With the way the charging system is designed on these bikes, the stator puts out way more power than what is needed by the bike. The RR takes all of the excess power that is not needed and effectively shorts it to ground. This means that no matter what you pull for a load, the stator output does not change. and the higher the load on the system the LESS heat in the RR. It is kind of counter intuitive and hard to wrap ones head around. This is all fine and good until you start to ask the system for more power than it has available to give, that is the point where things really start to get hot and fail. If you get into that point, you will be going thru stators, not batteries.
