I am not in the business and I am far from an expert, just did a lot of research on the topic on a rainy day as I know that it's a problem on the F-series bikes. The R/R you would want to buy is the Compufire 55402, it's three phase and made to handle 40 amps. About $180 delivered in the States if you look around online. I have been thinking about trying one from all the positive feedback I have read (it also lower oil temps!) but it's a bit of a pain from here as nobody in Europe sells them. If anybody wants to order one and is willing to forward one to me (of course I cover shipping) please let me know! Wiring would be very simple, three phases from the stator, then power and ground.
