Welcome to the forums. If you can post the tenth digit (letter or number) of the VIN, I can tell you the year. The VIN is located on the front of the frame on the crosspiece between the two vertical frame rails if it is the '97-'11 Recon 250 model. If it's the '85-'87 Fourtrax 250, it's located on the round tube that the front suspension arm attaches to, at the front of the frame, down near the bottom.
Also im having an issue when the key is off and i connect my battery the atv immediately starts trying to turn over.the only way to make it stop is disconnecting the battery what could be the promblemI have a Honda 420 rancher whats the year model if the tenth digit is 0
