Hi all, i am wondering if it is possible to make the mighty boy from its stock 3 terminal ignition coil and put a stronger coil on being a 2 terminal. is there a way to convert this?

Thanks

Yes you can upgrade the coil, but it needs to be a specific model to work with a ballast resistor setup (9V 3ohm).
If you stick any old 12V coil on it you will burn out the points in no time.
Alternatively you can upgrade to electronic ignition and use a standard 12V coil as used on most modern EFI motors.

Thanks for that info

i have a .8ohm resistor from the previous owner's setup but it began to sputter then backfire when throttle was applied so i parted out my other MB (With 3 terminal coil) and runs perfect. so im not sure whats wrong there with the 2 terminal setup
