Re: Side to side movement! HEEELP!

Mine did the same thing when I would run it on the street a few years ago. I assumed it was the gov-lock posi just unlocking and locking as I got in and out of the throttle. But I suppose it's possible that the suspension may have been preloaded on one side more than the other(I had lakewood traction bars on my leafsprings) causing it to pull to one side.
