I bought it last October, and it has less than 3,000 miles. I charged and put the factory battery back in it, started and checked the voltage. It never increases when revved to 5,000-6,000 rpms.

are you checking pre R/R or at the battery running? should be a strong 12V at battery when not running, strong 14-15 when running, then at the 3 leads off the stator you want a 50v or so at 5000 RPM

Apparently, you shouldn't use lithium batteries with factory rectifiers on Suzuki motorcycles. Rick's makes one that is compatible with lithium batteries.
