I think a guy on ADV from Venezuela bought one and was going to install it on his F800GS that kept burning up his rewound stators? Not sure what happened to him.
Still here. the compufire works fine, but I did only 3,000 km on it so far (I have a new Xchallenge to play in Spain
). Time will tell, but looks fine to me, works a lot cooler than the oem regulator, can even touch it with the hand after stopping sometimes. If any interest I could take the idle and running voltages, but I have only a small shitty radioshack voltmeter.
As for this battery testing thread, thanks to Joel, this is great work. Don't worry too much about the youtube visits, I for one is more interested in reading the results and conclusions than actually looking at the experiment.
