I wonder how many other EIs have failed after 10 years (Note post #1 here). So far, I've never replaced a Tri-Spark single/twin, but have replaced five failed EIs from others. The only two Tri-Spark Tri-0005B returned to me are running in bikes today. I've never had a Tri-0005A or Tri-0006 returned. I've sold/used 168 of the single/twin and many Tri-0002 for triples.
