Wicked Front fender half Carbon Fiber Fender.....

As I am readying the GS for RMAR in Silverton, CO next week, I needed to make a front fender half, to protect the radiator. Actually I have had no issues with the rad, except the fan tends to seize, with all the crud that it slings up ( Known issue on the GS) So I thought I'd whip up a quick one. I would/will post the pics here, but as I have so many photo's @ photobucket, I have reached my monthly bandwith, and thus will not be able to post again, until the 22'nd. I did not want to let you hang, so I will enclose a link to my FB page, where they are also hosted, and upload them here on the 22, as the account resets.

The 8GS does not have "traditional front fender" but a hugger front fender, like a road bike. They have been known to splinter while riding, with brake lines crisscrossing it, they lock up the front wheel, and you ....ehhhhh... wipe out. It also tends to clog with mud, and block the tire from spinning. By removing that low hugger fender, and route the dual brake lines like a mx bike you solved one problem, but created another. The front wheel ( now slinging up everything) will seize the rad. fan over time, thus need for some protecting is still there. The "half fender swinging aft of the tripple will remedy this.

I know a few people have posted regarding the front fender breaking. There is a good video floating around from a helmet cam where the fender breaks and sends the rider flying.... I think the other big complaint about the F800's designs is that the fender will get gunked up with mud, the front wheel will seize, and you are screwed

I did not know you had done the mod. Sorry, I did not mean to come across as schooling you on the 8GS, I simply guessed you did not have one, and guessed wrong..... Yeppers.... a few thousand miles in the dirt with no fender......

storage

so there is room under the airbox cover right, i was thinkin what if you made an airbox cover that has a little door on it that you could press to open and keys and maybe some folded up gloves or a cell phone could go in there? kind of like where the ktm adv's fuses are. just thinking out loud..

Yeppers.
That is an option, that I have toy'ed with. I do believe I mentioned that in the build thread. I just have not prioritized digging yet. But that was the final idea. A quite nice on, so as to have access to fuses, as you mentioned, as it is a pain to have to remove the cover, because your trail compressor busted the 3 amp fuse, and you had to install a 5 amp unit...... Dont ask how I know this, and I wasn't even airing up my own bike....LOL.

Just got back home.

I am sorry for the reverse order here, but I just got back from 8 days of riding in Silverton,CO. As promished, here is how to build it, now when the Photobucket has been reset.

First, as you make anything, it helps out making a proof of concept. It is the first step, where you sort of get your thoughts materialized, and seeing if the idea will work. That is what I did, and in a matter of two hrs work this one was created. There are several ways to do this, but I chose an 8x18 aluminum plate from Home Depot, as a blank. I bend it into shape, with whatever tools I could find, including a ball point hammer. each about 10 minutes, held it up where I wanted to mount it. Here it is with release agent , and ready for CF application.



I used the 1618 epoxy, as it does not require any post heat cure, and stays very flexible, as I knew that "stuff" was going to beat the snot out of it. Last thing I want is a stiff non pliable shield. 3 layers of 6oz 2x2 twill.....



Then next day broke it of the blank.....



Trimmed it.....



Had to trim the plastic just a little to simplify the mount......



Check the alignment.....




Then as this was a proof on concept, just a little sanding, as I never put too much time into those, in case they don't work....



Then I rubbed a few drops of 1618 epoxy on the sanded out side, and cured it in the sun, and mounted it up.....





It worked fantastically. I rode through rain.....hail.....several about 13000 feet dirt mountain passes, and fan never seized, and interestingly one ride in the rain was on hwy 550 at 50 mph in a deluge, and there were no spray out front with out the hugger, thus no need for a longer beak. Perhaps this is not the case at 80 mph, but at 50-60 mph, there were none.
At Engineer pass......



This was the first step. I have now proofed that it will work. I was mostly curious about the mounting, but light weight as it is it held up fine, and after several hundred miles in some very rough terrain, it is still there.

Next is a bit snazzier looking unit as this one does look a little bland...... Stay tuned.
