I purchased a 1989 KX250, afterwards i learned the ignition system (stator, rotor, igniter, and ignition coil) was replaced with components from a 1984 kx 125. The bike starts and idles fine but has no power, is the problem the ignition system swap the problem? and if it is is there any place i can find the correct electrical parts for cheaper that stock because it would cost me over $1000 to replace those parts. Thanks
