The problems started about eight years ago, and I had a dealer replace the stator and regulator/rectifier. The next time it was just the R/R, so after reading on some forums that the OEM unit was prone to overheating because it wasn't finned, I tried a CBR900RR unit. When that didn't last, I replaced it with an aftermarket unit, followed by a new aftermarket stator a year later. Now, that combination has failed! The plug into the R/R has several burned contact points, and when I check the stator voltage right from the plug, the best I get is 12 volts. I will be replacing the stator and R/R again, but would like to find a way to avoid this in the future. Any ideas?
