Make sure you have enough throttle when making a right U-turn. On some bikes, especially sport bikes, it's difficult to keep enough throttle when you are at full lock going right.
Already figured that one out by nearly dropping (and saving, thankfully) my Ninja the first time I tried. To be clear I have no trouble going full-lock to either side but I definitely rely too much on dragging the rear brake which is what I'd like to fix just so that I have more tools at my disposal.
I did notice today that the shorty levers I installed on my Honda only give me three fingers of leverage instead of four like this video was talking about - I'm going to have to see how much that affects my left-hand endurance.
