It's pretty easy to drag a foot peg in a tight turn on my FJR - especially on roads that have an adverse camber (banked the wrong-way).
What is the proper response when you drag a peg? Do you straighten out and stand the bike up a bit? Do you touch the rear brake? Do you clench your sphincter extra hard, apply the throttle and see if you can create an impressive rooster tail of sparks?
