Not sure what you were exactly asking?
Generally building a fuel injection system is the same process than any other bigger upgrade project. Decide what are your goals, what are existing parts in the engine, how much money you want to spend and so on. Then figure out what you will need to reach your goals and make the system working with your engine.

I have been doing several bike installations with various Megasquirt ECU versions. Mostly for boosted engines but also for normally aspirated engines. MS2 based ECUs are fine for basic use and MS3 based ones offer pretty much everything even for demanding race use. But nowadays there are several other quite cost effective ECU brands too.

For throttle bodies the most cost effective solution is to use parts from some EFI bike. There is quite good selection of different sizes etc. so you can probably find suitable ones for most of the cases. But if you need squeeze out every last pony out of some +1600cc ProStock engine then those Lectrons might be viable option.
