I am planning on trimming my stock triumph windshield by about 2 inches. Anyone done this yet. My windshield hits the top of my head and is a pain at speeds above 60 mph. Currently, the only time I use my windshield is on trips greater than 100 miles.

I am planning a trip to Maggie Valley to ride in the mountains and it is about 400 miles to get there....

I don't have the cash to get a memphis shades or national cycle windshield yet, and a buddy has a shorter summer screen that he has modified and the wind is not near as bad as it is on mine.

Did it with a Triumph Tiger shield a while ago.
Mark it with masking tape and cut it with a Dremel or similar. Very fine wheel, very fast and very slowly.
Advice I got was to do it when its as warm as possible in direct sun and you shouldn't have a problem with the plastic splitting.
The plastic will melt a bit with the speed of the wheel but it cleans up nicely with some abrasive paper.
Good luck

Follow the line on both sides of the windshield with masking tape. Get the good stuff too and leave the tape on until you're completely finished. We used a jigsaw with a fine blade, working very slowly so's not to melt too much of the plastic. Have an extra pair of hands ready so that as you get to the end of the cut, it doesn't snap off and ruin anything. Once cut, we used sandpaper to smooth the edge and get rid of any saw marks. Go finer and finer in grit until you're at around 1000-1200. At that point, you can either hit it with some polish to get it to look like the rest of the edge.

My friend actually made a VERY fast swipe over the edge with a torch. Someone had told him that it puts a factory-molded-looking gloss back to the edge and it seemed to work.
