Looking at the bore/stroke it is no NR model. Also 16.20 x 17.00 does make 3.504cc which is not alowed. But 16.20 x 16.90 is the same as the Sirio CL7B engine which is possible because the Xenon series were also made by Sirio.
I noticed that too. The case looks Sirio but the carb doesn't. But then they have that NR clone orange carb on the Sirio based Xenons so my guess would be Sirio.
