Installed and immediate difference across many of the characteristics I've read pertaining to an Ivan Flash:
idle is still 1100rpm except now it sounds quieter and smoother
throttle has no lag and smoother roll up
gear shifting is smoother? easier, better matched to rpm
acceleration is faster, higher
bumping over the engine with start button is nano-sec faster and immediately humming.
What gets me most is realizing how crappy I was running my bike this last year. I know the battery contacts previously were solid, saw no probs with lights on, but never measured the voltage while running. Now happy to report a solid improvement. All things consider, it's was the same price as Ivan's flash, which I'm still going to do one day. Thanks for the suggestions, and the nudge this forum provides.
