Hi Steve,
I tried to reply using the personal message board here - it kept timing me out.
Here's my centerstand drill.
Obtain and use the optional sidestand offered by the host. Start the drill on the sidestand.
Using the right heel, push down the centerstand lever arm to contact the ground and center the bike. Right heel on the rounded pad at the end of the lever.
Using right hand, pull up on the passenger hand grip and use the left hand pulling back the left side handlebar.
Put full weight on the right heel by raising left foot off the ground, straighten the right knee and tug the hand grip and handlebar the same time.
The bike will roll back into place.
Make sure the bike is level or slightly nosed uphill to make it easiest.
Good luck!
Mike
