I haven't even started looking. Figured I'd find out what size I needed first.

I'm new to this whole EFI thing - I need to find out what size body, what size injector, how to map it all, etc.

Kinda hard to jam an injector into the main jet hole though.....

A little more info -

The engine is in a Kawasaki KLX450R dirtbike. The current carb is a flat-slide model Keihin FCR-MX40. I ride at lots of varying elevations (from 600 ft to 14,000 ft) and I am hoping that FI will make that easier by eliminating the very time consuming jet and needle changes ...

Can I assume that if I am changing from a carb to a throttle body on a single-cylinder engine that I should use the same size throttle body as the current carb? (40mm in this case on a 450 cc engine)
