This has happened to me twice now, I have a 07 700 Grizz and both times I trailerd it while it was cold out, I couldnt get the bike to start, I had to get 3 buddies aim their exhaust on my bike to warm it up in order to start it. I really dont know if it actually helps but thats all I got. Sitting in my garage it will start anytime, its when it gets on the trailer it does this.
