What is the diffrence between a '76 500cc f/c twin and '77 500cc f/c twin? For some reason the CDI boxes aren't the a '76 box won't work on the '77 engine ( engine would miss and back fire a full throttle,top RPM was only 3000?) Also what is the Hp rating on a '77 500cc f/c twin and top speed on a '77 Panther 5000?
