Tire slipping in corners.
If it was my bike, I would want to center-stand the bike, and check that each wheel/tire runs true (no wobble when rotating). That's easy for the rear, but you will need assistants to hold the front wheel up when the bike is on the center stand, while you check that one.
If that much looks good, it may be worthwhile to re-check the wheel balancing. You may have lost a weight or two, or tire wear could be the source of an imbalance. When did the "slipping" problem start?
If suspension science is a minor mystery right now, just have a bike speed shop (usually not a dealership) check and maybe adjust your suspension settings. You may need an upgrade on the suspension system, but I'd leave that call to the experts (and maybe more than one) before spending money. At 51k miles, your rear shock may need help. Age or dirt, as well as miles, can degrade a shock. Some FJRs have a plate to protect the rear shock from road grime, which you may be able to retro-fit there.
Beyond that, bearing or bushings in the relay arm or swing arm maybe at fault, but that's not very likely, for that mileage.
Keep us posted.

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.
