I hear that a laser alignment makes a big difference (my dealer doesn't do them), but will it make enough difference to boost my confidence in a turn? I don't see how that could happen, though; the basic engineering should get me through a turn.
FWIW, our machine was pretty sketchy too when cornering. Also, it buffeted at highway speeds around other vehicles.
It was not practice or getting more accustom to a three wheeler, it was sketchy.
You asked, how can a wheel alignment help? For us it was the single greatest improvement.
If the Spyder is aligned, or most vehicles with two front wheels for that matter, you deal with at least toe in and toe out. The Spyder also suffers from bump or lean induced steering geometry changes, known as bump steer. The Spyder also, with it's Go Kart type steering has Ackerman effect. This is where the inside tire turns more the the outside, a good thing.
With toe out, a vehicle can be darty in a straight line, and even difficult to go straight down the road. With slight toe in, the vehicle will tend to track more straight.
With toe out, as you enter a corner (and I won't consider any leaning effects), and begin to turn in, the outside tire is still pointed to the outside of the corner, while the inside tire is turning a tighter radius. As you turn more, the outside tire will go to straight,and then begin to turn to the inside. The point where the outside tire tire towards the inside of the corner, the machine will dart towards the inside of the corner. Your reaction will be to steer outside, resulting in possibly an erratic line through the curve.
On our machine, I took a wild guess and cranked a tie rod. Without me saying a word, the wife noticed immediately the difference. I could still otice some tendency to weave, but it was better. I did make another adjustment, making the machine night and day better from how it was delivered.
Later I installed a BajaRon sway bar. This made cornering better still, but most importantly, stopped the buffeting at highway speeds.
Hope you get it sorted out, certainly no two wheel motorcycle, but still fun to ride when dialed in.
