windshield. What a difference, I ordered Memphis Shades hardware #2320-0030 and after much experimenting with spacers was able to mount the Harley windshield. Windshield is now adjustable and sits behind the headlight not in front of it. There is no turbulance behind the windshield just undisturbed air. This has been a good week got rid of alot of vibration by having the wheels balanced(which were way off) and the motor mounts and motor alignment(alignment of motor was out) and Harley had compressed the rubber on the mounts by over tightening. Took the bike to an indie, after several trips to Harley for the vibration and got the usual story about it being normal. Well it's NOT normal, what a difference, 2006 FXDLI 1600 miles!
