I have a 02 recon es. The battery died last year and i just left it dead all winter and went out to get it running here recently. When it died last year it was also throwing and angle sensor code. I got it into neutral with the emergency shifter and put it up. Got a brand new batter fully charged and the bike cranked right up and purred like a kitten but was still throwing the angle sensor code. I know there was a recall on these but its out of date and im going to replace it as soon as i can get it ordered. My problem is that when i tried to shift the bike with the emergency shifter when i cranked it here recently it wouldnt budge in any direction. Tried shifting it into first and reverse and cant get either one to work. Im wondering if its possible to lock one of these transmissions up from sitting for one year (i wouldnt think so) and any information to get it unstuck or if anyone knows the problem thats causing it not to shift with the emergency shifter. I am very mechanically enclined and have worked on 4 wheelers for a long time but i dont want to have to break into the crankcase of this es if possible. Any and all infor about any of my problems is well appreciated. Thanks in advance.
