When did the Polaris Indy 650 EFI come out?
To build pre-production excitement, Polaris introduced the 650 RXL EFI as a limited build model the previous winter. Polaris would use that same marketing idea the next season as the production Indy 650 RXL EFI gave rise to a twin cylinder limited build model — the Indy 500 SP EFI, which first appeared in January of 1991. But, that’s another story.
What kind of fuel system does Polaris use?

What’s the difference between fuel injected and carbureted Polaris Indy 650?

What kind of engine did Polaris have in 1991?
