It wouldn't surprise me one bit if the f.i. 420 makes more power than a carbureted 500.
I have two friends with stock 420s and they roll!
I also know two guys with TRX450 racing quads. One carbureted, one fuel injected. The carbureted one has a jet kit, a pipe, and all kinds of aftermarket go-fast goodies.
The fuel injected one is bone stock and will absolutely smoke the carbed one. That's how much of a difference f.i. makes.
