If you are rolling to the left and are leaving with the wheels up 4-5 inches, then you need to look at the rear suspension. Since you have adjusted the bars and shocks and it has not helped, I would look at the rear spring to make sure nothing is bound up or make sure the spring perch (look at both, specifically the passenger side) is not distorted and that spring to axle u-bolts are properly torqued. If that checks out, you need to make sure the axle is square. Check wheel base on both sides and make sure you don't have a bent axle tube.
You'll find that when you adjust your bars the scales will show different weight. The 100#'s may be due to the increase in preload you gave the drivers side.
