If you look back earlier in this thread you'll see where
@DEcosse posted a link to an IR photo of the R/R running before and after.
I don't expect to see a difference -- the current R/R does its job, or we'd have a bunch of complaints about charging and such, just as with the early ignition switch failures.
My motivation is just as DEcosse said, the stator on this bike requires taking the bike apart to get to it, and the current R/R puts significant stress on the stator as it is working at full output all the time, and the stock R/R is just throwing away much of that as heat, and the series R/R only takes power as needed, so runs much cooler to start with.
