Getting an 06 RMK 600 ready to go that we bought earlier this fall, just noticed that the reverse doesn't work on it. Emailed the previous owner and he said it was because he changes the helix in them to non reverse helix, but I think there's more to it... it doesn't do anything when you push the button. So I'm thinking either the switch is bad or maybe it's idling too high? It idles at about 22-2250, what is the cutoff that these wont go into reverse? I've got a couple other sleds here that I'll try the switch on one of these days if the RPM deal isn't it, anything else I could check out?? Everything appears to be plugged in.
