Very nice sir!

On my ST2 Project I reused the front cover, but only the forward facing section for the same reasons you have here. I cut out the side portion.

here is a short video of how it sounds.... I did take it up the street and the throttle response is fantastic!

Great job as always, I look forward to your next carby conversion.

I did have to laugh though
a bit of googling suggests that chain breakages, and subsequent case damage is all too common on some Ducati bikes! Plenty of case savers on the market and quite cheap, and a dam site cheaper than new cases!
Case saver = condom
open belt covers = no condom.... while picking up a date from a HIV support group.

I see as many open belt engine failures as I ever have broken chains. best thing with the chain is to use a good quality chain with a rivit link and you will unlikely ever need a case saver.

Made a stand today to keep it upright and safe in the garage… The wheels are idler bearing i changed on a car recently when I did a can belt... makes it roll nicely. Also fitted the seat badge and tank protector.... with all the Corvid 19 issues its looking like I won’t be riding it for a while…

My ST4s seemed to run cooler with the fairing off, but I never thought of getting data, since I planned to keep it for touring. This is exciting, keep going!

What? Unless the bobbies are out to limit the use, over here (on this side of the pond), I see a lot of bikes out. It's our way to "self isolate", get fresh air, etc.

My main fear is at the petrol pumps. I carry disposable gloves, and am very careful with what I touch while I'm there.

The reason they say not to ride unless essential is if you have an accident with any "risky" pursuit including sports you are putting health workers at risk that could be avoided. That's for us kiwis anyway.

They have eliminated any open fires even backyard enclosed type until after pandemic ... similar line of reasoning .... can’t say I totally agree

Not to mention, you're almost guaranteed to get exposed if you wind up in the hospital. And you likely may not receive priority care. Hospitals right now are a crapshoot.

Here in the UK we are banned from making unnecessary journeys... best not ride I guess

Scratching around for jobs to do now while I cant ride it! made some frame finishers…

well I came to make the last frame finisher that was actually a different size to all the rest... then I noticed that Ducati had cut the frame at an angle! So I had to make an angled finisher... this took some setting up in the lathe to get the angle just right....

Oh man. Two posts on frame plugs. Luckily, this isn't the good old days at duc.ms. Hahaha!

Exceptionally nice work. You created an excellent machine. Enjoy it when you can!

My apologies about the inside joke.

Have a good one.

thanks! i have enjoyed building it!

As an aside from working on the Ducati.... I have been busy doing a job on my Harley V-Rod today...I changed the oil and filter and in doing that took the opportunity to check on the timing bolt in the engine that can come loose on some bikes, which wrecks the engine! nice and easy job, just drain the oil and remove the alternator cover which comes off easily. I checked the torque of the bolt before I removed it and it was tight... However to be on the safe side I removed it and cleaned both the internal thread and the bolt, and used some high strength thread lock on there as advised by the factory...

Nice!!
Are the Allen screws in your plugs just a design feature or do they serve a purpose? I can´t see how they work if they do :)

the screws are just decorative....

None Ducati this time, but with lockdown still in place I helped a mate out who needed some brake calliper pistons for a Norton Commando he is rebuilding...

I made two out of stainless steel for him as the originals were pitted quite badly... took a while to grind a tool to the correct angles and get the speed of the lathe right to get a nice finish, but I got there in the end...

Been a while since I updated....early May, lockdown continues, still can’t ride, it’s very frustrating to have bikes on the drive and not ride them!!

done a few more jobs like programme the ignition advance to get a steady tick over, and importantly retard the ignition at cranking speed to give the starter motor an easier time.

Also balanced the carbs. for years I used a mercury gauge for this but a mate borrowed them and broke it! so I bought a set of gauges, but noticed I could get it closer by ear! so I checked the gauges by connecting them to a single vacuum source and found they were all reading differently! hence the single gauge with 5 valves. the 5th valve provides damping to the gauge. I have found you can get a perfect tick over with this method.

lets hope we can ride soon!

Middle of may and lockdown has eased a little and I have been out doing a few miles... It runs REALLY well on the carbs! the throttle response is amazing and it feels very crisp and lively! made a few adjustments to the timing at low RPM, but the jetting feels OK, and a plug chop confirmed its not far out... just need to put a few miles on it now... its VERY loud though!

will post a video soon as I can get someone to take it!

Been out and about the last few days bedding things in after the rebuild... one thing I noticed was its slow to turn over when you start it. I had upgraded the cables, and the starter itself was good, so I had another look at the timing. When I did the map, I had the first RPM point at 400 with 10 degrees BTDC and the second at 1000 again with 10 degrees... so i changed this to 5 degrees from 400 to 1000, so there is not so much advance at cranking speed.
I also configured the software so it did two full dead revolutions before it sparks... this means the engine is properly spinning before it fires... It really spins over now and starts MUCH better
