I think you have a ES no doubt , you spoke of not shifting , angle sensor and you throwing the shift motor , all things that wouldn't have happen with a S or a FM ----- the thing that concerned me was what year is it and where was the atv manufactured for , as when they are made to Canadian specs sometimes there are differences ----- I think what happened is with the winch in place the previous owner couldn't get the correct vin for the bill of sale , so he used another ---- let's just hope that is all it was
just to clear this up, SOME ... which switch does yours have ? 1st, << (ES) or 2nd pic ? from what I've read so far ... should be the 1st pic. doesn't look like the service manual will be of much help. the more pics we have the better.
