Don't have a 500, but I have been trying to update my wife's ZR 600 EFI and can't get her off the seat. She absolutely loves it. Excellent ditchbanger, good on trails (especially since I put jagged edge dual carbides on to help with darting), and has plenty of zip.
The one thing is to make sure to grease the drive shaft bearing on the clutch side where the speedo cable attaches. Melting snow gets behind the bearing holder into the housing which rusts the bearing. Greasing with a couple pumps pushes out the water and keeps bearing like new.
EFI is only way to go. Sleddin' with a group last yr and they'd all have to choke machines, pull three or four times, watch the choke and babysit the sleds until warm enough to shut off the chokes. I walked up to each of mine, the first pull charges the system, second fires the sled, and I go back inside until they are warmed up. I'm having my coffee before they even walk in the door.
Good luck. Ride fast, ride safe!
