Re: Mach1 engine stamp

USA market Mark 3’s had the same frame as ROW Mach 1’s. Bungs attached near the swingarm pivot for the factory rearset controls which required use of the curved kickstarter to clear the rearset footpeg and brake lever. There were also brackets on the left side of the frame for the brake light switch...

Re: Mach1 engine stamp

That's probably correct. But Mick Walker stated that toward the end of production the Mach 1 and Mark 3 were essentially the same specification. Does this mean Mark 3 engines were assembled as Mach 1's? The only distinction would have been a red painted frame (Mach 1) vs. black frame (Mark 3). Early...

Re: Mach1 engine stamp

Being in print does not necessarily make a statement accurate. By 1967 Ducati had discontinued the Mach 1. The Mark 3 and Mach 1 frames were identical other than color. The only difference between the M1 and M3 was the electrical equipment.The M1 had full street electrical equipment and a battery/co...

Re: Location for external oil lines

The only restrictions in the oil delivery is the roll pin in the end of the cam and the roll pin in the end of the crankshaft. I'm considering plugging the end of the cam as there is no reason to have oil exiting there. Not too worried about oil delivery since the oil pump, timing case bushing and c...

Re: Mach1 engine stamp

Re: Location for external oil lines

Since I made this modification to my own 350 Corsa this year, I’ll share what I did and results. I didn’t install the drains since I didn’t want to drill holes in the cases. The cases I’m currently using will eventually be used for a different purpose that won’t employ the drains. I have a couple ot...

Re: small DM stamping 1974 250 SCR/Road

Considering the convoluted story of your Ducati thus far, all this latest development resolves is that someone stamped your engine case with a DM mark. It’s a curiosity. Is the engine case Italian or Spanish origin? This stamp doesn’t emphatically resolve that question. I have limited experience wit...

Re: small DM stamping 1974 250 SCR/Road

DM or DM in a circle is simply an identifier to indicate a Ducati part. The DM stamp was used on lead seals such as the oil pump securing wire or the lead seal on one of the sump screws. Early Ducati replacement parts has a wire retained by a lead seal with the DM impression on it. Some parts had an...
