Hey Todd,

Sounds like fun... I'm also planning to EFI my motorcycle (FJ1100).  I'm 
currtently torn between the Microchip PIC16C74 and the Motorola 68HC11A8 
for processing.  The Microchip seems easy to get (read digikey).  You can 
get a functional demo board, programmer, and software for about $170.  I 
haven't found a source for the HC11 stuff yet (eval. board etc.), so I 
don't know pricing.  The PIC seems like a good deal, though.  

Have you thought about throttle bodies yet?
