Here is a better pic of the whole bike now with the new tail tidy:

It looks real nice unfortunately it will break where you made your bend. Aluminum sheet fatigues when you flex it back and forth and this is exactly what it will do from road vibration. You added major stress risers when you made the square cutout and then bent it right in line of your cut. Radius cuts would distribute stress as apposed to concentrating it in one area but this is so thin here it doesn't really matter, it will eventually break. When you make the next one I would leave the entire center section intact. More metal means less flex and longer life.
So negative nancy, should it be more like this?It looks real nice unfortunately it will break where you made your bend.

MotoChief, that would also work, assuming it clears the tail light dip. It doesn't even need to be oval at the top or bottom. It just needs a big enough hole to clear the dip. However, it'll be a lot harder to bend, especially evenly with it being 3.3 times as much material across the same area. I was surprised at how much effort mine took. You may need to rig something up to bend it so that it only bends where you want it to. 1/8" thick aluminum is quite strong.
The way mine is, it's not going to wiggle and break.
Next time drill the holes (pilot size) first then check for fit on the bike before going any further. This is the reason why in the real world drawings are dimensioned and not used as templates.So, I received the aluminum plate today at got right to work! Methodically transferred the pattern to the aluminum, used a punch to ensure the holes were all exactly as shown, cut very, very slowly so as to keep straight lines and when I was all done, not a single hole lined up. So, for all you other do it yourselfers out there, be sure to check your printer settings!
My darn printer defaulted to "fit to page" and printed the pattern out at 92% original size. :|
So I will be re-ordering the aluminum plate and trying again in the future.
Check your printer settings!
Oh man... that sucks. I did mention "It's a little bigger than an 8.5x11 sheet of paper, so you'll need to print it on two pages and tape them together, or use legal size," so if it comes out on one 8.5x11 page it's not right. Sorry you burned a piece of aluminum.So, I received the aluminum plate today at got right to work!

On a positive note, I went for a 250 mile ride on Sunday and it didn't fall off yet, so far so good. >![]()
