I was really having a hard time with the wheelies and thought my 600 just didn't have the power. Was I ever wrong. I was just being a pussy with the throttle, so I started rolling my wrist as far forward as I could before griping the throttle. This way I could give it a lot more gas and still have a comfortable grip on the bike. That made all the difference for me. Now I can pull wheelies with no problem. If you are having problems with the wheelies I would try this method and save yourself some frustrations.
