I've noticed that rolling on the throttle in a tight curve leans the bike over and tightens up the corner and backing off has the opposite effect (bike stands up and goes wider). If the rear wheel starts to slip out, should you a) roll on the throttle b) back off the throttle or c) maintain the throttle. I can see a) would shift weight back to the rear tire which would help traction but increase torque which could lose traction. b) would shift weight off the rear tire and pretty much have the opposite effect of a). c) seems like the "ride it out and hope it fixes itself" theory.

I'm talking about a relatively slow turn too, like 10-15 mph. Like making a 90 degree at an intersection or going up real tight hairpin turns. Not race track stuff.

Thanks

Iron...this has happened numerous time to me at higher speeds, usually on new, slick road surface 'repairs'.
I would not use the throttle (consciously) by itself, but try to stand the bike up slightly by countersteering in the opposite direction.
In a tight right-hander, I would either pull back on the right bar or push on the left to get the bike upright slightly, and maintain the throttle as best I could. I'm sure I let off the throttle somewhat, but not consciously. If you are going slow, panic, and chop the throttle, you risk going down lowside. Too much juice can deliver unexpected torque to the rear, as you say. This will not be good....

I've always tried to steer out of it, adjusting throttle as needed to help maintain lean angle....
