Nice job! Congratulations to you and Zeke - oh, and welcome to the Forum 8-) . Yup, Bob is missed. Even if some of his posts occasionally took some de-ciphering :? , he sure knew his stuff :ugeek: , and was very generous with his time in explaining it to all us numb-skulls ... Please do keep on enco...

Re: direct replacement 6 Volt rectifier for Monza

..as its extremely simple and basic system it doesn't even regulate the voltage...!!! You SURE about that? Not so, according to the article that Hans linked to. Just to get back to this, and hopefully forestall any repetition of any misunderstanding. This device is indeed both a rectifier AND a reg...

Re: Carb novice requests help

Above idle, the system that comes into affect next is the the slide cutaway. The smaller it is, the richer. Yours is #40. <snip> Good point, Jordan - thanks. Forgot/overlooked that :? ... FWIW, here's the Dell'Orto explanation, in pictures and words: http://imghst.co/81/bSfXcPyeCe.jpg

Re: direct replacement 6 Volt rectifier for Monza

At one time long ago I recall coming to the conclusion after some circuit analysis that the chokes served as a crude but effective voltage regulator as it was created from an era likely before the advent of semiconductor voltage regulators. Check, Jim. That's what I thought, too (see my earlier pos...

Re: direct replacement 6 Volt rectifier for Monza

Over the years people have made up rectifiers I was hoping to find one that would do the job <snip> Jim will tell me if I'm wrong; but I'm pretty sure that pretty much any full wave bridge rectifier will do the job. I fairly confident this is what Phil Hitchcock advises. And also have a look at thi...

Re: Carb novice requests help

(Apart from the very first models), The standard Dell'Orto carb for the 350 SCR was a VHB29. So yours is neither the 'right' size nor the 'right' type ;). Which risks making things a little more complicated ... :? FWIW, the spec for the VHB carb was: Atomizer: 265M Mains: 110 Idle: 45 Needle: V13 Sl...

Re: UK Ducati 250 mk3 1973

Thanks all for the advice. I bought the bike today, it is a project, complete but needs restoration. The bike is a non runner, has been laid up for 5 years and exposed to the elements <snip> Hi Alex, Congrats on the purchase! Given the bike's history, I suggest you should assume an engine re-build....

Re: 350 valve adjustment

1969 is right for your engine number.

According to the owner's handbook from May 1968, valve clearances are 0.10mm (0.004" if you insist ;).
