Figured I'd start a thread on this as I couldn't find anyone with this R/R on the ST. As I'm about to go on a trip to fairly warm countries I decided to upgrade the regulator with something that would hopefully help with keeping the stator alive. The bike got a new stator 10k km ago.
Got a used Shindengen SH775 for something like 50$ and half of that was the shipping cost to Poland. It's missing the metal backplate but I'm not gonna complain for the price.
Mounting was easy. It fits the stock mounting bracket. It protrudes a bit more towards the inside of the bike but no interference issues. I cut the stock R/R wiring and added simple connectors that fit onto the new R/R.
Stock was running at 14.1-14.2V at all RPMs but I noticed it got a bit more fluctuation once it got hot. SH775 runs 14.2V at idle and 14.5V at higher RPMs. I've noticed it fluctuate a little (14.4-14.6 ) when there's a sudden change in charging conditions. I don't know how it's on other bikes but on the ST cooling in the area of the R/R is pretty bad. On this bike SH775 runs rather hot. I considered the SH847 but didn't want to modify the mounting bracket.
I'll write a follow up after the trip.
