Got the Ducati staring, running, idling and restarting reliably over the weekend
The carb rebuild has definately helped sort the starting and plug fouling.
But it is still just a little rough and stumbles slightly off-idle.
Its not fueling quite evenly
Does anyone have any experience with carb sync, guages, etc they would care to share?

Did you ever see the long thread that OddDuck posted about his efforts with a Ducati? I dont know if he was ever successful in getting it to where he wanted it. Was a while ago

Its an MHR with Dellortos.
I'm nowhere near the engineer that Old Duck is.
But I think I can improve the running further and was wondering if syncing the carbs would help.

From my own experience with both a Darmah and MHR with Dellortos yes it will, I had the same off idle stumble

So how did you do it? - someone good around town? bought guages? - if so what sort? or?

some people have the ear for it with for v twins, find someone who knows the generation of bike is a start
also actually think what the person needs to know, ie a ducati is not enough, it could be anything from single to four, injected etc, give them the info, mileage helps so they know if they are looking at worn parts too.

Where are you for a start. I've still got the gear and have been doing it for lierally decades in ChCh.
Bevelhead Dinosaur
I'm in Chch.
Would you be prepared to give lessons?
Happy to make it worth your while.

Phil Sutton did both of mine, he's worked on Bevel twins for decades, made a very noticeable difference, dunno if he's still working on them

You also willingly put dellorto carbs onto bikes
If mike was alive he would want me to recommend these.....not that he likely cared about the off idle cough.

Not satisfied with some rough running, I've been wanting to give the MHR's carbs a wee tune-up.
Thought if anyone was going to look at them, it better be me.
So I finally get back to the back of the garage this weekend and drag the bike out.
The plan was to change the fuel, give the carbs a tickle and go for a ride.
Even with fresh fuel she did not start too easily, idled ok, but the acceleration just was not quite right.
Think I might have fond the source of the problem....
To loose one adjustment screw is a misfortune, but two is just plain careless
Had to take the Suzuki for a squirt to stop the screaming inside my head

I-I love the colorful clothes she wears
And the way the sunlight plays upon her hair
I hear the sound of a gentle word
On the wind that lifts her perfume through the air
I'm pickin' up . . . .
She's giving me. . .
Good, good, good,. .
Don't you look at my accountant.
He's the only one I've got.

I wlll generally bench-set the butterflies on carbs, Just a visual to see the plates are ~1/3 over the pilot holes.
Air pilot screws get set 2.5 turns backed off "nipped up"
On a 4 cyl you balance two pairs, then bring the two pairs together with the middle adjust.
Once she runs, and is warm, then you really need a manometer. Drill and tap somewhere upstream from the carbs for a nipple.
A couple of yards of brewery hose (8mm clear plastic) is good. 1/2 fill with 2 toke oil; connect each end to a cylinder, keep the tube upright and lower than the carbs; the different vacuums will show up pulling the oil up one side or the other. Tweak carb screws to balance.
Even numbers of cylinders help, not sure how you'd balance 3.
There's also a method of "reading" spark plugs by cutting out the ignition while riding. I've never had to do that so not sure how correct it is but could be worth searching up.
TLR? Slap a turbo on it.
