Last winter I was going along a lake on bare ice, On my 04 F6 EFI at 113MPH

(speedo) and the sleds shuts right down, I pop the hood, cheeck everything over,

start the sled and it all seems fine.

This happened twice on the same trip.

My sled had about 800miles on then and now it has about 3000miles.

Why would the sled shut down like that?

Im thinking that I over reved the motor and the ecu went into safe mode.

What do you think?

Think of it this way, if that happened 10 yrs ago, ya would have blown up. It detonated and shut down to prevent that

Yeah when you run the firecats across bare ice like that they get heated up and usually go into a safe mode where it will run like shit and then will shut down to prevent engine damage. Mine did it the first time i rode it on frozen trail.

My zr 800 efi would do the same thing and the problem was with the smart valves not working. I am not sure if the firecats have the smart valves or not though.

yes the firecat 6 & 7 have a safe mode or limp mode but I don't think they have and provisions to shut the motor down completely. I would lean more to smart valve in the tank sucking shut, I took my rear valve appart and removed the disk and never had a problem again. * just make sure you don't run out of fuel when your blasting across a lake.
