I have to agree with being in the wrong gear. If you were in first and just went WFO for a quick second to say 9500rpms you could snatch second and probably not pull a wheelie. You are leaning forward right??? Do it Ricky Gadson style, lean forward and bend the arms, then hit it hard.
I was in the wrong gear and had too much grip and a quick turn throttle and my BKing bit me hard. 1/10th of a second and I had a broken arm on a road course. Pulled a wheelie and when I brought it down it hit hard and I was locked up on the bars like King Kong. Mass X Speed = broken arm. I didn't drop the bike though, I rode it out to a quick stop.
For practice what I do is start in first and shift to second from WFO at say 5000rpm. Then when your used to that shift at 6000 rpm watching for tire lift. Then when you are used to that do 7000rpm, you will see the bike really snort but just take your time. Your not in a hurry to dump it. Slow and steady and you learn without having to buy plastics!
