rpms and hp figures are lower for the forklift engines
Parts are probably not designed for auto rpm redlines.

Whats interesting is the cg13 all alloy model is available with a
carby setup like some auto markets overseas and this engine complete
is 80kg and the a15 103kg, I know which one i would if aiming
for higher rpm output in a light car with 23kg advantage.
