Well it sounds like you are starting out right. You have a basic rider course under your belt. You have some experience with motorcycles. Now you just need to find a big empty parking lot and get used to the bike. Get a feel for the clutch, steering and leaning, and braking. Take it nice and slow, have fun and get comfortable with the bike.
What you will learn with the Big Dogs, they are a blast to ride. But you have to be comfortable and confident in your abilities to do so. The more you ride it, the more comfortable and confident you will be with it. The more comfortable and confident you are with it, the more you will ride it. Then next thing you know, you are at Sturgis or Bikers and Blues BBQ's, or Redwood or wherever, just having a blast riding!
