The Stick Coil Controversy
In fact, manufacturers are today installing weaker ignition coils than ever before in powersports history, not stronger ones. What do you think "stick" coils, or as they are known in the auto world, "coil over plug" ignition coils are? Wimpy, minimalist, cost-down ignition coils, that's what! Seriously. And in their usual way, the Internet forums have everyone convinced retrofitting stick coils to vintage bikes is an advantage! But it is far from that, a disadvantage in fact. Modern engines get by with weaker ignition coils because fueling is now virtually spot-on and no longer compromised. Stronger coils are not necessary.

One last thing. Without even changing your ignition coils you can do quite a bit to "freshen up" and improve your bike's ignition performance. For one thing, doing something about the common 2-3 volt drop that is present in most vintage motorcycles between the battery and ignition coil. This means at the least, ensuring good contact at the connectors, the keyswitch, and the engine stop switch (many if not most street bikes wire their coils through the stop switch). Some folks have even gone so far as to install a relay to shuttle voltage more directly to the coil and thus recover some of that lost voltage. It makes a difference.
