Not sure what I'm doing to induce this but from time to time when I do a wheelie my front end wobbles from side to side. One person told me it's the rpms on the bike causing it to wobble. Another said that I need to put all my weight on the pegs and not sit but it still wobbles. I can wheelie a few hundred feet without the wobble but that's only if I keep it high enough where I've got to keep accelerating to keep it up. When I get it high enough where I don't have to accelerate to keep it up it wobbles and I don't know what I'm doing wrong if anything? Anyone else having this problem or had it?
