Well Im a pro but I can relay me personal experience with my wheel alignment. Mine was toed out over an inch when I first measured it. It was never hard to steer but would dart from side to side. I was always fighting the handlebars trying to keep a straight line but it was never hard to turn in that sense. When I made the first adjustment I got it to 1/2" toed out. I tried it there and it was much better but I knew I could get it better. Last time I went to zero and now its great. I have never been toed in.

 

Check my toe-in using Nyroc's method. I only had 18" of length beyond the front of the tire to measure. At 18", I have .05" of toe-in. That's 1/20" for you fraction people. I'm leaving it alone for now. That's pretty darn close to zero. I'll see how the ATRs deal with that on Saturday.

I'm having the same problem with my Dirt Devils, And the good folks in the forum suggested the alignment thing to me also. I wouldn't think that it was that cause my bike is new only 29 hours on it, and didn't start the shaking till i changed tires . I had my stock tires up to 67 MPH and smooth as silk. So i'm thinking that its just the tires are out of round . Seems like no matter what brand you have most of them have this problem
