I've had issues with Honda, Yamaha, and recently with Suzuki electrical systems, usually starts around 30,000 miles. Makes me appreciate the ST1300 alternator system, zero problems even at 70,000 miles. Any bike/ATV that uses a stator set up has issues if you keep it long enough. But, I have to say the magnets coming loose is a stupid design.
Suzuki does not make regulators, maybe you should try a better model, different brand etc. Although I've never had a R/R fail, I'm happy with my upgraded series type because the voltage is more steady and higher. I personally do a full electrical check out on stator bikes if the voltage drops below average. At least its easy on the V Strom, easy to pull the cover an look during a chain and sprocket change if the magnets are OEM. My magnets all touched and the stator burnt in two places, but the bike had extra lights on it when I bought it used. I took them off.
I vote for air cooled alternators on ADV bikes, much more durable.
