DS1000SS Nekkid Roadster Build

[Nekkid Tim]

I'm running an M-unit sensor. 

I found them and read up on them a bit and watched a video, but it is not clear to me that I could do anything with *just* the speedo sensor on this bike?

The pick up should work just fine. Shoot motogadget an email to confirm.

 Some progress to report this weekend, although no new pictures. I was able to acquire a Ducati 620 Monster rubber inlet manifold, and using that (and another one that I already had on hand), I was able to mount the velocity stacks.  I also made  screens for the velocity stacks, not enough to keep out sand and dust – but enough to prevent small children and animals from being sucked into the engine!

I  also drilled new holes in the license plate for the bike and mounted it directly to the carbon fiber rear fender, using the stock rubber bumpers to prevent it from rubbing up against the fender – and of course bolted on using two titanium bolts!

Mostly this weekend, though, was fun hosting two grandkids and squeezing yard work in between the massive rainy spells we have been having.

Oh – and the new owner of my S4rs came and trailered it away - one day short of the 10 year anniversary on which I bought the motorcycle.

A little more progress;  hooked up the electrics, installed the battery, and tried turning things on:

"Boot-up":



At rest:




Of course, I still have to figure out where the ignition switch will be mounted, and why the starter button doesn't turn the engine over (maybe because the fuel tank and fuel pump aren't hooked up) and a few other minor items, but progress is being made.

I'll try some more stuff tomorrow evening - maybe install a fuel pump in the gas tank, hook up the tail light, brake light, and headlight....

12,967 miles on the bike; about 300 of them track miles when I used this bike (in a completely different guise) as a track day bike while my other engine was being built (by a builder who shall remain completely anonymous, of course!)

It ran well before I parked it.....

I even bought a Ducati performance enclosed carbon fiber clutch cover because, well..... just because.

Yesterday evening I pulled the fuel pump and filter out of the stock fuel tank, reinstalled it in the ETI FuelCel Sprint tank, and hooked it it up.  It cycled properly when the key was turned on, so that looks good.

Still no action from the starter button, so I swapped the right hand handlebar switch assembly for the stock one from my track bike, just to make sure I hadn't messed anything up when I lengthened the wires on the Euro switch, and got the same results.

So I swapped the switches back.

Not sure what the next debug step is right now, but still trying to slog forward and get this "dry build" completed so I can start riding the bike in "shakedown" mode.

Now that I think about it; I might swap the sidestand switch eliminator from the track bike.  The street bike has the connection "jumpered" [with a "U" of safety wire and a nylon tie holding it in place] and that worked the last time I actually was using this bike, but probably not a bad idea to try tjhe known good solution.

Are you getting voltage to one of the small terminals at the solenoid?  The computer is from a Monster?  What year?  The harness is from what bike?  Immobilizer light flash a code?

Thanks for the reply!

It's a 2003 Ducati DS1000SS with stock harness and stock ECU.  No codes being flashed; everything so far appears nominal except the starter button not triggering the starter motor.  I haven't actually done any analysis, since I just finished hooking things back up the other night.  All I've done is walk back and forth between this project and my DS1000SS track bike (also stock harness, but of course much street equipment missing) and compared connections.

Side stand switch?

From my May 6 post detailing what is left to do:

Install the velocity stacks
Connect the front wiring sub-harness and all connectors and secure them
Install the battery
Install a fuel pump in the  fuel tank
Fill and bleed the front brakes
Temporarily re-install the stock 1000SS instrument gauges (until I can get the Euro GT1000 gauges mapped to the oem SS1000 ECU)
Install the Power Commander III  I'm going to leave this to my race shop - he's done a million of them, including on my track bike.
Oil & filter change  Ordered oil and filters for both it and the track bike today; they'll be here on Saturday.
Gas
Test start
Take it to my local race shop for dyno tuning and Power Commander set up.
Take it to my local Ducati dealer for mapping the Euro GT1000 gauges to the oem SS1000 ECU.  Anyone know what this entails?
Ride it.

Starting to finally get excited about this.   I think I'll WEIGH the bike this weekend!

 Ok, this may not be applicable to your bike, mine is a Bimota with a Pegaso ecu, I have no side stand switch, but if I press the starter button with the bike in gear it does nothing but shut off the headlight. The neutral light must be on for it to start.

Thanks, the bike is in neutral, and the neutral indicator is lit up on the dash.  (see photos above)

Some quality time in the garage today, after church.  My wife is working all day (she's a nurse) and it's raining all weekend; so I can't do the work I need to do in the yard.

Started out checking backwards from the starter motor to the solenoid, main grounds, main power, relay switch power and ground, etc., using my older Radio Shack volt/ohmmeter and the factory shop manual.

Switched the sidestand switch eliminator:

 from the track bike over to the project bike; no change.  Swapped the old sidestand safety wire jumper:

 from the project over to the track bike; track bike still started fine.

Kept reading the shop manual, discovered a pin-out for the handlebar switch assembly, complete with continuity readings.  Checked them all; and the starter button connection stayed open, even when the button was pressed.  Which was weird, because I tried the known good working switch from the track bike a week or two ago, and it didn't start with that switch, either.

So, I checked the pin-out on the track bike, and sure enough, I got continuity when pressing the starter button.   While extracting the switch plug on the track bike, I noticed ANOTHER jumper neatly ny-tied to the front fairing stay underneath the connector:

Checked it; sure enough, it was NOT jumpered on the project bike.   (Of course, the project bike started out with stock brake and clutch master cylinders and now has oem 999 Superbike radial master cylinders) ...  It's the clutch sensor switch connection.  I jumpered that on the project bike as well:

Then connected the switch from the track bike to the project bike:

Siamese Ducatis!!!!!

.... and VOILA!!!   Starter motor works!

So it was back to the bench, to disassemble the malfunctioning switch to see what I did wrong when I lengthened the wires...

Here's the switch when opened and the wire stress relief clamp taken off:

After removing the headlight off/city/on switch's actuating thumb shaft (this is the Euro switch):

After removing the bracket that holds the starter button and other components in place below the headlight switch actuating shaft:

And this is where I immediately saw my error.   The copper contact plate with the two contact buttons should be installed with the contacts on the LEFT; sliding against the contacts that the wires are soldered to, not on TOP, connecting to .... nothing.

Turned the starter button over 90 degrees:

Continuity when pressed:

Reassembled everything and buttoned it back up.   Spliced the Monster headlight wiring pigtail into the SS wiring harness and tested the lights....  I have off/low beam/high beam, but the "city" light is not working.  Didn't test it; that's a task for another day.

Thinking that I'm getting very close now....
