so I just got a95 klf400. Same issue. The guy had replaced stator coil and CDI. We did continuity tests on the starting/charging system, and found that in the wiring harness, on the frame below the seat, there's a crimped connection with 3 wires splicing into 1. One of the wires was loose, and therefore not getting a good connection. A lot of frustration on my part, a very patient husband, and dab of solder later she fired right up. My hubby also found this problem in several places on his uncle's Yamaha.
