Now I'm no mechanic, but I went through the same deal with mine, and after many long hours adjusting the ladder bars, I found out the truth. It is SUPPOSED to pull a tiny bit to the right, to accomodate the way the suspension is set up. It does bug the crap outa ya, does'nt it? Anyway, we adjusted ALL the tilt outa mine, and got the thing to track perfectly with NO pull in either direction, and the ride/handling SUCKED!!! After about 60 hours of testing, (and zook was even involved in helping me in person), I have concluded, without a doubt, DO NOT attempt to change the set-up, unless you have a builder of trikes available. You could have to completely tear down and rebuild/set-up the entire rear suspention, if you don't know what you are doing! Ask me, I know!! The cool thing is, your trike is infinately adjustible, for ANY configuration. But these trike engineers already drudged through all this, and, assuming the builder/dealer is good, gave the adjustment parameters to the build shops, that will prove to be the most practicle set-up, for overall ride. I was able to minimize the pull enough that I don't notice it anymore. The dumbest mistake was trying to "level" the trike perfectly, only to have it lean to the right, and pull to the right terrible, cause of the "crown" in the road. (REALLY noticable in Florida, cause they really have a drastic watershed crown on thier roads.) Anyway, I hope my errors have helped give you food for thought! Good luck with it, I know it is a bugger. jimsjinx
