Rick, I think you need to re-read what Neil is saying.  Yes, its true 
that a car's charging system is designed to provide higher current than 
a bikes.  But that is irrelevant when it comes to charging and starting, 
as the current draw is determined by the object that is "drawing" the 
current, not the object that is providing the power.  So (as Neil 
stated) the motorcycle starter motor will draw the same current from a 
fully charged motorcycle battery as it will from a running car.
As to the issue with R/R's, I'm pretty sure that's due to the 
"transients" that Neil mentioned as well. That probably explains the 
issues that you talked about with the GS...
