I think I may be getting a Wing ('08?) in the shop next week that needs the stator replaced. He already has the part, so suspect it's an OEM version and subject to failure too.
He rides year round if the roads are clear of snow, sometimes 2-up, so I know the system is probably cranking out the watts for two heated vests/jackets, gloves, grips, etc.
I'll see if I can talk him into trying to return the original (assuming still in plain brown wrapper), and opt for a Compufire.
