Started dry assembling the various body panels that mate up with the tank.

The left hand side panel fits nicely with the tank...

Image

But the left hand top side panel doesn't have an even panel gap with the tank...

Image

It looks like it needs trimming, but I'm going to take it all to bits and put it back together several times and make sure it goes back together in the same place each time before I cut anything.

Fit round the back is great...

Image

Image

Also test fitted the sprauncy new carbon fibre binnacle surround...

Image

The rider's seat is back from the upholsterer and he's done a top job, getting the original saggy vinyl drum tight and nice and neat underneath. The seat base needs some flap wheel work to remove some plastic to make it a good fit on top of the tank...

Image

Throttle cables on the way back from Venhill, should be landing tomorrow

Epic. It's shaping up beautifully.

Percussive maintenance,I like it. Sounds similar to my skill set. :lol:

Brutal...

...but effective.

Clearance is now equal both sides. Looks like I'll have to fabricate one custom front tank mount but that's not the end of the world.

Onwards and upwards...

Will you need to heat shield the tank or wrap the exhaust where the exhaust runs close to it?

No, there's a good 20mm air gap between the exhaust and the tank and the tank is a very good conductor of heat away from a local source plus the mass of the fuel will act as massive heat sink.

Been a couple of weeks since the last update.

In no particular order....

Healtech quick shifter fitted.

Image

It's a nifty looking little piece of kit, here's hoping it works as well it looks.

Connectors for the Panigale injectors identified, ordered and delivered. A mil-spec connector liberated from the stores at work and the injectors are now wired and plumbed in...

Image

Image

Fuel lines are all done, with a proper Parker brass high pressure Q/R fitting used rather then the dubious plastic ones so beloved of Ducati and ebay...

Image

Wiring harness for the whole bike is taking a LOT longer than expected; every single wire is the wrong length and either requires shortening or lengthening. I'm about a third of the way through at the moment, but had to leave it to get the bodywork sorted and ready for paint.

As previously reported, the panel gaps between the fairing side panels and the tank were terrible.

Initially I trimmed the side panels back to at least make the gap even...

Image

...but that looked terrible. However, I had an idea on how to fix it so thanks to ebay I managed to buy a set of tatty side panels and these were sacrificed so that a strip could be cut from them....

Image

The strip was then, with the aid of the soldering iron, tacked in place on the original side panel....

Image

...and fitted to the bike...

Image

That's better!

Fully plastic welded in place, using offcuts of the scrap panels, and sanded back..

Image

...and the same done on the other side...

Image

Job's a good 'un!

Off to paint on Monday and I'll get stuck into the harness over the weekend.

The devil's in the detail for sure.

The tank front mount that was stuck at the plating company in Sheffield, due to them shutting as a result of a covid outbreak, is now back in my possession replete with a shiny YZP finish.

Wiring loom is finished....

Image

Image

Image

It took two 1098 looms, one original multistrada loom, loads of different coloured wire and about fifty cut and splice joins.

Drop it back into the bike, connect it all up and turn the ignition and hope it doesn't burst into flames. I need to nip over to see @Couchy and make use of his crimping tools to shorten the main power supply lead to the solenoid and then in, theory, it's ready to start.

Got a coolant leak - weeping from the water pump cover - to sort and then it's over to Cornerspeed for a cold diagnostics check and then some fuel in the tank and maybe it starting. Next week hopefully....

Nah, been super busy at work and I had to self isolate for a couple of days while waiting for a COVID test result. Negative thankfully. And with the bike being in the garage at home and the garage being unheated and it being fucking cold at the moment I've not been doing that much on it, managing an hour here and an hour there before having to come in to the warm...

Things I have learnt today.

The single black wire with a ring terminal on the end that I could not find on the 1098 wiring diagram and, as a result, I dismissed as unimportant and summarily chopped off and threw away is not as unimportant as I had thought...

Got the loom connected up to everything except the ECU and turned the ignition on and started testing all the lights, horn, dash etc. A minor snafu with the tail light connector, translating the 1098 harness to the Multi tail light assembly required the connector to be de-pinned and remade. But other than that all the smoke stayed in the wires and nothing went "ppffffzzzzzzzt".

Connected up the ECU and turned it on but the dash didn't go through the expected welcome message and the neutral light and oil pressure light didn't come on. Scrolling through the dash brought up "CANBUS 38.0" as an error message.

Quick bit of googling and it turns out a common cause of this message is the ECU 0V lead coming adrift. "What ECU 0V lead?" thinks I. "Aaaaaaaaah, that'll be the single black wire with the ring terminal....".

Good news is, with a jumper wire from the battery -ve terminal to the ECU body, the dash powers up with the correct welcome message and the oil pressure and neutral lights work and the throttle body stepper motor cycles. The even better news is there are no faults of any description on the dash so, fingers crossed, there's no other issues with the loom I've made.

Bad news is I've got to disconnect everything and take the loom off the bike and strip a chunk of it back so I can splice in the ECU 0V lead.

Bike is booked in with Cornerspeed for a week tomorrow for a final check and then, all being well, starting it for the first time.

It's safe to say the f**king thing is fighting me every inch of the last few yards....

Went to fit the custom throttle cables Venhill made, to my specification a few months ago, to the bike last weekend. The closing cable was spot on but the opening cable's inner was coming up too short. Don't know whether it was my specification or Venhill's manufacturing. Irrelevant now, so posted them back and luckily I was down near Venhill yesterday for work so was able to persuade them to do a rush job and let me pick them up.

Fitted them this afternoon and now the opening cable is, really, too long. With the adjuster wound all the way out it's just got the right amount of play at the throttle but whether I'll be able to take any slack out when the cable beds in is a worry. Anywho, I'll cross that bridge when I come to it.

With the air box in place and the ECU and injectors all connected up there were no faults logged on the dash so I thought I'd chance my arm and at least see if the engine would turn over. No fuel tank fitted and the coils disconnected and a press of the starter button...

Bugger!

Starter motor spins away but no engine roundy-round sounds and no "duff duff" from the exhaust.

Looks like the starter sprag is u/s.

With something as bespoke as your bike,there's always going to be details trying the patience.

Take comfort in providing a great and continuing read over lockdown. :thumbup:
