BMW K1200RS voltage regulator

[PiotrK100]

Hi
Its been a long time I wasnt here, but allways come back when problems occur. Now my travel bike k1200rs 1997 140000km. I had a battery issue, just suddenly dies while driving, looks like cell colapse. Changed for new and all works flawessly. I checked and loading voltage is 13,4-13,5V is that ok? I was thinking about voltage regulator change but have no idea how to do it without disassembling to many parts??? Alternator is hiden but I do get the info that it is a possibility to change regulator somehow in easy way. Please help in that matter.

13.5 Volts is adequate for charging the battery.

The regulator is an integral part of the alternator.  It's not like some bikes where the regulator is separate from the alternator and one can substitute an aftermarket box.  If your question is asking how easy is it to replace the regulator, then the answer is "easy".  It's a bolt-in swap of a part with easy access for disassembly and reassembly.

I know K100 K1100 but in K1200rs alternator is deeply hider in frame. Manual says that you should lower engine and dissasemble many other parts to remove alternator. But I do not want to remove it just change regulator with brushes without removing alternator.

According to the K1200LT manual, the alternator is installed into the intermediate housing. The voltage regulator is accessible behind the rear cover of the alternator. Access to the alternator's rear cover might be blocked by the transmission so the rear drive, swing arm and transmission must be removed first so you can remove the alternator's rear cover. I don't see why all that's necessary. It looks like the alternator can be reached while the transmission is still in place. Maybe I'm having trouble with translation. Regardless, it still requires a fair amount of nut and bolt work.
