2012 S40 - 1400 miles.  I just rode in heavy rain for the first time with this bike, and it sputtered and stalled, almost stranding me.  This was unexpected.  I've ridden several different bikes in heavy rain several times over the last 40 years with no issues ever.  I've used Search and gotten some opinions.  I would like to ask this question a different way:  who has had success eliminating this problem, and what did you do?  I know about spraying water to try and replicate the problem, which I will do this week.  I'm just curious if anybody has had this problem and cured it.  Thanks.
