My sisters got a KX80 and the power on it comes in at one rather large whack, before the powerband its not got enough power and during the powerband its got to much. So basically shes got two choice ride it fast or ride it slow. Shes not good enough to ride it fast yet is there anyway of making the power more even so she can slowly get better without going straight from slow to fassssttttt, ive heard you can change the needle to change the power characteristics.
