As I really was under the impression that this engine was completely new, I did not dare to answer, but as it seems it is the same as the Mega ZX, I think you can see a difference in the crankcase, especially around the fuel ports.

If this engine really is the same as the Mega ZX, then run it with the 6 fins header and Novarossi 2052 pipe... you will be even more pleasantly surprised...
I ran my Mega DSII engine's with the 2018 and 2033 exhausts, but after trying the 2052, even more power comes alive....
