1000ds FCR Build

[TAftonomos]

Ah, well, we found this setup works on newer generation engines with the original manifolds. Since they're not exactly easy to find, I didn't think to make it more difficult.

koko: one fellow reported 96 hp on all stock engine. Without any tuning to dial it in. A racer who "did everything" to his engine and made this his last mod got over 115 "real" hp, which equates to about 130 dynojet!

Chris...what runs the ignition?

[krista]

One guy used the Nemesis another Ignitech. Still others have used the OEM efi to run the ignition with a resistor in the TPS. (or I guess we could order one FCR with TPS).

[TAftonomos]

Hmmm...

I ask as I'm at this step with the ds1100/749R I'm building.  Plan was to get it running on the FI as I have all the bits.  But those FCR's (like I have on my 900) are tits...

A resistor for the TPS?  There isn't a MAP sensor, so is the timing curve a fixed one at that point (with the resistor?).  A FCR with a TPS would be pretty cool, and with the freeware duc mapping program out there you could map your ignition via the ECU/OEM setup.

Would be a whole lot easier if Ducati just became a bit more modern and used a speed density setup instead of this Alpha-N based one (or maybe that is a result of a big twin and streetability/pulses....I'm not an engineer)

Larger threaded couplers on the exit side of the carbs were used since the manifold have a larger diameter than 900 manifolds. Also keihin or Sudco kinda doesn't make an off the shelf kit for a 1000 motor but the kit was pieced together without a problem.

Can you take a look at the spigot (what you call the coupler) to see what code is stamped on it?

Pretty Please?

It will look like this (part # is 21D)

There isn't a part number, but I'm sure Chris could answer that Q.

unless those are custom made, there has to be.  the spigot is a catalog part.. 

What say you, Chris??

In order how Sudco measures

A 40.75mm
B 47.00mm
C 26.00mm

ZX11C, ZX9R '94-'97, KTM      32A    47mm   40.8mm     26mm    N195-32A

which is really interesting because i measure the manifold mouth (on the stock ducati manifold) to be about 49.5mm  I assumed it would be one of the bigger-mouthed models.  The spigot for the K100 has a 52mm "B" and a 29mm "C"

thanks for the help!!

So today I swapped out to the correct needles on the carbs and loosely bolted the frame to the motor. Shortly afterwards Ive ran into some clearance issues.



And



I'm not one to be afraid to chop the 2 braces out but will need to reincorporated the braces maybe in a slightly different location, and maybe a couple extra gussets.

Its the crossmember?

Wow.

What year is your bike again?

Yeah its 2 separate cross members. The one under where the battery/airbox mounts to and the othe runs diagonal to near the headtube area.

It's a 03 monster 1000ds frame. Tonight I'll highlight the tubes without the carbs in for a better picture.

[ducatiz]

Humm.. I guess the FI throttle bodies are pretty small compared to the carbs.  I never thought about that.

But those members are necessary.  Not going to be easy to move them.  Maybe cut and sleeve the stub and re angle them but then you change the geometry of the frame..

I'll take those FCRs off your hands.. :-)

[TAftonomos]

Seems like it'd be easier to fab up a pair of intake manifolds to route the carbs around.

It's one of the reasons why I'm considering going with the split singles opposed to the joined up EFI setup...

[ducatiz]

it doesn't look like that would work.  the manifold isn't the problem its the huge Carb body

[Düb Lüv]

Sorry about depriving y'all, but I've been wrenching on a buddys car and holding out on my wife. She's happier at me now, but here's the properly labeled crossmembers that are causing problems.






The "i'm gay" member interferes with the horizontal carb and the "prefers wieners" member interferes with the vertical carb

Now I just need to wack'em off then come up with a different solution.
