I started doing circle wheelies to the right, but for some odd reason sense I started doing them I can't go straight anymore. It is like as soon as I pull it up it just starts turning to the right and no matter how far I lean to the left. Why is that? And one more thing, I can't get the bike to go into left hand circles.
Could it be because of too low of air pressure in the tire?

 

I feel ya there man, I cant go left for the life of me.. but I can turn right all day. Right really isnt the best either cause if you gotta put a foot down you'll loose the brake.

 

could be the tire for sure, or your chain out of alignment....

 

Just keep practicng. I posted almost the same thread a few months ago. Left turns are slowly getting there. Just keep practicing.
