Reverse stalls engine

[Superego81]

I have a 2008 Polaris RMK 700 compression is at 120 on the nose both cylinders. I have else taken apart all connectors cleaned and applied dielectric grease to connectors. I'm at a loss as to why when I press the reverse button it stalls the motor. When I bought it last month I know for a fact it worked last year when I road with my buddy I bought it from. Thinking maybe just wait till the snow flies ride it like I should and see if it's still not engaging.

What RPM is it idling at? If it is low turn it up a little.

If the engine is not warmed up enough that will cause it to stall when you hit the reverse button. The TPS adjustment could be off a bit as well. Idle rpm should be about 1700 rpm.

Idle is around 1650 to 1700

Idling too high or too low, not warmed up. Also, I believe there is a high altitude procedure that changes the spark map that is changeable. I can't quite remember.

Try holding reverse button in for five seconds or so. Should change the blink rate on the reverse light indicating it has changed altitude mode.

Thanks Guys...You helped me with one of my problems...Now my 2010 IQ 600 stalls out after 25-30 yards and flashes Service Engine 5 TIMES....! New to this sled

That indicates an exhaust temperature sensor problem.
