Yes, I agree. This engine has taken a large amount of inspiration from the Aprilia GP top end, although this is using reed not rotary. I think the GP - RSA125 engines were circa 55bhp, and even the commercially available Aprilia RS125 road bike was circa 33bhp. So I don't see any problem with Salvatore hitting 40bhp using the RSW exhaust cones and such.
