I've read a lot of misleading stuff from supposed experts on weighting this peg or that peg. Keith Code makes the most sense to me---weight the outside peg & lock the leg to the tank for the sole purpose of taking weight off the bars & preventing unintended steering input like blue03636 said. Putting more than a smidge of weight on the inside peg is awkward & will actually cause you to make unintended steering inputs when you are hanging off or when you transition. Your bike doesn't know which peg you are weighting, It only knows the location of your center of gravity.
