SuperTenSteve, you can easily find prefab material. Just google carbon fiber sheet. Multiple sources will show up. Just cut it to shape and you're good to go.
CF can be dirty and nasty to work with, but I don't find it to be any worse than fiberglass. The key to success is a good quality vacuum to keep the dust under control while cutting and sanding.

Re: Rear wheel splash guard/make some for sale!

Very nice job. Why don't you make a bunch of these. I am sure that they would sell...quickly!

I'm sorry guys, but I don't plan to make any of these for sale. This thing was a time consuming pain in the ass to make. Even if I splashed a mold off of mine, I still don't see how I could do it at a fair price? Materials alone would make it cost prohibitive for resale.
But out of curiosity, would what you guys would consider a fair price to be for a part like this? Either fiberglass or carbon fiber.

No worries.

However, in my opinion, whatever you charged WOULD be fair.

My momma always said, "son, in this life, you can have almost anything you could possibly want, as long as you are willing to pay the price"

She didn't say anything about the price being unfair. :)

Not to side track the thread. I bought a new '13 G650GS here in mainland China Oct '14, in preparation for an overland trip from Ningbo (near Shanghai) China, through Laos, into northern Thailand Jan & Feb this year. Since my plan was to ride and not be put off by any trails and having ridden northern Thailand the previous Jan & Feb '14 on a hired CB500X, knew what I was in for. A big dirt bike was not ideal choice so I wanted a mid displacement DS/ADV. The G650GS I feel is a more tried, tested and reliable platform, and one of the few affordable choices available in mainland China. It doesn't have a computer like the F700GS/F800GS, and cost less to boot. Mind you the wee G still cost $20K which was more than my S10 cost in OZ. But it is what it is.

I completed the trip (departed 2 Jan, arriving in Chiang Rai, Thailand 5 Jan - arriving back to Ningbo, China 5th March). Once again, I luv'd being in Thailand, 1000 times better than China IMO.

In amongst all of the farkling and so on of the wee G in preparation, I was looking at the addition to a rear wheel splash guard too - which are available here. In the end, after seeing how slash guards seem to snap due to vibration over time, I decided to go with the KISS mantra. Instead I fabricated/added a rear mud flap. I simply bought a couple of thin rubber 'flaps' and took a couple of thin alloy flat sections which I bent at a slight angle to 'feather' the mud flaps rearwards slightly. I installed the bars in behind the rubber mud flaps so the flaps are all one sees from the rear. The flaps are effective at minimising the crud, dirt and mud thrown up the rear and covering the rear side of the top box.
Cost $2 plus a little bit of my labour.

No issues and still can easily remove the rear wheel. Replaced the OEM Metzler Tourance's with Karoo 3's as I did a lot of knarly offroad and single track in northern Thailand, that the XT1200Z would have been too heavy work IMO. Even carried three new Karoo 3's back into China and arranged freighting from Xishuangbana.

All in all, very happy with my KISS mud flap, and still works after completing 22K km in two months. While in Thailand, I met some guys riding S10's doing trips round-and-abouts. Some were from Malaysia, Singapore or other parts of Thailand, and it was at those moments, I wished I was on my S10. But realistically some of the tight technical dirt we rode, even the wee G650GS was a handful, meanwhile the CRF250's lapped it up.

Right back to regular programming...

Bikerdoc, your suggestion seems smart for someone who does a lot of offroad riding.
For me, making this mudguard was just a motorcycle related winter project that I took on to keep busy during our snowy winter. I like the way it looks on the bike, and if it breaks, it breaks. I'll either repair it, or make a new one. Who knows, I might need another project next winter.
It is funny to me how polarizing some folks outlook is on this homemade accessory. I posted a photo of it on a S10 facebook page and many were critical because it looks to "BMW". Personally I find that hilarious, but surprising. I guess there are some very loyal Yamaha owners out there?

Nah! Looks too Ducati Diavel, or any of the newer ones! Who cares! Most of us like it, more importantly YOU made it from scratch ::008::

Well, it only took one ride and one very bumpy dirt road to total the new mudguard. I guess it's back to the drawing board for me.
I stopped and checked it 2 or 3 times over the first 50-60 miles, it looked fine so I thought I was good to go. I went down the bumpy road without giving it a second thought. When I stopped for lunch, this is what I found. Although I think I know the approximate area where it most likely failed, I didn't go back to try and find the rest. Time to start over from scratch with a better design I think.

Sorry to see, as it looked like a promising idea.


Better luck with your V.2

Could it have failed because CF is too brittle? Although strong, perhaps something with more 'flex' is required, ABS plastic is he norm for this sort of application, but I, like many await your 2nd Gen version..... ::008::
Perhaps run it by RCinNC, as he makes a ton of good stuff with aluminium, maybe a collaboration?

The bracket on the swing arm fit well but it wasn't perfect. It needed to be made a little more secure to prevent the arm from moving in a vertical plane. I had an idea how I was going to do it, but hadn't gotten around to it yet. Yesterday I was anxious to get out for my first ride of the season, so I didn't take the time to remove it from the bike before I left. I thought it would be ok for one ride. I didn't give the slightly loose mudguard a second thought when I decided to hit the bumpy dirt road.
What I think happened is that the arm started bouncing when I hit the big bumps. It must have moved enough to touch the tire which just grabbed it and snapped the thing into pieces. The amount of material I used was more than adequate for the application. If anything it was probably overbuilt. It just wasn't secure enough on the swing arm.
I'm really not too broken up about it, live and learn. I'll just try and learn from my mistake and do a better job next time. Just another excuse to get back into the shop to make something. It's certainly not the first time one of my ideas didn't work perfectly on the first try. Haha.
