I finally finished installing the National F-16 windscreen on the 77' KZ 1000 LTD. I needed something to block the wind blast. I like the basic design but the quality control could be better. I knew I would have to alter the mounting slots because of moving the front turn signals from the bars to the headlight mount. I had to open the slots up from 10mm to 15mm. I wasn't happy with the amount of vibration at the top of the windscreen and how easily I could push it back further so I made braces for the upper part.
I used some handlebar clamps from an old busted windscreen, some rubber lined 3/16" P clips and a couple pieces of 3/16" rod. I drilled 4mm holes in the upper part of the windscreen to mount the P clips. With an inch of the rods bent about 110° to fit in the P clips and the bottom goes into the bar clamps. I have used this method for other fork/handlebar mount fairings, it works great.
