I just bought an 03 Pro X 440 and I'm picking it up tomorrow I was just wondering if there were any common problems with this sled that I should know about. And I have heard you mix the premix at 32:1 but what oil is that with I usually run Amsoil because my dads a dealer and gets it cheap. My buddies all run the "Saber Professional" Amsoil. thats says 100:1 though. Just looking for some input. thanks guys. I'll post pics when I get it home tomorrow.
