Hi from Canada

Hi guys
Thanks to everyone for posting great topics for discussion. I enjoy reading them.
Can anyone tell me who I can contact to determine what year my son's ATV is from the VIN on it?
It is a 90 CC ATV with a Loncin engine. Not sure of the manufacturer as there are no stickers or date of maunfacturer tags on the frame, cowling, or under the seat. The only identifier I have is a 17 digit/numeric number attached to the front of the ATV.
Regardless of when it was built, my son enjoys tearing up the lawn and dirt when he rides it.
Any help is appreciated.

Mark
