I am building a reverse trike with a 1982 Goldwing and a 1970"s vw beetle front torsion bar suspension. It's all coming out fine except the steering is twichy at any speed over 15mph. When I built it, I squared up the bike on my bench and ran a center line front to back and set the front end to that so I know everything is square. I lightened the suspension by removing the smaller leafs to compensate for the lighter front end and the spring rate is comfortable. Everything has been rebuilt in the front end so all is tight.
As far as alignment goes, I lined up the front rims parallel to the rear wheel as my research indicated. I am running about 4 degrees of castor, 0 degrees camber and 1/4" overall toe in over 24". I also installed a 3/4" sway bar which makes the front end stiffer side to side so it doesn't lean very much. I am running my tires at 20 lbs, down from the 30 or so when I had them mounted. I have readjusted this front end many times but can't reduce the slight side to side wander instability to a comfortable point. I am at wits end on this. Any ideas are appreciated.
Thanks, Bob
