Thanks dewski. To anyone in San Diego, I have a bunch of material left over from this that you can have in exchange for some beers!

Not sure how those screen protectors will hold up in the rain but I got some cheap anti-glare ones from eBay. Should be able to make like 6 of them.

Great DIY..One think I have kept wondering is how much does this "protector" actually cover? most rocks are so tiny that they will fit in between the honeycombs in these protectors, but at the same you can't have them be so tiny since the radiator won't get a good airflow..thoughts? I guess you gamble on the rocks hitting the protector and not going through..?

It's a trade off.... best protection = no holes, best airflow = "all" holes or no screen.
 
With time most radiators will get damaged and plugged up... A correctly sized radiator will have enough capacity to allow for that loss of cooling/performance. Most people don't touch their radiators and they last the life of the bike, unless their damaged in a crash.
 
If you notice the bike running hotter and/or are very inclined to maintain the radiator 100%... It wouldn't hurt to, every so often, hose/clean/blow out the radiator fins. Bent fins can be straightened out with a "radiator comb" or small flat screwdriver or pick. However a few bent fins only "looks" bad.
 
My thoughts, a screen or guard is their to protect the radiator from any large debris that could due real damage, i.e. crack a passage and cause a leak, severely damage the fins or a large portion of them. Something that would keep you from riding home, i.e., stranded.
 
I'd be happy with perforations on the order of 1/4".

Small rocks have less mass and a lower chance of damaging the metal radiator. The larger rocks would have to enter the radiator guard normal to its surface to get through and I'd say chances of that happening are very low. Solutions like these work because most of the time debris hits the radiator guard first and either gets deflected away or passes through after losing speed (so they have less chance of damaging the radiator). Probably got too theoretical with that, but that is the concept as I see it.
 
I'd be interested to see a comparison in the construction of the Evotech rad guard (or other honeycomb guard). Eyeballing it, the hex dimensions look similar if not the same...

Flat screwdriver, awl/pick, etc… I'm sure there's a comb out there that'll work.

It's been a while since I looked for one... do you know how many fins per inch the radiator is?  There are tons of them on Amazon.

Its not the fins that are the issue, it's the lack of width on the radiator that wont fit the comb. comb wont fit between the heat transfer tubes

I used a small flat head screwdriver made for electronics, came with an iPod repair kit I once got. I think a not-very sharp pocket knife would work too. In both cases you have to do each fin individually, however.

Noticed some scratching on my LCD as well... picked up a set of screen protectors: Amazon.  Good thing there were two sheets, each large enough to do 2-3 FZ screens.  My first two attempts at cutting the material with an x-acto failed.  The edges wouldn't stick and I suspect the blade left a very tiny burr.  Third attempt, I used scissors and that worked much better.  So on my fourth attempt it came out perfect.

We'll see how it holds up... If it doesn't, I have a bunch of 3M clear protection film to try.

Mine has held up so far. I used scissors as well to cut my screen protector... I will edit that into the OP.

@ryan4130 great write ups. I had planned on doing both but will probably do the display protector first. I see your template but looking at your installed protector, looks like you missed the left corner?
 
Just wanted to make sure your template is more of an exact fit for our screens before I cut
Thanks!

The template is spot on although, You will need to trim off a little more after using the template to make it fit. You want the protector to be slightly smaller than the screen.

I printed the template (to scale) on paper, put it against the screen and trimmed it as needed… I then took the "trimmed" template and cut the screen protector.

I wasnt able to find 1/4" Hex sheet metal for cheap in my area so I went to Home Depot and picked up a piece of this sheet metal and then followed the instructions above to make my own.  Most Home Depots should have it in stock and they do have other options as well.
 
Here are the results.

I have not ridden it yet since I have put it on but plan to in the next day or so.  Just letting everyone know that there are other options as well.

I also could not find the hex patterned sheet metal nearby and for a reasonable price.  I also was having a hard time masking off the parts of the bike to not get paint on them, so I just removed the whole radiator masked that and gave it a good even paint job.  Also stenciled the yamaha logo on like @nohater did.  The sheet metal I used already had the gold colored coating.  I attempted to follow the instructions by the OP but keeping everything symmetrical with this particular pattern was tough so in the end i just had to do my own thing.
 
As far as operating temps.. I installed the guard and ran it a few days prior to painting everything and there was no change in temps (usually 174-178 °F), Although I do not live/ride in that busy of an area so I have not been stopped or have had to ride very slowly for more than a typical stop at a light, so I do not know the effects of having a guard with more surface area under those conditions.

I have made my radiator guard 9 month ago and its holding fine with no temperature issues.

On the other hand, the display protector lasted only a few month until the wind started to peel it off slowly.
