The CR's should charge simillar at all speeds.
Mine dropped a stator segment and was charging low at idle but "almost" full above about 3500rpm.
New stator...14.3 at idle..while driving..from 14.3 to 13.4...up and down in a wave motion, just like the original stator used to do.
1. That's fine...but Buell used a heat sink compound between the frame and the regulator. The subframe is the actual heat sink.
1A. I installed a computer type cooling fan to blow down onto my regulator. .75 amp draw, forgot the rpm, but it blows pretty hard..
I turn it on when in traffic or hot days.
2. If you are speaking of the sensor that's attached to the back of the airbox..that's correct. It just sits there.
Should be pointed down though to keep water and other crud out.
