If I could have found a decent project bike, it was going to happen. Need to convert to EFI to really make it happen. And since everyone around here was stupid with their pricing the option went away. Put in a Microsquirt with a 2.5 bar Manifold Absolute Pressure sensor and maybe a single butterfly throttle that feeds to a Y where the injectors are mounted. Out of tank fuel pump with internal regulater and new coils with built in drivers and program the sucker and run it. You might need to change the cams so that you no longer have the large overlap between exhaust valve closing and intake valve opening, no sense in blowing all that air/fuel out the exhaust valve.

Getting the throttle body and making the intake runners with injector seats and fuel rail is the hard part.
