I had a 50cc pocket bike with a CVT transmission. What I did was, hold the front brake and rev the bike up, then pop the brake out. After a few tries of adjusting throttle input, I got to where I could pop it up and ride for a few feet. Be careful though. I learned first hand it IS possible to 12 a stock pocket bike..
yeah but if the CVT doesnt have enough pressure (speed) to engage it, when you wack the throttle and pull up it does nothing except start to engage. It took me some getting used to with the timing of the cvt but before I pulled the stock 50cc out I could do them very easily...now I spor 125cc and bringing the wheel up is not the issue....keeping it down is
1st gear has a lot of engine braking so just crack the throttle, sit back a little and it will come up. 2nd gear is smoother with less engine braking but cover the rear brake to keep from looping. I could do highchairs no problem in second on my stock fiddy.
Just pull on the bars and crack it open in 1st. You have to time it right though. bringing it up in 1st is easier if you are going really slow. When i do it, im barely creeping along. Wheelies arent too hard on those. Now stoppies take a little more work.
I have a clutch on my crf50 but I just use the throttle for wheelies. Lean back and crack it and it will come up. I just kept driving back and forth down my fathers street practicing till I could ride em out a few feet. So much fun, too bad mines in pieces down in the basement. I tore mine down to paint the frame and stuff black but it came out like crap and need some warm weather so I can spray it again and put it back together. 50's ROCK
