Well i had some time on my hands today so the first thing i did was throw the stock shield back on and rode around a while. Wow I really hate the stock shield. The shape of it is just not functional for a 45 degree slightly misty ride.
So the second thing i did was stop at Menards on the way home and bought an 18 tooth jigsaw blade.
When i got home i put my 20" Cee Baylies shield back on and marked 1 1/4 inch off the top with a sharpie. Taped over the line I made( right on the shield), then traced it again on the tape. Took a deep breath and started cutting. Everything was going perfectly until i got about 3/4 of the way done, and in the middle of a smooth cut, the electric cord got caught on the mirror and the saw came to a screeching halt. What it did was studder a bit and my smooth cut now had a slight dip in it. Oh well, fixed the cord and finished it off.
Once it was cut i used my palm sander and a fairly aggressive sandpaper for the first 100 passes. It took a while but finally got the "Dip" out. Once i was happy with that i took 400 grit wet dry and using my fingers slightly curled finished the edge.
The last step was to take Laquer thinner on a paper type rag and rubbed the edge to take out and "melt down" any left over imperfections. Now i could rub my fingers over the edge and its as smooth as the original was.
the very last step was to use my Meguires plastic buffing kit and finish it off.
Sorry no pictures of the process because once i got home i just had at it !
very happy with the results.
And the reason for the cut down was that when the shield was fully retracted i looked right through the lip. I hate that. When its warm enough to have the shield down I want to look over the top of it and have the wind in my face, but still have the protection when i put it up.
