Got to test ride with with stick coils installed yesterday. It may be just the placebo effect, but the motor seems to be a bit smoother. More so at idle and lower RPM. There is an older thread https://www.superhawkforum.com/forum...cap-mod-32244/ discussing the effects on a dyno. Who knows?
The mod does however clean up the wiring a bit and removes a couple of ounces. Which, in my head, makes the bike better.
