Very nice and inexpensive. I installed a similar regulator/rectifier from an early Kawasaki four. One thing I just learned is that the regulator voltage sensing wire needs to hook up near the battery. I initially hooked it up to the switched power to the coils/lights (blue on the 350). The problem is that due to the small diameter wiring used on Bridgestones, there is .5 - 1.0 volt drop in the wiring, throwing off the voltage regulation. I had a couple of oxidized connectors that added another .5 volt drop. On the Kawasaki regulator, the voltage sensing wire did not need to be switched as there was no current draw to kill the battery during storage, so I hooked it directly to the battery positive lead.
