I bought an 03 F5 sno pro for my 90 lb girlfirend thinking it would be a great sled for her. When I bought it the guy had stored it inside most of its life and it fired right up. I brought the sled home and ripped it up and down the road for a while. Then it sat outside on my trailor in the cold weather. I filled both my sleds with fuel at the same time and do not have a problem with my 800.
SO here is the problem I went to start it and it ran fine for about five minutes as i was letting it warm up. I got on it to turn it around and it died and i couldn't get it started. Later that night I brought it to a friends house with a heated garage to let it thaw out. It still would not start. I took the lines off the fuel pump and put pressure to the gas tank. The fuel pump dribbled out gas. I noticed the line from the pump to the carbs was dry. I thought it may be air locked. Does this sound possible. So, i filled the line with fuel and it started right up. No problems. The next day we rode all day.
Today, a week later I went to start the sled to see if it would run. It fired right up for about five minutes again. and then it dies. I filled the line from the fuel pump to the carbs with fuel again and it started. The motor seemed to be warm and i could not keep it running without playing with the throttle. As soon as I take the choke off it wants to die. Now, I can't get it started at all.
What can I do to make this sled reliable????? I want my girl firend to enjoy snowmachining cause I love it do it. and if she doesn't like it I'm going to be in the dog house when im gone every weekend and she stays home cause this sled wont run and she gets a bad taste for riding??
So any help would be greatly appriciated.
