THANK YOU! I miss riding my NX. TNTmo, if you WANT this, PM me...i don't want to bid ya up That mostly reflects a CDI issue, and since you are getting the 'no spark'...it's almost certainly the CDI.. The issue described early in the thread, showing the 'tach jumping'... it's NOT the tach jumping when you turn the key from 'off' to 'on'....it's when you have it turned to 'on', and you hit the start button... while the engine is turning over, if you have a good CDI, you will see the tach needle pulsing while the engine trys to start. if the engine is turning over, but the tach needle remains motionless...the CDI is BAD... Simply turning the keyswitch from 'off' to 'on' will make the tach jump(usually), even if the CDI is bad.. The CDI test isn't simply turning the keyswitch, it is more 'monitoring the tach' while trying to start the engine..
