For not keeping up on doing them, it wasnt bad! A little shakey, as you know, but the little shakes run off with practice. This is one of my favourite moves to do of all times. I couldnt wait to learn this one when I started (even though that was just a few months ago
Incase you are wondering how to do one of these, here is a little reading info for ya =):
(Got from Superstreetbike.com)
"Same as a sit-down, you can do this one either on power or on the clutch. I'll also bounce the bike a bit to help it up. Bouncing down on the handlebars preloads the front suspension. The energy of the fork releasing, combined with the throttle input, pops the wheel up. I'll stand up first, then lean forward and bounce it by pushing down on my arms, causing the fork to compress. When the fork comes back up I'm on the gas (not as much as a sit down--standups take less power to lift up!) and pulling on the handlebars to bring the bike up.
"As the front wheel comes up, I'll drop my butt back a little bit to help it along. I bend my knees when I'm pulling the bike up, and once it gets up to about 10 o'clock I'll straighten my legs and lean back. With a standup you can hold the throttle in one spot and use your body language to control the wheelie.
"Because body language makes it so easy to balance a standup, it's easy to ride one through the gears. To shift during a wheelie, I'll blip the throttle just a touch right before the shift. When you fan the clutch to shift, it kills power to the wheelie, and if you don't blip the throttle a touch this can cause you to drop the front wheel. So I'll blip it, causing the front wheel to float a bit higher for a split second, then shift as quickly as possible. Preloading the shifter and just nudging the clutch lever will help you shift faster. I generally shift as early as possible. If you shift when you're hard on the gas or your revs are up, you're more likely to miss the shift. The sooner you shift, the less likely you are to miss the gear. But not too soon, so you don't bog the revs! Incidentally, these shifting rules are the same for a sit-down wheelie."
