Here are some finished pics. The small bits came from Yoyodyne, the brake and clutch lines from Spiegler. New clutch slave from Oberon. Weather here isn't so good, but I'll report on the new controls when I get it all seated and sorted.

Hey Everyone! May's Bike of the Month challenge is now open for entries!
Hidden Reservoirs + 999 Controls
I got the idea for hidden reservoirs from this: http://www.ducati.ms/forums/77-sport-classic/66813-new-bling-2.html#post636896
But I wanted to go further. So my "winter project" this year was to go back to dual discs in front, but upgrade to full-on 999 brakes including matching master cylinders. Here's the single-disc setup from last year:http://www.ducati.ms/forums/77-sport-classic/88147-less-more-part-2-a.html
So I found a set of matching calipers, another narrow band rotor, and some used 999 radial pumps. I wanted the look as clean as possible, so decided to put the reservoirs UNDER the top triple. Careful measuring showed room for the small ones (like your rear brakes). Attempting to make an appropriate mounting bracket was a challenge for someone with no real fabrication skills. I am reminded of the mad abilities of our forum members (hello GTRossi, 848, Muzzman) and am humbled.
Consider my project more of a "Proof of Concept", but it's all together and works! To properly bleed the system, a "filler" reservoir was needed, then switched to the small res for installation. See pics. the little bracket fits behind the headlight & instrument support bracket and uses the same 2 bolts.

Jeff : OK this looks super clean !! Good thinking ...very inovative ... couple of questions...I assume you are relying on a 'siphon effect' once you have the system extremely well bled to draw fluid as need from the reservoirs below ? Also have you thought of tipping the bike over on an extreme angle with the help of a friend or two to see if the system maintains after an event ?
Let me know at the end of the season if you have any problems ....if not I am stealing your idea !
P.S. - Be sure your rear brake is working real good ....

Hey Lee. The brake system is sealed, so the reservoir only needs to be at the top for bleeding. The reservoir exit port must be below the surface of the fluid, but there's no danger of air entering the system unless I'm upside down
. For it to collect any air in the lines or pump, there would need to be a leak.FWIW, many auto cooling systems now work the same way. If air WAS introduced, say, I unhooked the connection between brake line & MC, then I'd have to remove my reservoir and put it back onto the little "bleed" bracket and re-bleed it like I did when putting it all together. I made sure there's room above the fluid in my reservoirs to allow for heat expansion. The only real downside to this arrangement is that adding fluid is a lot more effort than having the res. on the bar. Remember though, the fluid in the line from the MC to the res. acts as part of the fluid in the reservoir: it still feeds the MC.
Thanks. The original concept was done on clip-ons: Sport Classic - Ducati.ms - The Ultimate Ducati Forum
I just moved the location of the reservoirs. The turn indicators are Watsen Design, they're available from JC Pakbikes (and they're NICE and BRIGHT
).Dharma: 1974 GT 550, aka Pandora... Still running, blowing the blue smoke..
LD- Originally, I'd designed an inverted "L" bracket with 2 "wings" to be drilled for mounting holes. I made one, but working with sheet .080 aluminum, a hacksaw, and an anvil didn't give me what I wanted.
So, I hacked off the wings and adapted one of the small original mounting brackets that came with the used reservoir and fabbed a mirror image on the other side. They're attached with a version of 3M VHB adhesive that's good for metal-on-metal. The wings need to angle downward a little to give better clearance above the reservoirs. Ideally, this would be single bracket, but I just wanted to get it done.
The mounting grommets & fasteners are all stock and came with the used reservoirs.And if someone wants to make a kit, I'd probably buy one! It's bound to be a little cleaner that my garage-fab unit...
theoretically, it should be fine, but I'm still worried about it... on a related note, that looks REALLY clean, and I'm probably going to do it
way cool - love the home-brew innovation
it always amazes me that you can do just about anything with a vice, a hammer, a drill and some pliers if ya put your mind to it!
i've heard brake fluid absorbs moisture over time and in hard braking this little bit of water boils causing tiny air bubbles to form which travel up with vibration and eventually collect at the high point in the system. it all happens on a microscopic level, so it's a cumulative effect over time. if you keep an eye on things and bleed every year or so you should be ok.
