Does anyone have any specs or info on the 2001 MX Z x 440 Racer?? One person told me it was NOT oil injected, and you had to use 110 octane gas. Someone else told me it had oil injection and 91 octane gas was fine. I want a REAL answer from you guys on here if anyone knows. I just want to know if it has oil injection, and if you can use 91 octane. Also, any other specs would be appreciated, thank you.
