The bike is now running, it sounds fantastic!  I balanced the carbs with the vacuum gauge.  I prefer to use a single gauge as its far more accurate…  if ever you have a bank of gauges connect them up to a single vacuum source and check they are calibrated.  most are WAY off!  with a twin I simply use a “T” piece and clamp the pipes individually with a pair of  pliers, alternating from one cylinder to the other…   the clamp in the picture is to damp the needle on the gauge.  Its a VERY accurate way of doing it…  makes a huge difference to the tick over.

Below is the initial configuration of the Ignitech ignition.

Well here you go, just a short clip...  I did take it up a very short private road and it pulls well and sounds...  LOUD, but awesome!

As always there are snags on a build like this…  I have always been worried about the head of fuel the carbs will get…  it was OK with a full tank, but not enough to give me a reserve position on the tap.  This was overcome by fitting a small electric pump, but this showed a weakness in the float needles in the carbs,  Any leaks here is above the engine so I bought some new and genuine float needle valve assemblies and set the float heights to 14mm with a gauge I quickly made up.  Easier to do if you clamp the float into position with a washer… no leaks after they were fitted…

What ignition are you running?   My experience with a car running 2d and then converting to 3d was chalk and cheese...  the difference was amazing.   Hence no hesitation going 3d with this conversion.

Im running an Ignitech V88. I have tuned it and the carbs to a level that is quite good, but of course there are some ways in which Im not getting the most out of the motor.

I would say try a TPS...  I have used the one off the Multistrada...  I thinks I have seen that someone makes a kit to fit your carbs, but I cant remember where... it would not be too difficult to make something i guess...

I had a 150 BHP crossflow in a Westfied years ago...  it was a manic car to drive...  it had a 2D distributor on it, and did 20MPG...  difficult to drive normally day to day, so much so my wife refused to drive it.  I then fitted a 3D ignition, and it transformed the car!  and the MPG went up to over 30 MPG!  have a look here...

 FCR kits for some makes came with a TPS so getting those kit parts from the importer shouldn't be too hard.

A couple of pictures under the seat….  the alloy rod is the tank stay velcro holding it in place! 

wiring is nice and simple on this one! I mounted the ignition module on stilts with small rubber feet ( i used the original ones from the multistrada clocks) to insulate it from vibration.

This is probably the last post for a while...  I will update again once its been road tested...

anyone interested, this is the link to my blog, where I have my other projects...

But for now, the hunt is on for another project...  I would like it to be another Ducati, but I am not ruling anything out!  so if anyone has anything at the back of their garage gathering dust that they might sell... get in touch!

You have some serious build skills.

Beautiful job!  [thumbsup]

That under seat arrangement alone is worth a ten [drool]

I'd like to see the rear light strip (?) moved to the seat cowl. Or under the frame. Let us see the frame!

I managed to get the raw data from some Ducati ECU files.  I have colour coded it to see the pattern of the values in a visual format (isn't Excel brilliant!)  Across the top is the RPM, and down the left is the TPS values,  The lower values are throttle closed.  these follow what I would expect to see on a 3D advance map.  I hope to replicate these in the ignitech map on the bike.  Just need some decent weather to ride it!
