capacity engine.
I have somewhere on my long wishlist also an EFI system for my Burgman. Although with the large carburetter of the 385 cc on the downsized 300cc I run at this moment (after a first tank) 78 MPG. Probably I can improve on this.Aaron check your PM
