First, remove the seat and side covers so looking at and getting at everything is easy. No tools required!

On the right side of the bike, you'll see the rear-brake master cylinder. On the left side will be the regulator. You'll replace that.

And from the top you'll see the battery.

Before you touch anything else, remove that battery and get it on a charger, primarily because it's probably dead (you had a charging problem, after all), but also because you don't want those electrons running around when you're trying to fix your bike.

Prepare to remove the stator. It's behind that cover.

Keep an oil pan handy, because the stator swims in oil. The magnets are going to want to keep the cover on the bike, so don't be surprised when it doesn't just fall to the floor after all the bolts are removed.

If you had removed the starter cover and unplugged the stator wires beforehand, you may be able to pull the stator from the bike, now. If not, you can do it later.

And that's what we'll do now. Unplug the existing stator wires. If it's OEM, you'll have one yellow and two whitish wires. You'll find them connected to the regulator.

Once the wires are unplugged, you can remove the starter cover and loosen the primary sprocket cover to make pulling the wires easier. They're fed through a little channel behind the sprocket cover, underneath the starter cover, and through the engine case.

Then, remove the whole assembly from the bike.

Out with the old...

...And in with the new.

This little rubber boot seals the channel where the wires feed from the engine case. The new stator may not have one, so you may have to reuse the old one.

Most shops don't stock these gaskets. If you don't feel like waiting, a hobby knife and some gasket material from the parts store will get you going. You can use the old gasket as a trace.

The new stator's wires go where the old ones left. Feed them through the channel behind the sprocket cover. It's a tight fit, but they'll go.

Bolt the sprocket and starter covers back on, and you're in business.

Now, on to the regulator. Unplug and remove the old one. It's just two bolts.

Put the new regulator in its place.

Now that everything's bolted in, you can wire it. The regulator's red wire goes to the battery's positive terminal...

...And the three yellow wires go to the stator. These yellow wires don't need to be oriented in any special way, which is why they're all the same color.

Don't forget the ground.

That's it. Pop the battery back in and start it up. Check that the voltage increases as you rev the engine. The voltage should start close to 12V and increase to 13 or 14V.

ElectroSport makes a very good replacement stator and regulator for the Suzuki GS750. These won't cause your charging system to burn out like the OEM versions.
