Re: SSi remote float.

Solder on the slide to adjust idle? There should be an idle adjustment rod installed in the cap of your carb that engages a slot in the slide to set slide position. In the "Tech" section of this site there is an SSI tuning manual. This manual describes the procedure for setting float level...

Re: Dellorto PHBL 22 AS Jetting?

The starting (enrichening) circuit that is deployed with the “choke” lever is completely independent of the main fuel metering circuit. So installing a leaner needle jet will not lean out the starting circuit. But it sounds like a leaner needle jet and a leaner starting jet are going in the right di...

Re: Conrod kits ?

Re: Mazzuccelli rod set. I have a few factory Ducati big end pins for NC 250 that measure ~27.3mm. Also have a set of flywheels with big end bore ~27.3mm. The flywheel big end bore was obviously rough cut too big for 27mm (a small portion of the rough cut is still left) so the flywheels were finish ...

Re: Conrod kits ?

Curiously,Samarin lists a rod set for "DUCATI 200-250-ROAD-24H 4T" but appears to use a 27mm straight big end pin with a 35mm O.D. big end bearing. This is a bit smaller than the standard Italian Ducati rod (27/32 stepped pin with a 39mm O.D. big end bearing). Samarin, being a Spanish comp...

Re: Dellorto PHBL 22 AS Jetting?

Another thing to consider is the heat range of the spark plug you're running. NGK is the manufacturer I'm most familiar with. The heat range recommended by NGK is a B6HS, which is a pretty hot heat range. If you're running a colder heat range, this will exacerbate your starting/jetting problems.

Re: Dellorto PHBL 22 AS Jetting?

I’ll share a few guidelinesthat were recently reinforced as I addressed jetting issues on two of my own motorcycles. Assuming your cam timing is correct and you have an appropriate exhaust system installed, it is imperative that you have no air leaks in the intake system. This includes the mating su...

Re: Conrod kits ?

The Mazzucchelli rod kits are probably adequate for your purpose. They offer the correct length 135mm rod with two options for crank pins: 27mm & 30mm. You need to verify the diameter of the big end pin bore in your flywheels. You probably have a 27mm pin but verify to be sure. https://www.nuova...

Re: 4 speed shift pattern?

So if the transmission is in neutral or in between gears (i.e. false neutral) the shafts rotate freely? But when a gear is engaged the shafts become difficult to turn? It appears that the shaft shimming is ok. There should be no drag on the shafts when a gear is engaged.

Re: 4 speed shift pattern?

At what stage of assembly are you? Cases assembled or apart? Clutch assembled? Is the selector box installed or are you selecting gears by turning the shift drum shaft? Ideally for testing, you would be turning the input shaft by hand while effecting some drag on the output shaft. As you turn the sh...
