I'm actually finding the opposite. It's only happening at maximum speed on open roads. I guess due to the higher output of the alternator at constant high speed. The BMW R80 charging system has books dedicated to understanding it though.
Most of the finned reg/recs aimed at retro fitting on the R80 specify not suitable for lithium batteries. I'm sure manufacturers are covering themselves and they may be better than existing but it seems they need to be operating in a small range of output voltage to work with lithium while also having very small amounts of ripple.
Airhead
@Picard
It's in slow/stationary city traffic with little to no air flow that problems might occur, which is why it's best to heat sink it to something metal with a lot of heat dissipation potential. As lynx said, the finned reg/recs are best too.
