      A week ago I could not even get close to starting it. But now I adjusted the valves (exhaust valve was not closed). i got it running but would not run without choke. i adjusted the float because it was to low tried starting it up again and it would not even start. So i went back and looked at the valves and the valve was now open again so i adjusted it and it started right up and ran perfect without choke. So i put it all back together thinking it was ready to go. Started it up and let it run for a little bit. i turned it off and tried starting it again there was NOTHING. took it apart and there was 0 compression and the exhaust valve was open again. I am completely lost need help PLEASE!!!:aargh:

      I have a 2001 Yamaha Kodiak 400 (YFM400FWAN©) On a recent hunting trip a problem popped up and I hope someone else has experienced this, so that I can learn from them instead of going on my own hunt for an answer.
      The Problem:
      On cold days (sub 25 degree) I choke the Kodiak and it starts instantly. It revs up and runs on "high idle" without any problem. However when I return the choke lever to its "normal" position the ATV continues to run and a very high idle. I cant put it into gear until the idle comes down, which it doesn't. In order to use the bike I have to shut it off and when I restart it I must place it into gear before the engine gets a chance to rev up. It then returns to a normal idle and the machine behaves normally. This only happens on real cold days but it is a problem I want to fix. Can anyone offer some help?

      I have a 2005 Fourtrax. It wouldn't shift and the display was blinking three times so I replaced the angle sensor. It initially worked, but now the display is blinking eight times. I did not reset the computer after replacing the angle sensor. Do you think I need a new control motor? Anyone else have this issue after replacing the angle sensor? This is a great site. Thanks
