You guys are too high tech for me. I have a 95 FLHT, with a ton of mods. I keep the rear wheel aligned, matching the axle bolt on both sides, make sure my tire pressure is aroung 40 psi, and run at 85 to 100 through a full tank of gas. I am in the rockies, so I have alot of canyon turns to negotiate, don't have a wobble. Nor do I agree that a 2 wheel vehicle is prone to wobble. Neck tension, tire pressure, alignment, tread wear, all can contribute to the problem. I run 3 different bikes, have a seeg to pick up next week, and seem to always be able to solve handling problems checking for the obvious, and I never have used a slide ruler once!!!
