This past Friday I was out riding and it was very cold. (-30) My eyeballs were freezing up!! Anyways, my brother-in-laws F7 and mine would both cut out all night. Our machines ran fine for a couple of trips before this one. Once Sunday arrived and the temperature warmed up a bit both of our machines ran great. I asked my dealer about the safety switch problem that Cat has had on many sleds and he said that since it has EFI that it wouldn't have this problem. Is this correct? Has anyone else had this problem in really cold weather? Could there be a chip for the EFI that has to be changed for very cold weather kind of like when people change their jets for different conditions?
