Looking for advice and experience with faulty ignitions.
I've been stranded a few times this month by an intermittent problem. The bike runs fine, but then I park for a short time and it will not start again. There's no spark and it's not a problem with the spark plug (which is a nice tan colour). I let it sit overnight and the next day it works fine like nothing was wrong.
I followed the ignition checks in this guide and all was within the acceptable range:
The guide recommends replacing the CDI when the bike passes all the other checks. Yet, I suppose it could also be due to a faulty ignition switch.
I'm fine with replacing the unit, but I'd like to be reasonably sure that the CDI is the source of the problem so that I'm not stranded somewhere again.
