Yamaha FJ1200 Project

[Sean Magnuson]

        Hey! I'm new here, and I must confess that the main reason I have
subscribed is to obtain suggestions on converting  my carbureted 1986
Yamaha FJ1200 motorcycle to fuel injection.  I am currently using the four
stock 36mm Mikuni carburetors with various jetting and slide-spring
combinations to achieve different power curves, but I'm getting tired of
changing the set-up every time I want to switch from quarter-mile runs to
highway cruising.  I've installed a four -into-one exhaust system,
upgraded ignition system,  slightly hotter cams, an air/fuel monitor, and
fabricated a fiberglass airbox and ram-air system.  I am interested in
developing as much power as I can, but  without sacrificing streetability.
Having  recently graduated, I am planning a trip across the U.S. with my
dog, Max, in-tow.  Yeah, you heard right - I fabricated a hitch and trailer
system to keep him happy while providing valuable"trunk" space.  I am
looking  for the ever-elusive combination of reliability, power, and
mileage.  I know there's someone out there who can help me, so here's my
questions:

Q: Is it best to go with a "generic" four cylinder system or a system
designed for specific displacement and rpm characteristics?

Q: Are there systems which allow easy programming via commercially
available software?

Q: Are there sources for dependable used systems - eg. small autos?

Q: While I have read and understand most of the recent postings on DIY-EFI,
I am not heavily versed in theoretical approaches.  Are there
microprocessors that can be hybridized or built from scratch by someone
(like me) with a good practical understanding  of circuit construction?

Any suggestions or comments are appreciated.
