|SDS||You did a fine job, sir. Thanks for documenting the build, and thanks for sharing.|

Just to finish this off, and potentially help anyone else who decides to use a 1000 DS engine on carbs.... here is the final settings. with this it runs an absolute treat! Liam Venter pointed me in the right direction, it was the tooth count on the cam wheel that was the issue. I now have rock steady tickover, and steady advance that matches what is actually happening and what the software says!

Thought I would update as although the bike went well enough, it missed that sharpness of the original bike… I thought it may have been the carb conversion, but it didn't feel like it...
so I checked the timing with a timing disk and a strobe, and guess what, the values in the matrix in the software didn’t correspond with what was actually happening on the engine! the bike was actually retarded throughout the rev range. I think this has something to do with the way the software is configured, I have emailed the manufacturer to see what they say. As a work around I set about changing the values so I had correct advance using a timing disc and a strobe. its now running MUCH MUCH better, and feels far more crisp! here are the before and after maps. although the second map says its getting 42 degrees advance, in reality its 34. It also ticks over much better... at the moment the TPS option is off... I will wait to see what Ignitech say before I do much more
below is a link to a 1 min video...

Well the miles are increasing! Its running really well and I have done quite a few trips out with it, and I am enjoying the ride. Slight mishap... forgot I had left the tap on reserve and ran out of fuel!

|fulton246||What an amazing build. It has a nice cafe style to it. I bet it looks even better in person.|

Been out and had a good run of around 50 miles today, took a few pictures... The bike runs REALLY well, nice and smooth pick up, and revs to the red line cleanly, I am pleased with the result. I would say its down on power over the injected bike, but not much, and its enough for me!
A couple of things I need to change... the mirrors are crap in that position, and also the throttle is too slow, I need a faster action, and will be on the lookout for one next week.

new thread on the ST4 build started here...

I normally start the hunt for a new project in the summer, ready for the following winter to be sure I have something to work on... this year its all been a bit quick! I have not quite finished the Multistrada when along came another Duke... an ST4s this time. it runs well, bit is a little tatty ( the pictures make it look better than it is...) It was a bargain price, so I could not resist it!
For the moment I am going to sell off some of the bits I definitely know I wont use, and then put it to the back of the garage until the winter, when I will start the build in earnest... thats not to say I cant do little jobs :-)
not sure what this will be just yet... time to think about it!
I may start another build thread?

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!
