@Buzzer great work as always!
I love your crank trigger, but I am not sure why you need it. Did you completely delete the factory ECU? From your diagram looks like you use an aftermarket ignition module to provide spark and advance curve? Just curious as I had to build my own crank trigger for a 999. But I ended up running it off the alternator end of the crank and used a VR sensor. The standalone ECU could not make sense of the 42tooth timing gear Ducati uses…and from a software point of view running off crank speed was better for the trigger, but I believe your trigger on the layshaft could be used as a cam sensor in addition to my crank sensor. If you did use a standalone ignition would you mind providing some data on it? I imagine it might be useful for some other projects and might be a bit cheaper and less complicated than the full standalone ECU I use.

Happy to help! I use an ignitech TCIP4 ignition unit which is very good... its actually plug and play off the original induction sensor that works off the toothed wheel, but I had problems with that hence moving to a hall setup. The ignitech is easily programable and supports many functions, and comes with its own software so you can make changes (dynamically as well!) have a look at their site https://www.ignitech.cz/en/

happy to take any questions... just send me a message

Thank you for the info sir. I need to do some research, looks like they make plenty of options, but it looks intriguing because being able to purchase the options you need. My PE ECU is loaded with everything weather you use it or not…I do like that it can program nearly any sensors etc, not tied to proprietary hardware.

Fitted the new cambelts today… I like the Gates carbon Drive app to tension the belts. It measures the frequency of them when you give them a twang, like a guitar string, very sensitive and accurate. I set them to 110 HZ which also “feels” right.

I also went to pick up the oil cooler pipes I had dropped off to have the ends crimped on…I just don’t have the tool to do this. The miserable git plonked them on the counter and said £20… I looked and he had fitted different size ferrules on the ends… when I pointed this out he shrugged and told me it didn’t matter… well it does to my OCD… he was not happy when I refused to pay! This is why I hate putting work out.

into the detailed jobs at the moment, in preparation for start up. The oil cooler was pretty tatty so I left it in a container with some thinners in the bottom for a few days, then washed the paint straight off. As its aluminium and I was going to paint it, I grit blasted it before giving a a thin coat of etch primer, followed by a couple of coats of satin black, which I prefer over matt. It came out really well.

Then onto the carb installation. The outer diameter of the carb inlets are different to that of the fuel filter, so I needed a “T” piece with different size ends. I made one out of brass and silver soldered the parts together. Finally I needed some cable adjusters. I popped to the cycle shop where I buy my bowden cable to make the throttle cables but they didn’t have any suitable. Again I ended up making these out of brass and a couple of bolts. The yellow tube is Tygon, made for Ethanol fuel. its very flexible and I like the idea I can see through it! It works best with Mikalor clips which are quite neat.

Finally I fitted the frame number sticker with the VIN number on, just to keep the MOT man happy. one of the problems with blasting and powder coating the frame is it becomes very difficult to see the frame number.

One aspect of a build I like to get right is the throttle action... too quick and action and its jerky to ride and often heavy... too slow an action and it becomes two handfuls to fully open and I hate that...

I popped the cable on with the twin pull throttle of the Multistrada and it was just too quick and heavy... I needed to take 1mm off the diameter where the cables run. Of course you cant just pop it in the lathe as the cable boss prevents that... I looked at doing it in the milling machine and couldn't see any way of doing it... so I came up with this!

DREMEL! Can't beat it! Well done.

I dont know what I would do without it! its not a Dremel though... I broke three before buying a cheap copy off Amazon for a third of the price that has lasted a couple of years now!

Well I would like to say it started first time… but it didn’t… I would like to say I found the problem in 10 mins… but I spent HOURS looking why it didn’t start. In the end I tracked it down to the fact that I had placed the magnets wrong on the ignition trigger wheel! easily sorted soon as I spotted it.

I wasn’t really in the market for another project just yet… but when this came along VERY cheap, I couldn’t resist! Its tatty but is a runner and sounds sweet! I think it will be a good basis for a project… I have done 9 Ducati’s now, need a change!

I am So SO annoyed with myself… the tank has taken days to get to the right shape… I etch primed it… prefect… 2K primer… perfect… just needed flatting before the base coat. Unfortunately I went through to the bare metal on an edge… Not wanting to have to fill the gun with 2K again I used some 1K primer… As the base coat dried… the 1K primer reacted… lesson learned!

Oh man, I did that with a Moto Guzzi tank once. I was so devastated!

@Buzzer I know you have the cases vapor blasted. But I am curious about the finish you achieve on the motors, it’s stunning. It appears you polish the alternator and clutch covers, do you clear these? Do you paint the cases, cylinders and heads, or is that clear after vapor blasting? Thanks for all your tips.

yes, the cases are vapour blasted and the outer cases polished. I never use clear over the polished alloy... in my experience it always flakes, and its easy to keep them looking good with a thin coat of ACF-50 which I also use on the vapour blasted cases.

There are good vapor blasters... and not so good ones. A tip is to pull a microfibre cloth over the surface... if it snags, even slightly the finish is not good! I have painted engines in the past, but prefer not to... however I have seen some amazing results with creakote (UK Cerakote, Colours & Supplies | Cerakote UK) and will concider using this in the future. they do great colours as well!

Well the tank is finally finished, bar for a mop and polish. It took a lot of time to rectify the paint reaction... I had to sand back to bare metal, and re primer the lot... I then put the tank above the radiator in the small bathroom and left the radiator on for 2 days to fully harden ...I had complaints about the smell of paint!!!

This will be my last post for a while... the Ducati build is almost at an end and before I start the next project I have a list of house DIY jobs to do :lol

this has been my 9th Ducati build / restoration so I fancy a change... the next bike will be a Guzzi 1100 :D

For now, here is a short video that tells the story of the last build...

merry Christmas!

Having owned two first gen Multis, I was completely invested in this build. Though hard on my self esteem, being completely talentless, I thoroughly enjoyed the build. Hats off!
