what kind of camshaft are you thinking of?
Most tuningcamshafts i have seen (takagawa) will give more Hp but then the maximum torque comes at a much higher Rpm, forcing you to drive in a higher rpm
These are usually not very fuel efficient.
The beaty about the c90 and the anf125 engines i think lies in the fact that you have maximum torque at relative low rpm. the stroke is more than the bore of the cilinder
and the camshaft is also designed for this.
I think long stroke engines are the best choice for fuel efficiency.
The are becoming scarse.
