How does it handle with both hands off on level road, mine goes straight, but will pull to right with a crown in the road, I set mine up to pull a little to the left to compensate for this.    Wayne

Try adding 2lb more air to right side tire to see if that helps, thats what some of the GW trikes do to theirs.  I usually run about 2 lb more in my right.

 From looking at the back of the trike, I get my  trike wheels to track to the right by moving the swing arms to the right, by adding washers. This will cause the trike to steer to the left, also add more air to the right tire, thats what the GW trikes do. I hope this makes sence.  Wayne
