You first need to spend a bunch of time riding your LT to get used to it...as far as a tight U turn, the main approach is to be aware of the speed you are traveling for the sharpness of the turn, tight being pretty slow. Then you need to keep your head up, look where you want to be when you are done with the turn, and turn. keep looking at where you want to be, not at your hands, or the windshield, or at the road in front of you, keep your eyes on where you want to end up. People have different riding styles, and I don't think one persons step by step description will suit everyone, but I know from experience that if I look where I want to go, somehow the bike follows and my body just does what needs to be done. Yea, its magic...
If you want to wimp out, just stop, put the bike in reverse, back around, put it in forward, and turn the handle bars where you want to go to, and dump the clutch...slowly...
Good Luck!! :wave :wave :wave :wave
