Re: checking engine oil pressure

Typically, the cam has a roll pin inserted in the threaded end of the cam to restrict oil. Your local hardware store hopefully has appropriate sized pins that work. If you want to completely block the oil passage to the threaded end of the cam (so all the oil is directed to the rocker arms), press a...

Re: Arias piston clearances

If the alloy of the aluminum is high silicone content (i.e. low coefficient of expansion) then .002" will work fine. Could probably be tighter. Honda has been running pistons at this clearance for many years. I have an XR628 with a bore size close to 100mm and the piston clearance is .0018"...

Re: Titanium rod kit

Carlo Leoncini is active on the Ducati TT and F1 site (http://ducatittandf1.com/). You'll see many postings from him there. His work is very highly regarded by the group. Haven't seen any references specific to the bevel singles parts that Carlo makes but he has provided many Pantah parts to happy c...

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...
