You need to lower your rear tire psi. Most stunters run anywhere from 15 to 20psi and 10psi for doing real slow stunts. Lower tire psi will make the tire to pavement contact much wider,thus making it more stable from side to side. As soon as you feel a woble you have to set it down right away,because they can get out of control very fast.

Well, I really just cant picture this. Any way to post a vid?....I mean i was gonna say stand up where you can get better balance. BUt still you shouldnt wobble that bad sitting down.

Your chopping the throttle. I was doing the same thing and I thought I was barely chopping it but as I got used to it I realized I was chopping the throttle. Also check your tire alignment. Don't trust the little notches that are on your swingarm. Measure it out and make sure its all aligned.

can you elaborate "chopping the throttle" is that cutting it on/off? thanks and i will check the alignment i didnt even think of that.
thanks

Although decreasing the tire pressure does help, I found that it was actually my hands moving the clipons side to side ever so slightly. Doing this actually moves the air around the front tire and causes the wobble. Unless, you have a stabilizer or damper on it, then it is possible that it could either be tire pressure (which really doesn't affect as much as others say), or chain alignment.

After a while I was able to just pull em up and ride em out, with full tire pressure and normal chain adjustment methods. If you are doing bp at speed (55 or above) it will be much more noticeable. Just cover that rear brake.

YA your on one wheel thats your problem

Really, how is the road that your practicing on? Is it flat or slope to the right? Just saying cause there are some roads that I practice on that will give me a wobble here and there and if your tire pressure is 30+ it may affect you while learning.

the road is flat as can be but my tire pressure was like 38 or so so im amost positive that is the prob.

Its not the air going around the tire. If your front tire is spinning it acts as a gyroscope causing it to pull to one side or the other depending on which way you turn it. After it stops spinning it wont do that anymore.

and yes chopping the throttle is chopping it on and off.
