hi, and welcome . that's definitely a ca160. they are great bikes! the 160 is more uncommon than the 150, and a much better engine. it has 4 main bearings when the 150 only has 3. the vin# is
under the left side cover, almost back by the tire. you should spray some wd-40 or pb blaster in the spark plug holes to help loosen the rings, and soften any oxidation that might be on the cylinder walls. do you have the chrome tank covers?
