Lately I've been pulling my stand up wheelies really high. To the point where I can maintain my speed. Now that I'm pulling them up that high, I'm starting to get crazy wobbles in my rear wheel and I'm not sure if it's something I'm doing wrong. The rear wheel will wobble enough where I have to put it down or I'll probably eat it.
I do the stand ups with my left foot on the rear peg.
My rear tire psi is about 36 when hot (the tire calls for 42 but I like it a little softer)
I'm doing about 120km/h when I find my balance point.
I know I should slow my wheelies down, I'm still working on that. One thought that occurred to me is that my rear wheel could be bouncing around in the grooves in the road.
Constructive advice would be appreciated
