The Mamba is a awesome motor and the Cobra even better.
In fact Axe motors are the new motors released by the original Rossi company.
After the owner died hes son took over and renamed the company AxeMotorRossi.
I ran the the Black magic fro over a year and now run a cobra.
There budget engines are also excellent and the Speed and Mamba are simply awesome.
The Cobra also loves the JP-3 Pipe and has awesome torque through out the rev range and is great on milage.
