Honda CT90 Question......................…

where can i find the VIN number on my honda ct90? looks to me like a 69 because it has a reflector in the front and triangular speedometer...also if the vin number starts with CT90-? or after CT90? last thing, where is the engine serial number located? because i go to dmv and i give them the 6digit number and they say they it doesnt appear on the computer? is the CT90 part included in the vin number as well?
