I hate to sound stupid but here goes on my 2004 rancher there is a lever on the left side of the handle bar the owners manual say it is the front brakes when I pull it nothing happens,also when I release the parking brake I have to push the lever forward for the brake light to go out,it should spring forward ,if the bike sets moore tha 30 minutes you have to choke it.now the good part I crossed a log today the left front wheel was off the ground and spinning full glory the right front would not move ,(it was in 4 wheel drive) in esp are auto mode,so when I got across the log I eased up to a tree still in some pretty soupy mud and tried to spinn the tires the tires would not move in esp,auto,2 wheel drive are 4 wheel drive any advice on what I am diong wrong are to correct the problem would be appricated
