Forget the serial number, just check the component codes. All the Suntour stuff is date coded, and I bet the stem, seat post, brake calipers, fork (steering tube) will also have date codes. Dating old bikes is really easy, as long as the components are original. Once the components get changed, then it gets quite a bit tougher.
