Re: plug wire
In ten years of building and riding I've only had one CDI fail. I maintain that most of the ignition problems seen are the result of that plastic spark plug boot which both of those links show as part of their system.
GET RID OF THEM and use a boot made for automotive use. Those heavy plastic kit supplied boots are JUNK!
