Take your time, do it right.. The screws holding the stator in place can be really difficult to loosen, an impact driver will be your best friend if this is the case.. I'd consider a bit of threadlock on those screws... You do NOT want them loosening. A bit of silicone seal on the grommet where the 3 wires exit the case would help prevent any oil seepage there. If I was doing the job to my bike, I would take a really close look at the 3 wire plug that connects the stator to the voltage regulator. If you see ANY sign of corrosion or melting here, I'd hard wire (solder) these 3 wires, and remove this potentially troublesome connector. Corrosion causes heat, heat melts the connector. If you aren't a good solderer, use Posi Lock connectors, they are as good, and removeable. Be sure to insulate whatever you do with heat shrink, if you remove the 3 wire connector. The 3 wires have no specific wiring position, any stator wire can go to any regulator wire. If you really want to do the most efficient job possible, run the red output wire from the regulator directly to battery positive terminal, and the black to negative, being sure to get good connections where you have to extend these wires. Get a couple of those little wire grommets to attach the wires to battery. What it all boils down to is be sure you have the best possible connections everywhere in the system. Check the MOSFET voltage regulator info here, that really is the way to go if you need to upgrade or change a voltage regulator down the road...
