Is it possible to bounce it up in 2nd without standing, or without standing all the way up? When I stand straight up my front wheel wobbles, I think its because I am holding on too tight to the handlebars. I figure if I am sitting down or not standing so straight up I will feel more confortable and not have a death grip on the handlebars.

 

Sounds like u have issues with the whole standing up thing. To get used to the feeling so can loose that death grip just practice standing up on the pegs will riding without putting ur hands on the bars just let them hang at ur sides. This will get u better accustomed to the feeling of standing up. once u feel comfortable with that u will automatically not put so much weight on the clp-ons which is no doubt causing u to get head shake. Right now u are probably putting all ur weight on the bars instead of staying relaxed and standing up more.
o yea and : PRACTICE PRACTICE PRACRICE
