2016 RS Vector snowmobile stalling problems

[mitchellorr]

I have a 2016 Rs vector in which when I start it will idle absolutely fine for about 10 seconds and then the idle will kick down till like 700 RPM and then die. Upon trying to start it back up it will have a trouble starting unless I give it a little bit of throttle and then it will fire back up (no throttle now) and it will idle normal and then about 10 seconds later kick right back down to low idle and stall. Even after the sled is warmed up it will do this. Cruising down the trail about 60mph (running fine) if I abruptly let off the throttle it will come to a stop and then stall. It will start right back up normally but if I give gas and suddenly let off (usually) it will not idle unless I give a little throttle.

milage?

About 6400 and the spark plugs have already been replaced.

that is pretty low but the 3 hole motors are known to need the valve shims done sooner than the interval in some cases.

Pull the valve cover and check valve lash.
Had mine done between 6000-7000 miles.
Was acting up for a year before I had the valve lash adjusted.
Runs and starts great again!

TORS problem? Letting off the throttle quickly is a clue.

Took it in to Chippewa motors and they fixed it for $1100. Valve shims and exhaust clamps. About 200 in parts the rest labor.

Thats what I paid my dealer to our vector.
Its a full days job.

Correct 8hr job to tear down the sled and put back together. They did good work.

Ouch, that sounds painful even if justified. Are you the original owner? What did you run for oil?
